From Shizuoka to the World; How Prof. Shoya built a career in BJJ before a market existed in Japan

Professor Shoya Ishiguro is Japan's top black belt competitors and a fixture at the highest levels of IBJJF competition. He joins the podcast in Los Angeles, where he has been training for three weeks ahead of the IBJJF World Championship, preparing for rematches with rivals Diego "Pato" Oliveira and Rerisson alongside coach Isaac Doederlein. The conversation covers ground that goes well beyond competition. Shoya started jiu-jitsu at 12 in Shizuoka, at a time when most people in Japan had never heard of the sport. His father brought him to the gym hoping he would become an MMA fighter, a generation raised on Pride and Sakuraba. Shoya chose jiu-jitsu instead, and stayed with it for seventeen years through a period when there was no real market for full-time athletes in Japan. He trained, taught, and waited for the sport to grow into something that could sustain a career. It did. The episode gets into what high-level preparation looks like without a dedicated personal coach, how Shoya studies his own mistakes during and after sparring, why he added strength and conditioning only recently and what changed when he did, and what his mindset is in the seconds before a match begins. He talks about the cultural thread that runs between Japanese martial arts and Brazilian jiu-jitsu, a connection he says Brazilian practitioners often feel more clearly than Japanese ones do today. There is also a conversation about fatherhood, about the difference between how classes run in Tokyo versus Shizuoka versus Los Angeles, about why he tells every student to compete, and about what he actually wants to show Pato the next time they meet on the mat. Shoya teaches at Arta BJJ in Minato-ku, Tokyo, near Tokyo Tower.
