All 47 Japanese Prefectures Have Produced a Sanyaku Sumo Wrestler

On October 28, 2026, I published Churanoumi Becomes First Sumo Wrestler From Okinawa to Reach Sanyaku. I cited to a news report in Mainichi as my source. While I discussed now-Komusubi Churanoumi and his “career year” to date, I missed noting an additional fact about his historic sanyaku promotion for the upcoming Kyushu Grand Sumo Tournament. Okinawa had been the only one of Japan’s 47 prefectures with no sanyaku sumo wrestler. As a matter of logic, Churanoumi’s ranking means that all 47 prefectures in Japan have produced at least one sanyaku wrestler.
