Mount Ibuki (伊吹山, Ibuki-yama) is a prominent mountain in central Japan, rising to an elevation of 1,377 meters on the border between Maibara in Shiga Prefecture and Ibigawa in Gifu Prefecture, marking it as the highest peak in Shiga Prefecture and the namesake of the Ibuki Mountains range.[1][2][3]Renowned as one of Japan's 100 Famous Mountains (Hyakumeizan), Mount Ibuki is celebrated for its striking pyramidal shape, diverse alpine flora, and heavy winter snow accumulation, with a world-record snow depth of 11.82 meters recorded on February 14, 1927, making it a key site for meteorological and ecological studies in the region.[1][2][4] The mountain's summit features expansive flat grasslands that bloom with over 1,000 species of alpine plants and flowers during summer, including rare endemic species that are nationally protected, and it has long been a treasure trove of medicinal herbs, contributing to traditional Japanese pharmacology.[1][5][2]Culturally, Mount Ibuki holds profound spiritual significance as a sacred site (reiho) worshipped since ancient times, referenced in foundational texts like the Kojiki and Nihon Shoki as a place climbed by the legendary Prince Yamato Takeru during his conquests.[5][2] Some modern interpretations describe it as part of a spiritual alignment connecting major Shinto shrines, such as Ise Jingū and Kumano Hongū Taisha, underscoring its role as a natural barrier and spiritual landmark near the ancient capital of Heijō-kyō (Nara).[5] Geologically, the mountain's limestone composition reveals marine fossils, highlighting its ancient oceanic origins, while its location within Lake Biwa Quasi-National Park enhances its status as a protected biodiversity hotspot.[2]Today, Mount Ibuki attracts hikers and nature enthusiasts via well-maintained trails, such as the route from the Ninth Station Sky Terrace, offering accessible paths with minimal elevation gain for a rewarding summit experience amid seasonal wildflower displays and panoramic views of Lake Biwa to the south.[1]
Geography
Location
Mount Ibuki is situated on the border between Maibara in Shiga Prefecture and Ibigawa in Gifu Prefecture, Japan, forming a natural divide in the central Honshu region.[1][2] This positioning places it within the broader Kinki (Kansai) region, contributing to its accessibility from major urban centers like Nagoya and Kyoto.[6]The mountain's summit is located at 35°25′04″N 136°24′22″E, with an elevation of 1,377 meters, making it the highest peak in Shiga Prefecture.[7][2] As the prominent northern terminus of the Ibuki Mountains—a range that extends southward along the prefectural boundary—it overlooks the Sekigahara Plain at its base, a historically significant lowland known for the pivotal Battle of Sekigahara in 1600.[8][9]To the south, Mount Ibuki lies near the northern fringes of the Suzuka Mountains, connecting it to larger topographic systems in central Japan that influence regional weather and biodiversity patterns.[8]
Topography
Mount Ibuki rises to a summit elevation of 1,377 meters, marking the highest point in Shiga Prefecture.[1] The mountain's elevation profile features steep lower slopes that ascend rapidly from surrounding lowlands around 500 meters, transitioning to gentler gradients and expansive flat grasslands near the summit.[10] This structure creates a dramatic vertical rise of approximately 850 meters over short horizontal distances, contributing to its prominence in the regional landscape.[11]As the principal peak of the Ibuki Mountains, a range straddling the border between Shiga and Gifu prefectures, Mount Ibuki forms part of a broader north-south trending ridge system within the eastern Omi Basin's mountainous periphery.[12] The range lacks major subsidiary peaks comparable in height, allowing unobstructed panoramic views from the summit toward Lake Biwa to the west and the expansive plains of the Nobi region to the north and east.[13]These meadows, covering the higher elevations above the treeline, exhibit minimal permanent water bodies, with vegetation adapted to the rocky and windswept terrain. Seasonal streams emerge primarily from snowmelt in spring, feeding temporary watercourses that carve subtle channels across the slopes.[14]Hydrologically, Mount Ibuki's drainage divides into two main systems: southern slopes contribute to the Yodo River basin via tributaries flowing into Lake Biwa, while northern and eastern aspects drain toward the Kiso River system and the Sekigahara Plain in Gifu Prefecture.[2][12] These seasonal flows, augmented by precipitation and snowmelt percolation through permeable limestone layers, support alluvial fans at the mountain's base and integrate into broader regional river networks.[14]
Geology
Formation
