Kan a.k.a. GAMI English artist profile card about MSC, UMB, 9SARI and Kan Kitchen
Original HIPHOPCs typography card for the English Kan a.k.a. GAMI artist profile.

Kan a.k.a. GAMI has spent more than two decades making Shinjuku audible.

He led MSC from the early-2000s records Teito Hokai and Matador, won an MC battle at B BOY PARK, released solo albums, helped start ULTIMATE MC BATTLE (UMB), built 9SARI GROUP and later turned a kitchen into one of Japanese rap’s most unusual interview spaces.

That list can make him look like several different people: a hard-core street rapper, a battle MC, a label operator, a television personality and a YouTube host. His career makes more sense when those roles are read as one practice.

Kan’s defining work has been to enter a space, challenge its terms and then build another entrance for the people coming after him.

That is why his results matter even when he loses. On August 11, 2026, Kan and DABO exited BATTLE SUMMIT III in the first round against MC TYSON and YOU THUG. The defeat should not be converted into a triumph. The meaningful fact is that a rapper who objected to the battle formats around him two decades earlier—and helped establish a national alternative—was still willing to return as a competitor at K-Arena Yokohama.

Born in Niigata, raised inside Shinjuku

Kan’s birthplace and the place that formed his rap are not the same claim.

In a roundtable published by Young Champion, Kan said he was born in Niigata, lived around Takadanobaba from about age three and regarded North Shinjuku’s third and fourth districts as home from middle school. (Young Champion interview, in Japanese)

This first-person account does not identify a city in Niigata Prefecture. HIPHOPCs therefore does not repeat the more specific “Nagaoka” attribution found on some profile pages.

Shinjuku, by contrast, is documented across the work itself. MS CRU’s first EP is tied to North Shinjuku. Kan later opened an office, studio and cafe in Shinjuku. Kan Kitchen Fes occupied Cine City Square in Kabukicho in 2024. The geography is not a decorative origin story; it is the scale at which his records, organizations and public events meet.

The same distinction governs HIPHOPCs’ Tokyo Rap Atlas: Kan belongs on the Tokyo map because his upbringing and long-running base are documented in Shinjuku, not because Niigata has been erased from his biography.

MSC: a crew before a historical category

MSC began as MS CRU around 2000. Its early path ran through a self-produced demo CD-R, M.S.C.D.001, and a contribution to homebrewer’s vol.1, a compilation connected to the Japanese hip-hop magazine blast. P-VINE’s materials for the 2026 vinyl reissues document that route and list five members: KAN, TA-BOO, PRIMAL, O2 and GO a.k.a. G-PRINCE. (P-VINE reissue announcement, in Japanese)

The 2002 EP Teito Hokai appeared under the MS CRU name. The group then used MSC for the 2003 album Matador. The name change should not obscure the continuity: the same Shinjuku-based voices moved from circulated demos and magazine networks into a catalog that P-VINE could press on vinyl more than twenty years later.

Teito Hokai is often translated as “Collapse of the Imperial Capital.” That English gloss is useful, but it is not an official English release title. The original title is retained here.

MSC’s importance lies partly in perspective. The records do not describe Tokyo from a postcard center. North Shinjuku, Kabukicho, housing, policing and street economies become lived coordinates rather than atmosphere. Kan’s heavy delivery is the most immediately recognizable voice, but the group format matters: one district is heard through several accounts, not reduced to a single narrator.

The 2026 reissues also reveal how the network formed. Matador includes Shibito and DJ BAKU; the earlier EP preserves “Gen’ei,” a track that remains part of discussions of Kan’s early battle-era conflicts. A catalog once treated as present-tense street documentation now functions as a historical source.

Why UMB began with dissatisfaction, not expansion

Kan’s battle history is often compressed into two statements: he won at B BOY PARK in 2002, and he helped establish ULTIMATE MC BATTLE in 2005. The important part is what happened between them.

