Yuki Chiba
Yuki Chiba (千葉雄喜, Chiba Yūki; born April 22, 1990) is a Japanese rapper, singer, and songwriter, formerly performing under the stage name KOHH from 2008 to 2023.[1][2] Born and raised in the Oji neighborhood of Kita, Tokyo, Chiba emerged in the underground hip-hop scene with mixtapes addressing urban struggles, drug use, and violence—topics often taboo in Japanese society.[1][3] His breakthrough came with the 2014 album Monochrome, praised for its raw authenticity and establishing him as a key figure in Japanese hip-hop.[1] Chiba gained international attention through collaborations, including a feature on Frank Ocean's extended "Nikes" from the 2016 Boys Don't Cry release and a verse on Megan Thee Stallion's 2024 single "Mamushi," which peaked at number 36 on the Billboard Hot 100 and led to a joint performance at the MTV Video Music Awards.[4][5] In 2024, he relaunched under his real name, retired KOHH-era songs from live sets amid scrutiny over their explicit content, and signed with Warner Music Japan and 300 Entertainment.[6][7]Early life
Family background and upbringing
Yuki Chiba was born on April 22, 1990, in Oji, a district in Kita Ward, northern Tokyo, Japan, to a Korean father and Japanese mother, making him of mixed Korean-Japanese descent.[8] [9] His father's surname, Ko (고 in Korean), later inspired Chiba's stage name KOHH.[2] [10] Chiba's father died by suicide while under the influence of drugs during his childhood, leaving the family without paternal support.[11] [12] [13] His mother, who struggled with methamphetamine addiction, raised Chiba and his younger brother—later known as the rapper Lil KOHH—primarily on her own in a public housing project amid conditions of poverty and neighborhood instability.[11] [14] [1] The family's circumstances exposed Chiba to early adversity, including exposure to drug use in the home and the socioeconomic challenges of a low-income area in Tokyo associated with limited opportunities and social marginalization.[11] [15] [12] These experiences, corroborated across multiple artist profiles and interviews, contributed to a formative environment of hardship that influenced his later reflections on resilience and urban struggle.[1] [14]Initial musical influences and entry into hip hop
Chiba's entry into hip hop was shaped by a turbulent upbringing in Tokyo's Oji district, where he navigated poverty, familial suicide, and early drug exposure amid his mother's methamphetamine addiction. Born on April 22, 1990, to a Korean father and Japanese mother, he grew up in public housing projects characterized by violence and substance abuse, experiences that later informed his raw, autobiographical lyricism as an outlet for personal catharsis.[16][14][11] His musical influences spanned Japanese and Western artists, blending hip-hop pioneers with punk and rock sensibilities. Chiba cited the politically charged Japanese rap group King Giddra for its socially conscious style, alongside Kanye West's innovative production and persona; he also drew from grunge and punk acts including Nirvana, The Blue Hearts—a seminal Japanese punk band—and the Sex Pistols, reflecting a broader rejection of conventional norms that resonated with his lived realities.[11] At age 18 in 2008, Chiba began self-producing tracks, adopting the stage name KOHH to honor his deceased father, and initially operated without formal affiliations in Japan's nascent underground scene.[14] He debuted publicly with the mixtape YELLOW T△PE on November 2012, comprising freestyles, covers, and early collaborations that captured his unpolished, genre-defying approach.[16] This was followed by YELLOW TAPE 2 in August 2013, solidifying his presence among niche hip-hop listeners through themes of street life and addiction.[16][11]Career
Beginnings as KOHH (2010–2015)
Chiba adopted the stage name KOHH in the early 2010s, drawing from his late father's name, and began self-producing and recording tracks while collaborating with emerging artists in Tokyo's underground hip hop scene.[14] He released his debut mixtape Yellow Tape on November 28, 2012, compiling freestyles, covers, and features with rappers such as Loota.[11][3] The project included "Young Forever," a track produced by KOHH and performed by his younger brother Lil KOHH, which achieved viral popularity online and marked an early breakthrough for the duo.[17] Building on this momentum, KOHH issued his second mixtape Yellow Tape 2 on August 31, 2013, continuing to showcase raw production and collaborations within Japan's nascent trap-influenced rap circuit.[3] Around this period, he partnered with producer 318, whose beats elevated KOHH's sound toward more polished trap elements, facilitating formal releases under Gunsmith Production.[3] In July 2014, KOHH dropped his debut studio album Monochrome on July 30, featuring 12 tracks that blended introspective lyrics with aggressive flows, earning notice for its departure from mainstream J-pop toward gritty hip hop authenticity.[18] By 2015, KOHH expanded his output with Yellow Tape 3 on June 30, followed by the album Dirt on October 28, the latter incorporating international recording sessions in London and Paris for tracks like "Dirt Boys" with Dutch Montana and Loota.[3][16] These releases solidified his reputation in Japan's indie rap underground, emphasizing self-taught production and themes of street life, though commercial distribution remained limited to digital and small-label physical formats.[19]Rise to prominence and international exposure (2016–2019)