Mount Ibuki originated as part of the Mino terrane, an accretionary complex in central Japan formed through subduction of ancient oceanic lithosphere during the Paleozoic and Mesozoic eras.[15] The mountain's core consists of Permian marine sedimentary rocks, including limestone buildups that developed as carbonate caps atop seamounts in an open-ocean Panthalassic setting, indicative of submarine volcanic origins approximately 299 to 252 million years ago.[16] These formations, characterized by reefal facies with fossils such as fusulinaceans and conodonts, reflect deposition on volcanic edifices within a pelagic environment before accretion to the continental margin.[17]Volcanic activity associated with these submarine structures ceased by the end of the Paleozoic, leaving the rocks to undergo subsequent tectonic incorporation into the evolving Japanese archipelago. During the Miocene epoch, around 23 to 5 million years ago, the region experienced renewed tectonic activity as part of the broader formation of the Japanese volcanic arc, driven by back-arc spreading in the Japan Sea and subduction along the proto-Philippine Sea Plate boundary. This phase integrated the older Mino terrane rocks into the emerging Ibuki Mountains through compressional deformation and initial uplift.The modern landform of Mount Ibuki emerged primarily through Cenozoic tectonic uplift linked to ongoing subduction of the Philippine Sea Plate beneath the Eurasian Plate, with significant elevation gain occurring since the Pliocene, approximately 5 to 2.6 million years ago. Post-uplift shaping has been dominated by erosional processes, including fluvial incision and weathering, which have sculpted the mountain's steep slopes and resulting elevation of 1,377 meters, though detailed topography is further elaborated elsewhere.[18]
Rock Composition
Mount Ibuki's rock composition is dominated by sedimentary rocks from the Paleozoic Mino Belt, with Permian limestone forming the primary lithology in the upper elevations above approximately 900 meters. This limestone, deposited during the Permian period approximately 299 to 252 million years ago, consists mainly of microcrystalline calcite (CaCO₃), originating from biogenic accumulations in ancient coral reef environments on the seafloor.[19][20] The rock exhibits blocky structures with abundant fractures, contributing to high permeability and the development of karst features such as karrenfelds and large outcrops near the summit. Fossils including fusulinids, crinoids, and coral remnants are embedded within the limestone, indicating a marine depositional setting.[20]In the lower elevations, the composition shifts to non-calcareous sedimentary layers, including chert (predominantly microcrystalline quartz, SiO₂), mudstone, and interbedded sandstone-mudstone sequences from the Carboniferous to Early Cretaceous periods. These rocks overlie or are thrust beneath the limestone along structural boundaries and contain fewer calcareous elements compared to the upper formations. Metamorphic influences are minimal, though some areas show coarse-grained crystalline limestone with skarn minerals due to localized intrusions.[18][20]Structurally, the mountain's lithology is shaped by a low-angle thrust fault along the Shiga-Gifu prefectural border, which tilts westward and separates the limestone cap from underlying chert and mudstone layers, creating a dome-like morphology with limited differential erosion. Geological surveys by the Geological Survey of Japan have identified these features through stratigraphic mapping and fossil analysis, confirming the sedimentary overlays from ancient marine environments without significant igneous components in the exposed sections.[21][20]
Climate
Weather Patterns
Mount Ibuki's climate is classified as humid continental (Dfb) under the Köppen-Geiger system, characterized by mild summers and cold winters, with significant moisture influences from winter monsoons originating over the Sea of Japan that enhance precipitation patterns across the region. This classification reflects the temperate conditions typical of central Japan's mountainous areas, where elevation moderates temperatures but amplifies orographic effects on weather.Average annual precipitation in the Mount Ibuki area is approximately 2,000 mm or more, with the majority occurring as summer rainfall from the East Asian monsoon and winter snowfall due to cold frontal systems.[22] Temperatures vary by elevation, ranging from averages of around -5°C during winter months at mid-slopes to 25°C in summer at lower elevations, though summit conditions are cooler, often dropping below -8°C in January lows.[23] These conditions are based on historical records spanning 1961–1990, a standard period for climatological normals established by the World Meteorological Organization, though updated normals (1991–2020) from the Japan Meteorological Agency show slight warming trends in recent decades.[24]Prominent wind patterns include the strong westerly gusts known as Ibuki Oroshi, which descend from the mountain's summit toward the surrounding plains, often reaching significant speeds and fostering distinct microclimates by channeling cold air and exacerbating soil erosion on exposed slopes.[25] This downslope wind, prevalent in winter, contributes to the area's rugged topography and influences local weather variability. One extreme event highlights the potential intensity: on February 14, 1927, Mount Ibuki recorded 230 cm of snowfall in 24 hours, the highest single-day total ever measured globally.[26]
