Tanaka Shori was born in Tsukushino city, Fukuoka prefecture. Near the end of the War ended he was elementary student sixth grade and he saw many tokotai planes taking off from nearby airfields. He was an eyewitness to 4th Sentai’s unit leader of the “Kaiten-tai” 2nd Lt Yamamoto when he rammed his Ki-45 "Toryu" on a B-29. He will never forget Yamamoto’s name written in hiragana on the crashed tail remains of the plane.
Building models of aircraft he saw as a child always bring back bitter memories.
After the War his father worked in a nearby US base which he visited very often and listened to jazz songs on the jukebox. Growing up he became a quite famous jazz singer and had the chance to meet and talk to many famous veteran pilots. His other hobby is photography and Tanaka-san has an incredible collection of vintage cameras.
He has released a small book with photos of his models and information about each aircraft.