Aesthetic dissatisfaction was not the whole story. In a 2018 broadcast conversation with Utamaru, Kan recalled that B BOY PARK had ended amid a dispute and that word spread that the next edition might not happen; he identified that break as the starting point for Odamari! Rap Dojo. (Transcript of the broadcast conversation, in Japanese) The 2016 Intellectual Property High Court judgment records the more specific account—that judging failures disrupted the 2003 battle—as Kusari GROUP’s argument, not as a judicial finding. The distinction matters.

In a 2023 conversation with KEN THE 390, Kan described feeling that the battle styles he encountered at Funky Grammar events and B BOY PARK had already developed recognizable forms. He respected their technique but wanted a freer kind of confrontation. He contrasted those formats with the “guerrilla mic” practice around MSC, Mousouzoku and KEMUI’s earlier group OBORO: rappers taking over an open microphone or even another act’s performance to insist on their own skill. (Music Natalie interview, part one, in Japanese)

The point is not that one side was “real” and the other was false. It is that Kan had won inside an existing system and still found its terms insufficient.

The companion interview separates two milestones: MSC members including Kan and staff member MUSSO started Odamari! Rap Dojo in 2004; it developed into ULTIMATE MC BATTLE in 2005. It also identifies the move from open time limits to alternating, fixed-bar turns as a central design change. This profile therefore does not use 2004 and 2005 as competing launch dates. (Music Natalie interview, part two, in Japanese)

The court did independently find that Kan held two predecessor events and five UMB-named qualifiers in 2004–2005, and that he devised the judging system and the UMB name. UMB was therefore both an aesthetic counterproposal to established battle forms and an institutional answer to a tournament route and judging process that had broken down.

UMB’s own 2006 official weblog says the first 2005 tour ran five qualifiers across Osaka and Tokyo and drew more than 500 entries. The later regional network widened the route to the final, but the sources do not prove that one aesthetic objection alone caused every stage of that expansion. When rechecked on August 25, 2026, the UMB homepage still foregrounded its 2024 championship and qualifier notices, so it is treated here as an archive and status snapshot—not as proof of a current 2026 calendar. Participant counts and rules varied by year.

The records disagree on the first year’s scale. The 2016 court judgment lists 16 regional qualifiers and more than 500 entrants for 2005. The 2006 organizer weblog instead describes five Osaka and Tokyo qualifiers in 2005 and presents nationwide expansion as that year’s plan. No source reviewed here establishes whether the two records count “qualifiers” on the same basis. This profile therefore preserves both figures with their provenance rather than combining them.

His appearance as one of the first “monsters” on TV Asahi’s Freestyle Dungeon in 2015 is easier to understand from this angle. Television did not introduce Kan to battle culture. It moved a sensibility shaped by guerrilla microphones and a decade of tournament administration into a mass-audience format.

UMB and KING OF KINGS are separate institutions

Kan’s organizational history contains a distinction that short biographies often blur.

UMB was established while he was affiliated with Libra Records. After moving his release activity onto the Kusari/9SARI route, he developed another tournament on that side. Its first final, held at Shinjuku ReNY on September 23, 2015, used the name “UMB 2015 GRAND CHAMPIONSHIP FINAL.” The official archive and later coverage use “KING OF KINGS 2016 GRAND CHAMPIONSHIP FINAL” for the following edition. (Qetic on the 2015 final / MC Battle Channel’s KOK history)

The record confirms a change in name. It does not, by itself, prove the motive for that change. This profile therefore does not invent one.

UMB and KING OF KINGS maintain separate official sites and histories. Saying that Kan “owns UMB” in the present tense would be misleading. Saying that he helped create UMB and later built a separate tournament through 9SARI preserves both parts of the history.