Seasonal Variations
Mount Ibuki exhibits distinct seasonal weather variations, influenced by its location near Lake Biwa, which contributes to lake-effect precipitation, within a general humid continental (Dfb) climate framework. Winters are marked by intense cold and substantial snow cover, while springs bring transitional thawing and renewal, summers offer relatively temperate conditions with moisture, and autumns provide crisp clarity ideal for scenic viewing.In winter, from December to February, heavy snowfall dominates due to moist air masses interacting with the mountain's elevation, leading to accumulations that can reach 2-3 meters in severe seasons.[4] Cold snaps frequently push temperatures below -10°C, with average January lows around -8°C and highs near -3.4°C, creating conditions suitable for snow-based activities.[23] Snowfall is particularly pronounced in January, averaging about 12 cm monthly at mid-elevations, though historical events demonstrate the potential for far greater depths.[27]Spring, spanning March to May, features the gradual snowmelt from winter accumulations, which typically begins in late March as temperatures rise, with March highs averaging 0.6°C and lows -5.3°C.[23] This thawing coincides with moderate rainfall, averaging 150-200 mm monthly, fostering the emergence of alpine wildflowers across the slopes starting in April.[23] By May, highs reach 13.2°C, supporting blooms of species like bamboo lilies and Ibuki toranoo in the summit areas.[28]Summer months from June to August maintain mild temperatures, with August highs averaging 20.9°C and lows 15.9°C, moderated by the mountain's altitude despite surrounding regional heat.[23] High humidity levels, often exceeding 90%, contribute to frequent afternoon thunderstorms, driven by the rainy season's extension into early summer and convective activity.[23]Precipitation totals around 200-250 mm per month, primarily from these storms, keep the environment lush but occasionally disruptive.[23]Autumn, from September to November, brings cooling temperatures and clearer skies, with September highs at 17.1°C dropping to 6.2°C by November, alongside reduced humidity around 83-91%.[23] This period is renowned for vibrant foliage viewing, with peak colors typically occurring in mid-November, as seen in recent observations around 900-meter elevations. Daylight hours shorten to about 10 hours by November, enhancing the vivid display against predominantly sunny conditions.[23]Extreme weather events underscore the mountain's variability, including the world record for 24-hour snowfall of 230 cm on February 14, 1927, resulting in a total depth of 11.82 meters.[4] Temperature records, spanning 1919 to 2001 from Japan Meteorological Agency data, capture historical lows and highs, though these figures may benefit from updates incorporating post-2001 observations to reflect any shifts, such as reduced snowfall due to warming trends observed through 2025.[24] Such extremes highlight the need for monitoring ongoing patterns at this site.
Ecology
Flora
Mount Ibuki's flora is characterized by a rich diversity of alpine and subalpine species, with approximately 1,300 vascular plants recorded across its slopes, representing over half of Shiga Prefecture's total flora.[29] This biodiversity arises from the mountain's varied elevation gradient and exposure to harsh environmental conditions, including persistent strong winds that shape distinct vegetation communities.[2] The lower elevations feature mixed forests, while higher zones transition to open grasslands dominated by herbaceous plants adapted to nutrient-poor, rocky substrates.[30]The summit grasslands, extending above the treeline around 1,000 meters, form expansive flower meadows that host a high diversity of alpine herbs and grasses, many of which are low-growing and wind-resistant to withstand the mountain's notorious gales.[29] These meadows, a designated national scenic site, include subalpine perennials such as Sankayo (Diphylleia grayi) and native dandelions (Taraxacum spp.), which thrive in the thin, limestone-derived soils.[29] The windy conditions referenced in weather patterns limit woody growth, favoring resilient herbaceous communities that bloom vibrantly in summer.[2] Since 2008, restoration efforts by the Mt. Ibukiyama Nature Restoration Council have aimed to manage vegetation, remove invasive alien species like non-native dandelions, and restore flower meadows to their 1970s extent.[29]At lower elevations, from the foothills up to about 700-1,000 meters, dense forests dominate, comprising cool-temperate deciduous broadleaf trees like Siebold's beech (Fagus crenata), Mongolian oak (Quercus mongolica var. grosseserrata), and Japanese horse chestnut (Aesculus turbinata) in riparian and slope areas.