KOHH released his album DIRT II on June 17, 2016, comprising two discs with collaborations involving international artists and producers, which broadened his appeal within Japan's underground hip hop scene.[20] The project emphasized trap elements and global influences, contributing to his growing domestic recognition.[21] In August 2016, KOHH secured substantial international exposure via his feature on the extended version of Frank Ocean's "Nikes," included in the physical CD bundled with the Boys Don't Cry magazine accompanying Ocean's Blonde album; his Japanese-language verse appeared in the track's final minute.[22] This high-profile collaboration with the American artist introduced KOHH to Western listeners, marking a pivotal moment for his global visibility.[23] Building on this momentum, KOHH issued the Yellow Tape 3 mixtape in 2017, featuring tracks like "Paris" that further showcased his production and lyrical style.[24] That year, he conducted the KOHH LIVE'17 domestic tour, performing in cities including Tokyo.[25] In 2018, he expanded internationally with his U.S. live debut at 88rising's Head in the Clouds festival on September 22 in Los Angeles.[26] KOHH capped the period with the unannounced release of Untitled on February 9, 2019, a 10-track album exploring experimental sounds without prior promotion, which garnered attention for its abrupt drop and stylistic shifts.[27][28] These releases and performances elevated his status in Japanese hip hop while fostering overseas interest through key associations and events.[29]Rebranding to Yuki Chiba and stylistic evolution (2020–2023)
In 2020, while still performing as KOHH, Chiba released worst on April 29 as the concluding installment of the worst Complete Box set, featuring tracks that reflected a raw, introspective turn amid ongoing personal challenges.[30] This project, paired with his final concert appearance at the BADASSVIBES event, signaled the winding down of the KOHH era, though no explicit retirement announcement followed immediately.[30] By the end of 2021, Chiba formally retired the KOHH pseudonym, adopting his birth name Yuki Chiba to align his public identity more closely with his personal self.[4] This rebranding coincided with a deliberate step back from the high-energy, persona-driven hip-hop style associated with KOHH, allowing for a reevaluation of his artistic direction amid a period of relative inactivity in major releases.[6] The shift emphasized authenticity over stage fabrication, as Chiba later indicated through actions like phasing out performances of pre-2022 material to focus on evolved expressions.[6] From 2022 to 2023, Chiba's output remained sparse, with no full-length albums under the new name, marking a transitional phase of stylistic maturation toward genre-blending experimentation and less reliance on traditional rap aggression.[31] This evolution manifested in a broader sonic palette, incorporating elements of alternative and introspective production that distanced from KOHH's trap-influenced bravado, prioritizing matured lyrical depth and boundary-pushing arrangements in subsequent works.[31] The period underscored a causal pivot from commercial momentum to personal reinvention, evidenced by Chiba's immersion in fashion and non-musical pursuits, which informed a more versatile, identity-rooted artistry.[31]Global expansion and recent projects (2024–present)
Chiba resumed his music career on February 12, 2024, releasing the single "Team Tomodachi," which achieved viral success and spawned numerous international remixes by artists from China, Malaysia, and other regions.[32][33] The track's global reach marked a significant step in Chiba's expansion beyond Japan, with remixes highlighting collaborations across Asia and contributing to broader recognition of Japanese rap internationally.[5] In November 2024, Chiba released the single "Dareda?" accompanied by a music video filmed in New York City around his appearance at the MTV Video Music Awards, further emphasizing his growing international presence.[34] Later in December 2024, Chiba issued his first full-length album under the Yuki Chiba moniker, Star, a 13-track project featuring production from GRAMMY-winning collaborators and solidifying his stylistic evolution.[5] The album followed the breakthrough of "Mamushi," cited as Chiba's inaugural global chart hit, which propelled Japanese rap's visibility worldwide.[5] In May 2024, Chiba released Team Friends The Remixes, featuring contributions from eight artists including DJ RYOW, Jin Dogg, and SKY-HI, some of whom later joined as guests for his announced headline concert at Tokyo's Nippon Budokan in July 2025.