(born 1920). Another source states that Seiken Shukumine was tested before Kishimoto accepted him as a student. When Shukumine and Kishimoto met for the first time, Kishimoto took a poker and threw a piece of wooden coal with full force towards Shukumine, who evaded. Kishimoto accepted him as a student on one condition: to promise him to keep the techniques a secret. During the Second World War the 18-year-old Shukumine was drafted into the navy and had to join the Japanese Kamikaze Corps where he became a "kaiten" pilot, a one-man ship packed with explosives used in kamikaze suicide attacks against American warships. Seiken Shukumine was trained to guide this small craft through the protective maze of steel netting that was laid down in the water around the ships, to prevent them from being attacked by these kaiten. He thought in a martial art way to manoeuvre between these steel nettings and tried to think of techniques to avoid enemy torpedoes. He learned that he had to work hard to penetrate the enemy's defenses, and the imagination of the martial artist in him saw how such an approach could be adapted to traditional karate to make for a more supple and dynamic form of combat. Fortunately Shukumine was never appointed for a suicide attack and he survived the war. But when he came back home he found Okinawa demolished by the bombings and his master Soko Kishomoto was killed during the Battle of Okinawa in 1945. Shukumine retreated in solitude for a couple of years and started to develop his karate style with his training as a kaiten pilot in the back of his head. He combined his new techniques with the classic techniques he had learned from his masters Sadoyama and Kishimoto, thus developing the special characteristics of Genseiryū. In 1949 in the town of Itō (Shizuoka Prefecture, Japan), Seiken Shukumine demonstrated publicly his karate techniques for the first time. In October 1950 Seiken Shukumine participated in a karate exhibition arranged by Nippon Television. In this demonstration also participated other masters like Hidetaka Nishiyama (of the Japan Karate Association, JKA), Yasuhiro Konishi (Ryobukai) Ryusho Sakagami (Itosukai), H. Kenjo (Kenshukai), Kanki Izumikawa and Shikan (Seiichi) Akamine (both of Gōjū-ryū). Shukumine demonstrated a.o. the kata Koshokun dai, Tameshiwari (breaking technique, in this case Shukumine broke 34 roof tiles with shutō, the edge of the open hand) and Hachidan-tobi-geri (jumping kick with