[30] Coniferous elements, including Ibuki juniper (Juniperus chinensis var. ibukiana), integrate with these broadleaf stands, creating transitional scrub zones before giving way to subalpine meadows.[30] This zonation reflects the mountain's elevational microclimates, where cooler, moister conditions support mixed woodland habitats.[31]Rare and endemic plants underscore Mount Ibuki's ecological uniqueness, with at least nine species restricted to the summit meadows, such as Ko-ibuki-azami (Cirsium confertissimum), a compact thistle adapted to exposed ridges, and Ruri-toranoo (Pseudolysimachion subsessile), a delicate blue-flowered speedwell.[29] Other protected endemics include Veronica subsessilis and Ibuki-toranoo (Pseudolysimachion subsessile var. ibukiense), alongside quasi-endemics like Cirsium tashiroi and northern relics such as Lysimachia thyrsiflora.[30] Seasonal blooms enhance this diversity, with spring displays of azaleas (Rhododendron spp.) in forested lower slopes and vivid autumn foliage from maples and oaks transforming the landscape.[32]The high endemism on Mount Ibuki stems from its limestone geology and diverse microclimates, which create isolated habitats fostering specialized adaptations among alpine herbs and relic species from cooler climates.[29] These factors, combined with the mountain's position at the convergence of warm and cold floral elements, support a concentration of rare taxa not found elsewhere in central Japan.[30]
Fauna
Mount Ibuki's fauna encompasses a range of mammals, birds, insects, and reptiles adapted to its forested slopes, woodlands, and alpine grasslands. The lower and mid-elevation forested areas support several notable ungulates, including the Japanese serow (Capricornis crispus), a shy, goat-antelope endemic to Japan that browses on understoryvegetation in dense woodlands; wild boar (Sus scrofa), which root through the forest floor for food; and sika deer (Cervus nippon), commonly sighted grazing in mixed forest habitats.[2][33] These mammals contribute to the ecosystem by influencing vegetation structure and seed dispersal, though sika deer populations have overpopulated as of 2024, leading to excessive browsing that damages rare alpine plants and alters habitats.[33]Japanese serow populations face challenges from habitat fragmentation, which limits movement and genetic exchange in mountainous regions like Mount Ibuki.[34]The avifauna is particularly rich, with grassland species such as common cuckoos (Cuculus canorus), Japanese bush warblers (often called nightingales, Horornis diphone), buntings (Emberiza spp.), and Japanese pheasants (Phasianus versicolor) frequenting open areas for nesting and foraging. Woodland habitats host woodpeckers (Dendrocopos spp.), flycatchers (Ficedula spp.), and Eurasian jays (Garrulus glandarius), while the alpine zones provide breeding grounds for raptors like the golden eagle (Aquila chrysaetos), which preys on smaller mammals and birds in the rugged terrain. The area is recognized as an Important Bird Area, supporting both resident and migratory species that utilize the mountain's elevation gradient.[2][35]Insects thrive in the mountain's flower-filled meadows, with a wide diversity of butterflies (Lepidoptera) drawn to nectar sources in the grasslands, including species like the Old World swallowtail (Papilio machaon) observed at higher elevations. Reptiles, such as snakes adapted to open grassy habitats, including rat snakes (Elaphe climacophora), inhabit the lower slopes and meadows, preying on small vertebrates and invertebrates. These invertebrates and reptiles play key roles in pollination and pest control within the ecosystem.[2]Many of these animals depend on the mountain's native plants for food and shelter, integrating animal and plant communities in a cohesive ecological web.[34]
History and Culture
Historical Role
Mount Ibuki has been referenced in ancient Japanese texts from the Nara period, serving as a prominent landmark due to its distinctive shape and perceived spiritual significance. In the Kojiki (712 CE) and Nihon Shoki (720 CE), the mountain is described as the dwelling of a deity, portrayed as a large white boar resembling an ox, which underscores its role as a natural and symbolic boundary in early Japanesegeography.[2] These texts highlight the mountain's visibility and imposing presence, positioning it as a key navigational and cultural reference point along ancient travel paths.[5]Archaeological evidence indicates human presence in the Mount Ibuki region dating back to prehistoric times, with Jōmon-period settlements documented in nearby Lake Biwa through submerged sites containing shell middens, pottery, and tools.[36] Throughout the medieval and early modern periods, the mountain's foothills facilitated vital regional trade routes connecting eastern and western Japan, enabling the exchange of goods such as medicinal herbs and agricultural products without hosting major conflicts on its slopes.[2] Its border location between provinces enhanced its strategic value for overland passage, though no significant battles occurred directly on the mountain.The mountain's historical prominence peaked during the Battle of Sekigahara in 1600, a decisive clash near its base that propelled Tokugawa Ieyasu to power and established the Tokugawa shogunate, ending the Sengoku period.[37] After the Western army's defeat, leader Ishida Mitsunari fled to Mount Ibuki, where he was captured three days later, symbolizing the site's role as a refuge in the conflict's aftermath.[38] In the 20th century, infrastructure developments, including the construction of access roads like the Ibukiyama Driveway, improved connectivity and supported regional economic activities around the mountain.[39]