[35] Transitioning into 2025, Chiba signed a recording deal with Warner Music Japan in partnership with 300 Entertainment on August 29, 2025, aimed at accelerating his international career, including plans to relocate to Los Angeles.[36][37] This agreement facilitated his first U.S. headline concert on September 18, 2025, at The Wiltern in Los Angeles.[36] Musically, he dropped the single "Kibo" on March 26, 2025, alongside an associated album release, maintaining his laid-back lyrical approach.[38] In September 2025, Chiba debuted the improvised blues project Indigo Blue with pianist Ryo Takaiwa under the alias Nijiz, exploring roots-oriented sounds in a full-length album.[39]
Musical style and artistry
Key influences and production techniques
Chiba's key musical influences encompass a blend of hip hop, punk, and rock from both Japanese and Western traditions. He has explicitly cited the pioneering Japanese hip hop collective King Giddra for its socially conscious lyricism, alongside Kanye West's innovative production and persona.[11] Rock influences include Nirvana's grunge intensity, the Sex Pistols' anarchic punk energy, and The Blue Hearts' raw Japanese punk ethos, reflecting a broader draw to rebellious and emotive sounds beyond conventional rap.[11] Personal experiences from a challenging upbringing in Tokyo's Kita ward, including poverty and familial loss, further shape his thematic foundations, while conceptual inspirations from surrealist artists like René Magritte and Dadaist Marcel Duchamp inform his artistic worldview and lyrical abstraction.[14] Early production techniques under the KOHH moniker centered on self-initiated creation starting at age 18, yielding raw trap-infused tracks with heavy 808 bass, rapid hi-hat rolls, and minimalistic arrangements that prioritized atmospheric grit over polished complexity.[1] Chiba integrated punk and rock elements, such as sludgy metal guitar riffs and distorted, Marilyn Manson-like vocals, to disrupt standard trap formulas, as evident in tracks like "Die Young."[11] This organic evolution emphasized subjective lyric delivery over rigid structure, with Chiba noting shifts in sound "just came quite naturally."[11] Post-rebranding, production evolved toward genre experimentation, fusing hip hop with R&B melodies, electronic textures, and introspective layering to achieve mature versatility, as seen in albums like MONOCHROME (2014).[1] Collaborations with trap specialists, such as Murda Beatz on "Maybach," amplify booming, arena-ready beats with relentless percussion and spatial chants, maintaining Chiba's core emphasis on authenticity derived from lived realism.[40]Lyrical themes and persona
Chiba's lyrical content frequently draws from his personal experiences of hardship, including a childhood in Tokyo's Oji district amid familial dysfunction—such as his father's suicide and his mother's methamphetamine addiction—infusing his work with themes of resilience, poverty, and urban survival.[11][1] Early tracks under the KOHH moniker emphasize raw depictions of street violence, drug culture, and authentic roots, as in "Dirt Boys," where he rejects external judgments to affirm his origins.[11] Over time, his themes evolved toward introspection, incorporating existential reflections on art and mortality, evident in songs like "Business and Art" and "If I Die Tonight," which invoke phrases such as "art is long, life is short" to grapple with creativity's permanence against life's brevity.[11] Recurring motifs of financial ambition and stardom persist, particularly in post-rebranding works like "Mamushi," where lyrics celebrate wealth accumulation as a marker of success, echoing earlier KOHH-era tracks on hustling.[41] Broader explorations include love, loss, friendship, personal growth, and societal pressures, often conveyed through sincere, unfiltered narratives that resonate with Tokyo's realities.[1][42] Chiba's persona embodies authenticity and duality: a stage presence marked by aggressive flows and deep-voiced intensity contrasts with off-stage humility and enigma, prioritizing human vulnerability over national or stylistic labels.[11][42] This evolution from gritty defiance to mature introspection underscores a resilient identity shaped by adversity, positioning him as a candid voice in Japanese hip hop that favors emotional depth over polished convention.[1]Reception and impact
Critical assessments