There is also a legal result behind that separation. Kusari GROUP applied for and obtained registration of a UMB-like mark in 2014. Libra opposed it, and the Japan Patent Office cancelled the registration in January 2016. Kusari sued to reverse that decision; on August 10, 2016, the Intellectual Property High Court dismissed its claim. (Full judgment, in Japanese)

The court recognized Kan’s role in launching the precursor and devising the judging system and UMB name. It nevertheless found that continuous use from around 2006 had made the UMB mark widely recognized as identifying Libra’s tournament business. It also found that Kusari’s unannounced application and use of the similar mark for a separate event had an improper purpose: free-riding on that goodwill and harming Libra’s DVD sales. The mark therefore fell under Article 4(1)(19) of Japan’s Trademark Act. The holding did not erase Kan’s founding contribution; it decided whose business the mark represented when Kusari filed and whether that registration should stand.

This separation also exposes a basic limit of institution-building: a founding role and present-day operation are different facts. Kan answered the separation by creating another name and another route rather than leaving tournament culture behind.

In 2018, he entered Sengoku MC BATTLE’s 18th chapter and defeated Ryofu Karma in the final. The organizer recorded him as the winner and announced a ¥1 million prize. (Sengoku MC BATTLE’s official result) A tournament builder was still willing to submit himself to someone else’s bracket.

9SARI: controlling release routes without collapsing every role

The dates split by function. A 2016 Intellectual Property High Court judgment, in Japanese, records the company’s position that Kan formed Kusari GROUP in 2011. Mikiki’s 2014 history describes Kusari GROUP as a label established in 2012. Corporate formation and the start of label activity are different claims; this profile records both years and does not invent an exact day.

BLACK SWAN was not Kan’s creation. A&R Sho Sato founded the label in 2011 and died in March 2014. Kan decided to preserve BLACK SWAN inside the 9SARI structure and invited DARTHREIDER to become its representative and an artist on the label. The two labels shared the West Waseda office and studio while retaining different identities. (Mikiki’s 2014 label history / DARTHREIDER’s first-person announcement)

These names should not be treated as interchangeable. MSC is a crew. Libra Records is a former label affiliation. 9SARI GROUP and BLACK SWAN are label or platform projects. Kusari Group is a company. A distributor that carries a release is not automatically Kan’s label or management.

The distinction matters because his strategy was not simply “be independent.” It was to keep different production functions close enough to cooperate: recording, release, physical space and competition. His 2018 album Hip Hop Dream, issued through Kusari Group, joined a memoir title to a new studio album without handing the story to an outside major-label narrative.

That infrastructure did not make him permanently secure. In June 2020, after his first arrest that year, Kan resigned as representative director of Kusari Group and said he intended to begin again as an individual artist. (Music Natalie report, in Japanese) The organization and the artist had to be described separately once again.

The 2020 legal record: two cases, two outcomes

On May 2, 2020, police arrested Kan on suspicion of possessing cannabis in Shinjuku. The Tokyo District Public Prosecutors Office indicted him on May 22 for cannabis possession. A Sponichi report published May 23, in Japanese, also said a urine test had detected a methamphetamine component and that police intended to refer an additional suspected violation of Japan’s stimulant-control law to prosecutors. Kan later acknowledged that positive test in a Cyzo interview, in Japanese.

A planned referral is neither a filed charge nor a conviction. Cyzo later reported that a suspended conviction had been entered and published Kan’s own account of the sentence: 18 months’ imprisonment, suspended for four years. A KAI-YOU Premium follow-up, in Japanese, says it interviewed him after all proceedings had ended. Neither public page itemizes the judgment counts. This profile therefore attributes the sentence to Kan’s reported judgment without labeling it a conviction for the earlier suspected stimulant-law violation.

A second arrest followed on July 6 over cannabis found at a location connected to him in Chiba Prefecture. Chiba prosecutors declined to indict him in that separate matter on August 14 and did not disclose the reason. (Kyodo summary via Livedoor News, in Japanese)

Kan released “Start Over Again” on June 26 and a six-track EP of the same name in December. The title documents how he framed his return to music. It is not evidence that the legal events were resolved by a song, and this profile does not use art as acquittal.

