Training of new IJNAF cadets especially those of the "Shonen Kokuhei" programme included modeling, to familiarise the teenagers with the basics of aviation. Those days it was wood and everything was completely scratch built.
Arawasi will be in the Shizuoka show this Saturday. Expect a lengthy and detailed report on everything regarding Japanese historical Aviation. New releases, the booths of the model makers and many many photos of Japanese aircraft models.
