Hokoku number 64 was a Navy Type 90 Carrier Fighter or Nakajima A2N1-3 donated on June 17, 1934 by students of universities and colleges of technology from all over Japan.
Note the repetition of the hokoku inscription on the upper wing.
No less than 39 Nakajima A2N were donated as hokoku, the first was #5 and the last was #84.
Hokoku aficionado Ed DeKiep sent us another photos of Hokoku#64.
Thank you Ed and sorry for the delay to post the image.