Bladder-cancer surgery and a 2024 battle return

On April 18, 2024, Kan announced a two-month break from work. A Nikkan Sports report, in Japanese, based on posts to his official Instagram account, records that an earlier procedure had identified squamous-cell carcinoma of the bladder and that he had chosen removal of the bladder with an ileal conduit. By April 23, he had posted from the hospital that he was recovering after surgery. The report does not establish every clinical detail, and this profile does not infer a stage, prognosis or treatment beyond what Kan disclosed.

On August 14, he returned to a major tournament at Yoyogi National Gymnasium’s First Gymnasium and faced Hannya in the first round of BATTLE SUMMIT II. Hannya advanced and ultimately won the tournament. The event, pairing and result are documented across the official KING OF KINGS bout video, Hannya’s later first-person interview, in Japanese and ABEMA’s tournament report, in Japanese.

That sequence supplies necessary context for Kan’s later statement that illness and business had displaced his attention from music. It is chronology, not an invitation to turn cancer or a battle result into a recovery fable.

Later medical updates are recorded only to the extent Kan made them public. On February 17, 2025, he reported through Kusari GROUP’s official X account that he had been discharged after five polyps—three more than initially planned—were removed. The report does not establish their pathology or a connection to the bladder cancer. (Nikkan Sports, in Japanese) In April 2026, he posted an image from another hospital stay and said he would be discharged on April 14, but disclosed no diagnosis or symptoms. (Nikkan Sports, in Japanese) This profile does not label either update a recurrence or additional cancer treatment.

Kan Kitchen: the kitchen became a scene-wide room

Kan Kitchen began on YouTube on November 17, 2022, with ralph as the first guest. The premise was modest: cook a dish connected to the guest and talk while making it. (Kan Kitchen launch report, in Japanese)

The guest list made the format more consequential. Artists separated by age, crew, label and public rivalry could occupy the same domestic-looking set. A music video preserves a performance; a battle preserves a result. The kitchen preserved tone, jokes, habits and relationships that discographies cannot show.

By mid-November 2025, Billboard Japan reported more than 300,000 subscribers. Kan also described an unexpected consequence: people increasingly recognized him as “the Kan Kitchen person,” a role that could eclipse the rapper. He said illness and business demands had kept him from concentrating on music and that he wanted to direct that focus back toward it. (Billboard Japan interview, in Japanese)

The final public arc was carefully staged. The program’s end was announced in October 2025. A Billboard Live Yokohama event followed in December. Kan Kitchen Fes: Last Dinner Party took place at Toyosu PIT on March 1, 2026. HIPHOPCs’ post-event record lists GADORO, D.O, Jinmenusagi, SUSHIBOYS, ralph, Benjazzy, MIKADO, Red Eye, G-k.i.d, Charlu, 7 and Worldwide Skippa, with Sonsi added that day; the program ended that month.

HIPHOPCs examines that archive in a separate feature, What Kan Kitchen left behind — Japanese.

From lived material to MOGURA

Kan’s movement into screen work did not end with YouTube. The six-episode ABEMA drama Keishicho Mayaku Torishimari-ka MOGURA—shortened here to MOGURA—began on January 9, 2025. Hannya took his first drama-leading role, and NORIKIYO supplied the theme song “Samidare.” (Oricon production report, in Japanese)

The series follows a police officer with rap ability entering a rapper group undercover. ABEMA said the project drew on a real story Kan had told producer Osamu Suzuki three years earlier; Kan is credited for the original story, not as the screenwriter or sole producer. (ABEMA Times, in Japanese)

ABEMA announced a sequel on May 26, 2026. In that announcement, it reported that the first series had been nominated in the Best Original Drama Series (OTT) category of the 30th Asian Television Awards and had received a silver award at the 2026 WorldMediaFestivals. Those are program honors reported by the producer, not personal acting awards for Kan. The same announcement credits Kan again for the original story and schedules the sequel for winter 2026. As of August 25, the sequel is announced, not completed. (AbemaTV press release, in Japanese)

