Touhou Project
The Touhou Project is a long-running Japanese dōjin series of bullet hell shoot 'em up video games, primarily developed single-handedly by Jun'ya "ZUN" Ōta as the sole member of Team Shanghai Alice.[1][2] The series centers on a fictional fantasy world called Gensokyo, where human protagonists like the shrine maiden Reimu Hakurei and the witch Marisa Kirisame resolve supernatural incidents by battling youkai and other mythical beings through intricate patterns of projectiles known as "danmaku."[1][2] Originating in 1997 with the debut title Highly Responsive to Prayers for the NEC PC-98 platform, the franchise has evolved from early experimental works to a Windows-based mainline series, with ZUN handling all aspects of programming, graphics, writing, and composing the distinctive soundtrack for each entry.[2][3][4] By 2025, it encompasses 20 mainline games, the latest being Touhou Kinjōkyō: Fossilized Wonders, alongside numerous spin-offs in genres like fighting, puzzle, and role-playing, as well as official manga, novels, and music releases distributed through dōjin events such as Comiket and digital platforms.[2][1] ZUN's development philosophy emphasizes creative freedom and a continuous narrative akin to an ongoing manga, prioritizing innovative gameplay and world-building over polished production values, which has sustained the series' niche appeal for three decades.[1][3] A hallmark of the Touhou Project is its expansive fan ecosystem, encouraged by ZUN's lenient yet structured guidelines that permit non-commercial dōjin derivatives—including fan games, music arrangements, art, and animations—provided they do not misuse official assets or imply endorsement.[5] This has fostered a vibrant global community, with Touhou-inspired works proliferating at conventions and online, while official content remains rooted in ZUN's vision of accessible, accomplishment-driven experiences that blend intense action with folklore-inspired storytelling.[1][3] The series' music, often arranged in live performances and albums, further amplifies its cultural impact, drawing players into Gensokyo's lore through melodic themes that underscore boss encounters and atmospheric exploration.[1][6]Games
PC-98 games
The PC-98 games represent the foundational era of the Touhou Project, consisting of five titles developed exclusively for the NEC PC-9801 series of computers by ZUN under the banner of ZUN Soft (later rebranded as Team Shanghai Alice).[7][8] These games were released as doujin (independent) software at events like Comiket, reflecting ZUN's solo development efforts during his time as a college student and early career.[7] The series began as an experimental venture, blending Japanese folklore with action gameplay, and established the core theme of protagonists resolving supernatural "incidents" in a fantastical, Japan-inspired world populated by yokai and mystical beings.[9][10] The first game, Touhou Reiiden ~ The Highly Responsive to Prayers (full release August 15, 1997), marked ZUN's debut in game development and introduced the shrine maiden Reimu Hakurei as the protagonist.[7][11] Unlike later entries, it featured hybrid puzzle-shooter mechanics reminiscent of Breakout, where players controlled a paddle to deflect a ball-like orb against enemies and bosses in non-scrolling stages.[7] The story involves Reimu investigating strange occurrences at the Hakurei Shrine, battling yokai in a haunted setting, with multiple stages and routes culminating in boss fights against figures like Sara (a mysterious crow tengu), Elis (an innocent devil), and Sariel (angel of death).[7][12] The second title, Touhou Fuumaroku ~ The Story of Eastern Wonderland (released August 15, 1997), shifted toward traditional shooting elements, introducing vertical scrolling and the witch Marisa Kirisame as a playable character alongside Reimu.[9] Players select one character for a single-player campaign across six stages, dodging enemy bullets while firing shots, with mechanics including focused and unfocused firing modes and power-up collection.[9] The narrative follows the duo resolving a fairy-induced incident threatening Gensokyo, featuring bosses such as Rika, Meira, and Mima, emphasizing themes of yokai mischief in a sealed fantasy land.[9][13] Touhou Yumejikuu ~ The Phantasmagoria of Dim.Dream (released December 29, 1997), the third installment, pioneered bullet hell patterns with dense, intricate bullet spreads that foreshadowed the series' signature danmaku intensity.[14] This competitive shooter employed a split-screen format for versus-style duels, allowing two players (or one against AI) to battle simultaneously in a tournament-style story mode with branching paths based on match outcomes. Reimu and Marisa return, joined by newcomers like Mima and Yuuka Kazami, as they compete in a dream-world contest to claim a mysterious "Dream Crystal," incorporating early spell-like attack declarations that prefigure the formalized spell card system. Stages include aerial and ground-based arenas with bosses delivering patterned barrages, blending competition and narrative resolution of interdimensional rifts. The fourth game, Touhou Gensoukyou ~ Lotus Land Story (released August 14, 1998), refined the vertical shooter formula with enhanced bullet hell density and introduced active border mechanics for temporary invincibility.