Chiba's early work as KOHH garnered significant praise within Japan's underground hip hop community for its authentic portrayal of urban struggles and fusion of American trap aesthetics with Japanese lyricism. The 2014 album Monochrome achieved massive positive reception, establishing him as a key innovator by blending melancholic introspection with straightforward, childlike enunciation in Japanese, setting it apart from contemporaries.[14][43] Similarly, Dirt (2015) was commended for its aggressive, fun trap elements, brilliant production, and moody, angsty rap style that elevated it above typical releases in the genre.[44][45] Post-rebranding to Yuki Chiba, critical attention has been more limited from major international outlets, though his contributions to tracks like "It G Ma" (2022) and "Mamushi" (2024) have been highlighted for expanding Japanese rap's global reach, with lyrics noted for their loaded simplicity conveying resilience and cultural specificity.[5] However, recent solo projects have elicited mixed user-driven critiques, often contrasting them unfavorably with prior output. The 2024 album STAR, for instance, has been described as competent in eccentric flows and catchy hooks but disappointing overall, failing to match the quality of earlier KOHH material or even Chiba's advertisement compositions, with some reviewers citing a lack of energy and innovation.[46] Aggregated scores reflect this sentiment, averaging around 2.65 out of 5 on platforms tracking enthusiast feedback.[47] Earlier post-rebrand efforts like Worst have similarly been viewed as weaker, struggling to produce standout tracks for repeated listens compared to albums such as Untitled.[48]Commercial achievements
Yuki Chiba's early releases under the moniker KOHH achieved modest international charting but limited mainstream commercial penetration in Japan, with the 2016 mixtape Dirt II (Side A) peaking at No. 14 on Billboard's World Albums chart.[49] Prior to his 2020 rebranding, Chiba's work remained primarily underground, garnering cult followings through digital platforms rather than high-volume physical or Oricon-ranked sales.[49] Chiba's commercial breakthrough occurred in 2024 with his featured verse on Megan Thee Stallion's "Mamushi," from her album Megan, which debuted at No. 77 on the Billboard Hot 100—marking his first entry on that chart—and later peaked at No. 36.[49][50] The track topped the World Digital Song Sales chart, Chiba's first No. 1 there, and amassed over 500,000 units sold in the U.S. by August 2024, driven by viral TikTok trends and streaming.[49][51] It also reached No. 1 on the Rhythmic Airplay chart in October 2024, reflecting sustained radio play.[52] By mid-2025, "Mamushi" had exceeded 284 million Spotify streams globally.[37] This success facilitated Chiba's signing to Warner Music in partnership with 300 Entertainment in August 2025, positioning him for expanded international distribution and touring.[37][36] The collaboration's viral momentum, including performances at the 2024 MTV Video Music Awards, underscored Chiba's transition from niche hip-hop artist to globally viable act.[53]Cultural influence on Japanese hip hop
Yuki Chiba, performing under the moniker KOHH until 2020, played a seminal role in mainstreaming trap-influenced hip hop within Japan, particularly through his 2015 collaboration on the track "It G Ma" with the Marianas Trench, which garnered over 100 million YouTube views by blending Korean and Japanese trap aesthetics with raw, multilingual verses.[54] This viral success challenged the dominance of J-pop and enka in domestic charts, encouraging labels to invest in hip hop acts and fostering a subculture where artists prioritized authentic storytelling over sanitized commercialism.[14] Chiba's emphasis on gritty, autobiographical narratives—rooted in his Tokyo upbringing amid poverty and drug exposure—introduced a level of street realism rare in Japanese rap, where performers historically avoided overt gangsta tropes to evade social stigma.[55] By 2017, outlets described him as a pioneer whose dexterity in fusing local dialects with global trap production re-energized the genre's renaissance, inspiring contemporaries to experiment with subgenres like drill and grime.[11][56] His 2016 feature on Frank Ocean's "Nikes" extended this influence internationally, exposing Japanese hip hop to Western audiences and prompting domestic artists to seek cross-cultural collaborations, as evidenced by the subsequent rise of acts like Awich and OZworld who adopted similar hybrid styles.[22] Post-rebranding, Chiba's 2024 output continued this trajectory, with simple yet resonant lyrics influencing a shift toward identity-driven rap over mere imitation of American models, broadening the genre's appeal among youth.[5] Beyond music, Chiba's fashion-forward persona—marked by luxury streetwear and unapologetic individualism—permeated Japanese youth culture, correlating with increased hip hop festival attendance from 50,000 in 2015 to over 200,000 by 2023, and enabling underground talents to transition to major-label deals.[1][57]Controversies
2018 personal scandal
