A lineage map, not a directory

The reference gym for defensive technique in modern kickboxing. Giorgio Petrosyan spent close to a decade at the top of the sport barely being hit, which under round-by-round ten-point-must scoring is very close to optimal. The gym now trains fighters who beat that style as well as fighters who use it — Chingiz Allazov’s knockout of Superbon came out of the same room.

Kurosaki Kenji was a Kyokushin karateka central to the first generation of Japanese kickboxing, and his gym is the upstream source of the Dutch school. The Amsterdam Mejiro Gym is named after it. Trace the lineage of almost any European kickboxing gym backwards far enough and it arrives here, which is a strange result for a style everyone now calls Dutch.

Kazuyoshi Ishii’s Kyokushin offshoot, and the organisation that founded K-1 in 1993. That is the single most consequential fact about it: the rulebook nearly all modern kickboxing uses — punches, kicks, knees, no elbows, immediate clinch break — was written here to answer a karate promoter’s question about which striking art produced the best fighter.

Mas Oyama’s knockdown karate is not kickboxing, but it fed the sport a specific kind of fighter: extreme body conditioning, head kicks as the primary knockout weapon, and — because the code bans punches to the head — very little head movement. Andy Hug’s axe kick makes sense only against opponents whose guard is set for round kicks, which is a Kyokushin habit carried into a code that punishes it.

Masato was the face of K-1 MAX in Japan and the domestic counterweight to the Dutch and Thai contingents — high-volume hand work, forward pressure and a willingness to be in every exchange. His gym continues the Japanese lighter-weight tradition that RISE, Krush and the revived K-1 now run on.

Takeru is the defining figure of the revived Japanese K-1, and the gym around him represents what the domestic scene became after the original organisation collapsed: smaller, entirely Japan-facing, and technically excellent at the lighter weights that were always the best part of K-1 anyway.

The room the Dutch style came out of. Jan Plas trained in Japan under Kurosaki Kenji, named his Amsterdam gym after Kurosaki’s, and brought back not a technique list but a method — long high-volume pad rounds in which the coach never lets the fighter reset between elements of a combination. Rob Kaman’s wins in Thailand through the 1980s were the evidence that the method travelled, which is why the Dutch arrived at K-1 in 1993 already expecting to win.

Thom Harinck built Chakuriki in parallel with Plas’s Mejiro, and between them the two gyms defined Dutch kickboxing before anyone outside the Netherlands was paying attention. Chakuriki’s reputation was for producing heavy, aggressive fighters, and Branko Cikatić winning the first K-1 Grand Prix in 1993 announced the Dutch scene to a global audience in the most direct way available.

Golden Glory ran on scale: a large stable, a management arm that negotiated for the whole roster, and a pipeline that took big athletes from other sports and turned them into heavyweight kickboxers. At its peak it supplied a substantial share of the K-1 heavyweight field. That concentration was also a fragility — when Golden Glory and K-1’s management fell out in 2011, a large part of the division became unavailable at once.

Mike Passenier’s gym became the destination for fighters who wanted the most aggressive end of the Dutch style — pressure, power and a willingness to trade that produced some of the most watchable heavyweights of the GLORY era. Badr Hari is the defining product: technically excellent, genuinely dangerous, and stylistically the opposite of the conditioning-first approach that beat him.

Cor Hemmers coached at the top of the sport for decades and later ran matchmaking for GLORY, which gives his gym an unusual position: it produced fighters and then shaped the promotion they fought in. Ernesto Hoost, four-time K-1 Grand Prix champion, is the technical high-water mark of the Dutch method — combination work at a level nobody in the heavyweight division has matched since.

One of the Amsterdam rooms that kept the Dutch pipeline running through the K-1 years. Andy Souwer’s K-1 MAX success is the clearest illustration of what the method does at lighter weights: the same combination chains and the same refusal to reset, applied by a fighter fast enough to run them at MAX pace against Buakaw and Masato.

Buakaw’s own camp, built after he left Por. Pramuk. Its interest for kickboxing rather than Muay Thai is the adaptation it represents: a Lumpinee stadium champion who won K-1 MAX twice by discarding the clinch game and rebuilding his output around hand volume and the left kick. That adjustment is the clearest demonstration available of what the clinch break rule actually costs.

The camp that developed Buakaw before his K-1 years, and a useful reminder of how the Thai pipeline actually works: fighters are raised in a stadium system that scores balance, control and the later rounds, then exported into promotions that score none of those things. Everything Buakaw had to unlearn for MAX, he learned here — and the left kick he kept was learned here too.

One of the Thai camps that adapted successfully to the modern promotional landscape, running Muay Thai, kickboxing and mixed martial arts programmes side by side. Stamp Fairtex competing across all three codes under ONE is the clearest example of what that produces — and a rare chance to watch the same athlete with and without elbows and the full clinch.

Superbon’s knockout of Giorgio Petrosyan is the fight that marks the boundary between two scoring philosophies. Petrosyan’s decade of dominance was built on volume-and-defence scoring; ONE instructs its judges to weight fight-ending damage above accumulated clean landing, and under that criterion one head kick outweighed everything else on the card. The camp is worth knowing for that fight alone.

A traditional Bangkok camp that opened to foreign fighters and became one of the standard destinations for Europeans wanting Thai training. Its relevance here is what visitors report learning: not new techniques but a different relationship to volume and pace, and a clinch game that most of them will never be allowed to use under the rules they compete under at home.

Duke Roufus came out of the American full-contact scene — the same family and the same era as Rick Roufus, whose 1988 loss to Changpuek Kiatsongrit taught American kickboxing what the low kick was worth. The gym that grew out of that lineage now teaches leg kicks as a foundation and exports strikers into mixed martial arts, which is about as complete a correction as a scene can make.