Five records for understanding Kan

The most recent primary-artist release listed on TuneCore’s Kan artist page is “Yakudoshi,” issued on August 24, 2024 with MU-TON, NIPPS and BAKU. BAKU is credited as composer; MU-TON, Kan and NIPPS as lyricists; and LORD 8ERZ for mixing and mastering. It is a collaborative single rather than a new solo album. It is not described here as his latest guest appearance. (Official track credits)

  1. MS CRU — Teito Hokai (2002) — The North Shinjuku starting point. Hear it as a crew document, not merely a prehistory of Kan’s solo career.
  2. Michi Shirube (2005) — His first solo album and the clearest way into the hard, compressed delivery that made him recognizable beyond MSC.
  3. MURDARATION (2012) — A solo statement released as Kusari/9SARI label activity became public; music and infrastructure arrive together.
  4. “Shinjuku Street Dream” / Hip Hop Dream (2017–2018) — The geography becomes an explicit retrospective frame rather than only the setting of early records.
  5. Start Over Again EP (2020) — A record of resumed production after a year of arrests, indictment, resignation and non-prosecution in a separate case. It should be heard beside that chronology, not as a substitute for it.

Apple Music currently separates parts of the early catalog across Kan, MSC and MS CRU pages. A gap in one artist page is therefore not proof that he stopped recording. Group names, features, physical releases and later digitization all affect what a streaming profile appears to contain. (Apple Music catalog)

BATTLE SUMMIT III: a loss that completes the profile

Kan’s return to a large battle stage followed the end of Kan Kitchen. On May 16, 2026, organizers announced Kan and DABO as a team for the first 2-on-2 edition of BATTLE SUMMIT III.

The pairing carried history because the two had exchanged diss records in the early 2000s. The record supports acknowledging that conflict, but not reconstructing every motive from rumor. At K-Arena Yokohama on August 11, Kan and DABO faced MC TYSON and YOU THUG in round one. MC TYSON and YOU THUG advanced. OZworld and CHICO CARLITO ultimately defeated Zeebra and T-Pablow in the final and won the ¥50 million prize. (HIPHOPCs on-site tournament report — Japanese / AbemaTV official result release, in Japanese)

The result does not strengthen Kan’s résumé. Its value is diagnostic. He had become a tournament founder, label operator and elder figure without protecting himself from the simple public fact of elimination.

In one date, August 11, two versions of his battle career align. He won Sengoku MC BATTLE’s 18th chapter on August 11, 2018. He lost in the first round at BATTLE SUMMIT III on August 11, 2026. The profile requires both.

Kan was also billed for GarinPeiro FES THE ROOTS 2026 at Tazawako Ski Resort on August 14. The organizer’s event page confirms the August 13–14 dates and venue, while J-REXXX’s Artist Pass listing names Kan in the August 14 lineup. By August 25, HIPHOPCs had not located a first-party post-event report or video that independently establishes his set. Status: billed; performance unverified.

How HIPHOPCs evaluates Kan

Kan is sometimes reduced to the hardness of MSC, the visibility of Freestyle Dungeon or the hospitality of Kan Kitchen. None is sufficient alone.

MSC made North Shinjuku a collective voice. UMB turned dissatisfaction with existing battle forms into a national route. 9SARI connected releases, rooms and competition. Kan Kitchen created an archive for relationships that songs could not hold. MOGURA moved lived material into serialized drama.

Those achievements do not erase the 2020 record that can be established publicly or the 2026 first-round defeat. The positive-test report is kept separate from the verified cannabis indictment and from Kan’s account of the sentence because the cited post-proceedings pages do not itemize the judgment counts. Kan’s historical significance is not that every place he built remained under his control, or that every return ended in victory. It is that he repeatedly converted participation into infrastructure.

He did not only represent Shinjuku. He kept changing the number of doors through which Shinjuku—and Japanese rap around it—could be entered.