Cultural Significance
Mount Ibuki has been celebrated in classical Japanese literature, particularly waka poetry, since the Heian period (794–1185), where it is often praised for its striking silhouette and natural beauty. One notable example appears in the Hyakunin Isshu anthology, in a poem by Fujiwara no Sanekata (active late 10th century), which evokes the mountain's mugwort plants burning like unrequited passion: "Even if you say so, / the mugwort of Ibuki / burns alone; / if only my love / would cross over to you." This imagery highlights the mountain's role as a metaphor for emotional intensity in courtly verse, reflecting its prominence in the cultural imagination of the era.In modern times, Mount Ibuki gained further acclaim through Kyūya Fukada's influential 1964 book Nihon Hyakumeizan (100 Famous Japanese Mountains), where it is ranked as the 34th entry, selected for its dramatic isolation, fierce winds, and ecological uniqueness.[40] The peak also features on regional lists, including the 100 Kinki Mountains and the 50 Shiga Mountains, underscoring its enduring status as a landmark of natural and cultural heritage in the Kansai region.[6]Folklore ties Mount Ibuki to divine winds and healing, with its name deriving from "ibuki," meaning a powerful exhalation, alluding to the strong seasonal gusts known as ibuki oroshi that sweep down from its slopes, personified in local traditions as manifestations of wind kami (gods).[25] Ancient texts like the Kojiki and Nihon Shoki mention a resident deity on the mountain, reinforcing its sacred aura as a site of Shugendo ascetic practices blending Shinto and Buddhist elements.[2] Additionally, the mountain is renowned for its medicinal herbs, particularly the "Ibuki three major herbs"—mugwort (Artemisia princeps), angelica (Angelica acutiloba), and cnidium (Cnidium officinale)—gathered since antiquity for traditional remedies in Kampo medicine, with over 280 species identified for their therapeutic properties.[2][41]As a symbol of Shiga Prefecture, Mount Ibuki represents the region's natural majesty, often depicted in promotional media and local iconography as its highest peak and a gateway to alpinebiodiversity.[42] It features in cultural events like the Ibuki-yama TaikoDance, a rain-prayer ritual held at its base in Maibara every five years, where performers in traditional attire drum to honor the mountain's kami, preserving intangible heritage tied to agrarian folklore.[43]
Recreation and Access
Hiking Routes
Mount Ibuki offers accessible hiking options suitable for a range of skill levels, with routes emphasizing the mountain's alpine grasslands and panoramic vistas. The primary route utilizes the Ibukiyama Driveway, a toll road that ascends to an elevation of approximately 1,200 meters near the ninth station, allowing hikers to begin their ascent from a high starting point.[1][44]From the parking area at the end of the Ibukiyama Driveway, the trail to the summit is an easy, beginner-friendly path covering about 1.3 kilometers one way with an elevation gain of roughly 177 meters, typically taking 10 to 20 minutes to reach the 1,377-meter peak. This short hike traverses open grasslands with minimal obstacles, providing immediate access to the broad, flat summit area. Key features include stunning viewpoints overlooking Lake Biwa to the west and the surrounding Shiga and Gifu prefectures, especially clear on fine days.[1][32][13]An alternative trail starts from Ibuki-Tozanguchi at a lower elevation, which would offer a more moderate challenge with a round-trip duration of 4 to 6 hours over approximately 10 kilometers. This route involves steeper sections toward the upper grasslands, requiring steady pacing and basic fitness, with an elevation gain of up to 700 meters depending on the exact path taken. Hikers would encounter forested lower slopes transitioning to exposed alpine terrain, enhancing the sense of accomplishment upon reaching the summit. However, this trail has been closed since July 2023 due to a landslide from heavy rains, and as of November 2025, it remains inaccessible with repairs ongoing; hikers should check official sources for updates on reopening.[13][11][45][33]Due to the closure of the lower trail, the mountain's accessible paths primarily cater to beginners via the upper route from the Driveway. Notable features include seasonal highlights such as vibrant autumn foliage in October and snow-covered hikes in winter, where icy conditions demand caution and proper gear; these variations can intensify the experience but align with the mountain's variable weather patterns.[1][13]