In January 2018, a graphic video surfaced online depicting rapper KOHH (Yuki Chiba) performing oral sex on model Ayana Miyamoto, leading to significant public backlash. The footage, captured on a mobile phone, was accidentally uploaded to Miyamoto's Instagram account on January 8, where it showed KOHH identifiable by his distinctive tattoos engaging in the act while Miyamoto filmed.[58][59] Followers quickly recognized the participants, prompting the video's rapid spread across social media platforms and Japanese forums, where it ignited widespread criticism for its explicit nature and the perceived recklessness of the post.[60][61] The incident, involving the then-27-year-old KOHH and 26-year-old Miyamoto, was described in Japanese media as a major scandal ("スキャンダル"), with discussions centering on privacy violations and the appropriateness of sharing such content. Miyamoto's Instagram story was deleted shortly after the upload, but screenshots and reposts proliferated, amplifying the controversy.[59][62] KOHH did not issue a public statement addressing the leak, and no legal actions were reported stemming from the event, though it drew attention to his personal life amid his rising prominence in Japanese hip-hop.[58] The scandal highlighted tensions between celebrity privacy and digital oversharing but had limited long-term impact on KOHH's career trajectory.[60]Retirement of early material and industry critiques
In May 2024, Yuki Chiba announced on the radio program Zeebra’s LUNCHTIME BRAKES that he would retire songs from his KOHH era—his primary output from the early 2010s to 2021—from future live performances, stating unequivocally, “I won’t. KOHH is no more.”[6] This decision followed his 2021 retirement of the KOHH stage name in favor of performing under his birth name, signaling a deliberate separation from earlier material associated with that persona, which often featured raw, trap-influenced tracks reflecting his Tokyo upbringing amid violence and addiction.[6] While the songs remain available on streaming platforms, Chiba's move underscores a focus on evolving artistry, as evidenced by his 2024 releases like “Team Tomodachi,” which marked his return without reliance on past catalog.[6] Chiba has voiced pointed critiques of the Japanese music industry, particularly its marginalization of hip hop. In a Vice Japan interview discussed in a 2015 PRI report, he lamented the scene's small scale, noting its lack of visibility on mainstream television despite growing underground momentum.[55] He highlighted how major broadcasters neglected hip hop, limiting its cultural penetration beyond niche audiences and hindering broader commercial viability. These observations, made during KOHH's rise, reflect frustration with structural barriers in Japan's entertainment ecosystem, where hip hop competed against dominant J-pop and idol genres for airtime and promotion. Chiba's later career trajectory, including independent mixtapes and international collaborations, can be seen as a response to such constraints, prioritizing artistic autonomy over industry conformity.Discography
Studio albums
Yuki Chiba's early studio albums were released under the stage name KOHH through Gunsmith Productions. His debut, Monochrome, appeared on July 30, 2014, featuring 12 tracks blending trap influences with introspective lyrics.[3] Subsequent releases included Kuchinashi in early 2015, emphasizing raw production and personal narratives, followed by Dirt on October 28, 2015, which incorporated grittier beats and collaborations.[63] Dirt II, issued in 2016 and split into Side A and Side B editions, expanded on these themes with extended runtime and experimental elements.[63][64] Later KOHH-era albums comprised Untitled in 2019 and worst on April 29, 2020, the latter marking his highest-charting effort to date with 15 tracks exploring maturity and industry fatigue.[24] After retiring the KOHH persona in 2022 amid personal scandals and critiques of his early work, Chiba resumed under his birth name with solo projects in 2025. These included the debut STAR, followed by Okuman Choja (16 tracks reflecting wealth and introspection), and Eien on June 18, 2025, positioned as his third solo studio album.[65][66][67][68]Mixtapes and EPs
Chiba began releasing mixtapes under the moniker KOHH with YELLOW T△PE on November 28, 2012, a 16-track project that established his trap-influenced style drawing from American hip hop influences.[69][70] The follow-up, YELLOW T△PE 2, arrived on August 31, 2013, expanding on raw, street-oriented lyricism with additional features and production.[30][3] The series continued with YELLOW TAPE 3 on June 30, 2015, incorporating more experimental elements and collaborations, followed by Yellow Tape 4 in 2016 as a CD mixtape release.[71][3][72] YELLOW TAPE 5 concluded the primary run on July 18, 2021, reflecting matured production amid Chiba's evolving career.[24] Additional mixtapes include Dirt, issued in 2015 with 13 tracks emphasizing gritty narratives, and its sequel Dirt II on June 17, 2016, structured as a double-disc effort split into Side A (international collaborations) and Side B (Japanese-focused tracks).[73][64][21] The Lost Tapes, a compilation-style mixtape of unreleased material, surfaced on September 25, 2022.[24][74] Among EPs, Monochrome was released on July 30, 2014, featuring tracks like "Fuck Swag" produced by collaborators such as 夢幻SQUAD.[75] 梔子 (Jasmine) followed as another EP with self-produced elements including "飛行機" and "iPhone 5."[75]Singles
