[1] He retired early from the sport and became the track and field coach for the Japanese Association of Athletics Federations (JAAF), leading teams to the Olympics from 1964 to 1992.

Born in Jōge, Hiroshima, Kogake began to compete in the triple jump while at high school – the track and field event had gained much popularity in Japan through Olympic gold medallists Mikio Oda, Chūhei Nambu, and Naoto Tajima.

[3] At the 1956 Japanese Championships, which served as the Olympic Trials, he jumped what was then considered a world record distance of 16.48 m, adding some 20 cm onto the previous mark (Adhemar da Silva had jumped 16.56 m in March 1955, but this had been achieved in Mexico City and had been aided by the high altitude).

[3] Kogake's success came with a penalty in the form of an ankle injury which impeded his performance at the 1956 Melbourne Olympics.

He was honoured at the Imperial Palace in 2005 by being awarded a third class Order of the Rising Sun (Gold Rays with Neck Ribbon).