Transportation
Mount Ibuki is accessible via a combination of rail and road networks from nearby urban centers in Japan's Shiga and Gifu prefectures. The primary train access point is JR Sekigahara Station on the Tokaido Main Line, from which seasonal buses operate during summer months to shuttle visitors to the main trailhead at higher elevations. For eastern approaches, Omi-Nagaoka Station on the JR Tokaido Main Line provides an alternative entry, connecting to local roads leading toward the mountain's flanks.By car, travelers can reach Mount Ibuki via the Meishin Expressway, exiting at the Sekigahara Interchange and following Route 365 or other local roads to designated parking areas near the base. These parking lots are situated at elevations between 1,000 and 1,200 meters, facilitating a convenient start to ascents. The journey from major cities like Nagoya or Kyoto typically takes 2 to 3 hours by car or train, making the mountain a feasible day trip destination.Additional public options include seasonal buses departing from Maibara Station, which serve as a direct link for hikers avoiding personal vehicles. Note that the former Ibuki Gondola, which once provided cable car access to the summit area, has been closed since 2011 and is no longer operational. This straightforward transportation infrastructure contributes to the mountain's popularity among day visitors.
Conservation
Protected Status
Mount Ibuki is designated as part of the Biwako Quasi-National Park, a protected area established in 1950 that encompasses the mountain's diverse ecosystems along the border of Shiga and Gifu prefectures.[29] The summit grasslands, renowned for their alpine flora, have been recognized as a National Natural Monument due to their exceptional biodiversity, including over 1,300 plant species and nine endemics.[33][32]Management of the mountain is jointly overseen by Shiga and Gifu prefectures through the Mt. Ibukiyama Nature Restoration Council, which enforces strict regulations to preserve its natural features.[29] These include prohibitions on entering flower fields, collecting plants or insects, and littering, as well as guidelines for staying on designated trails to minimize erosion and disturbance from numerous annual visitors.[9][29]Conservation efforts focus on restoring the mountain's grasslands, which have degraded due to shrub encroachment, invasive species, and reduced traditional hay-making practices since the 1990s. The Shiga Prefecture-initiated Mountain Grassland Restoration Project, launched in 2008, involves local groups in activities such as mowing, fencing sensitive areas, removing non-native plants like dwarf bamboo and alien dandelions, and sowing native herb seeds to revive the flower meadows.[29] Ongoing monitoring targets endemic species, including the Ibuki gentian (Gentiana sp.), through patrols and distribution surveys to track threats like overgrazing by deer.[29]
Recent Events
In July 2023, a severe mudslide triggered by heavy rains struck Mount Ibuki, severely damaging the Ibuki-Tozanguchi hiking trail and leading to its indefinite closure for safety reasons.[46][11] The incident, which experts attribute partly to soil erosion exacerbated by overbrowsing from wild deer populations, has prompted ongoing repair efforts; as of late 2025, the trail remains closed while assessments and repairs continue, with earlier targets for a spring 2025 reopening potentially delayed.[46][33] Local hikers have been advised to use alternative access points, such as the Ibukiyama Driveway, for partial ascents, allowing limited recovery of mountaintop access amid the restrictions.[45]The mountain's infrastructure has seen significant changes in recent years, including the permanent closure of the Ibukiyama Ski Area and its associated gondola lift in 2008, due to declining usage and maintenance costs, leaving the facilities abandoned.[47] Post-landslide, authorities have initiated new trail maintenance initiatives, focusing on stabilization and erosion control along affected routes to mitigate future risks from extreme weather events like the 2023 rains.[11]These developments have influenced tourism patterns, with access restrictions on the primary trail redirecting visitors to secondary paths and drive-up viewpoints, thereby distributing foot traffic and preserving sensitive ecosystems during recovery.[45]Recovery initiatives, including trail repairs and environmental monitoring, have received support from Shiga and Gifu prefectures to restore safe access while addressing broader impacts from intensified extreme weather since the early 2000s.[48]In 2025, Mount Ibuki experienced its autumn foliage peak on November 8, with vibrant colors reaching optimal viewing around the 900-meter elevation on the mountain's slopes.[49]