[15] Players control Reimu or Marisa (with variations like dream forms) through six stages, collecting items to build power and bombs for screen-clearing attacks, while navigating increasingly complex danmaku patterns. The plot centers on an incident drawing Reimu into a dream world filled with endless cherry blossoms, leading to encounters with bosses such as Orange, Kurumi, Elly, and Yuuka Kazami, reinforcing themes of dream realms and youkai power.[16] Concluding the PC-98 era, Touhou Kaikidan ~ Mystic Square (released December 30, 1998), expanded on prior mechanics with faster pacing, larger hitboxes, and more elaborate stage structures across six levels.[10] Reimu and Marisa team up with Mima and Cirno as playable options, each with unique shot types and bomb abilities, facing off against demons invading from Makai in a story of portal disruptions.[10] Boss fights feature multi-phase patterns, including precursors to spell cards through named attack declarations, with thematic elements drawing on demonic yokai lore and fantasy incursions into Gensokyo.[10] The PC-98 hardware's limitations significantly shaped these games, including 16-color EGA graphics that resulted in simplistic sprites and backgrounds, MIDI-based soundtracks limited to basic chiptune synthesis, and slower processing that influenced deliberate gameplay pacing and fewer on-screen bullets compared to later titles.[8][10] Sales were niche and low, ranging from 30 to 300 copies per title at doujin events, reflecting the platform's declining popularity by the late 1990s.[17][18] Support for PC-98 versions ended on September 19, 2002, paving the way for a transition to the Windows platform for greater accessibility and refined mechanics.[8]Windows games
The Windows era of the Touhou Project began with Embodiment of Scarlet Devil (Touhou 6), released on August 11, 2002, marking the transition from PC-98 hardware to modern Windows platforms and enabling higher-resolution graphics and more intricate MIDI-based music compositions by ZUN. This title introduced the spell card rules, a formalized system where bosses declare named danmaku patterns with time limits, balancing intensity and fairness in bullet hell encounters while emphasizing aesthetic bullet patterns over pure destruction.[19][20] The game features six stages with escalating danmaku density, playable characters Reimu Hakurei and Marisa Kirisame, and an extra stage, establishing the series' core vertical-scrolling shooter format that became a staple. Subsequent mainline entries built on this foundation, evolving mechanics and themes. Perfect Cherry Blossom (Touhou 7, 2003) expanded scoring with boundary mechanics, while Imperishable Night (Touhou 8, released August 15, 2004) innovated with a partner system, allowing players to switch between a human and youkai teammate for complementary shot types and time-manipulation scoring during a nighttime incident.[21] Phantasmagoria of Flower View (Touhou 9, 2005) shifted to a versus-style shooter, but the series returned to solo danmaku with Mountain of Faith (Touhou 10, August 17, 2007), incorporating seasonal autumn themes through leaf-based enemies and faith-gathering mechanics via item collection to power up shots.[22] Later titles like Subterranean Animism (Touhou 11, 2008) and Undefined Fantastic Object (Touhou 12, 2009) refined stage variety and boss designs, with the former reusing the partner system and the latter adding UFO collection for scoring bonuses. The series continued its progression through the 2010s, with Ten Desires (Touhou 13, 2011) emphasizing trance mechanics for temporary power boosts and Double Dealing Character (Touhou 14, August 12, 2013) introducing weapon-changing via absorbed projectiles, resolving an incident tied to tool-using youkai. Legacy of Lunatic Kingdom (Touhou 15, August 14, 2015) featured lunar invasion themes with evasion-focused scoring and pointdevice mode for practice.[23] Hidden Star in Four Seasons (Touhou 16, August 12, 2017) introduced season-changing mechanics through collected orbs, set during a bizarre winter extending into spring. Wily Beast and Weakest Creature (Touhou 17, August 12, 2019), centered on beast youkai spirits invading Gensokyo, with animal companion shot types for Reimu, Marisa, and Sanae; Unconnected Marketeers (Touhou 18, May 4, 2021), incorporating ability card collection from mid-bosses to purchase power-ups like homing shots or speed adjustments between stages; and Unfinished Dream of All Living Ghost (Touhou 19, October 27, 2023), a unique board game-style shooter where players bid on and control vengeful ghosts to resolve an incident.[24][25] The latest mainline entry, Touhou Kinjōkyō ~ Fossilized Wonders (Touhou 20), was announced on April 12, 2025, with a trial demo released at Reitaisai 22 on May 5, 2025, and the full version launching on August 17, 2025, at Comiket 106. This bullet hell game revolves around an incident involving eight collectible "incident stones" powered by past Gensokyo events, which players use to summon themed enemies and alter shot types, featuring Reimu and Marisa as protagonists in a format blending collection and traditional danmaku resolution.[2][26][27]| Title | Number | Release Date | Key Innovation |
