Tsuguo Sakumoto, 7 times consecutive world champion, and coach to 9 world champions including Arata Kinjo, Takuya Uemura and Ryo Kiyuna. He is 9th-dan in Ryuei-ryu karate. Ryo Kiyuna is one of Japan’s best chances to win a gold medal at the Tokyo 2020 (2021) Olympics so Sakumoto Sensei is more than ever a very busy man. Luckily he liked the portraits of him I shot in 2014 so we managed to get to interview him last September for the Sensei: Masters of Okinawan Karate Series. You can learn more about the series, and even how to support is here: https://travel67.com/the-karate-masters-portrait-project/sensei-documentary/
After photographing Seiei Nakaza sensei, I took a few shots of his senior student, Brian Hobson. It might seem strange to call a 7th dan black belt a student, but even those who have studied karate for decades often visit Okinawa to learn from the masters of the art.
