Two photos today from the Arawasi collection featuring Tachikawa Ki-54 "Hickory" trainers.
First up is a Ki-54Koh belonging to the "Rikugun Koku Tsushin Gakko" (Army Aviation Communication School). More about the school, here.
The second photo is a very often reproduced one featuring a Ki-54Otsu but here you can find it in better quality.
There is a "Sally" bomber in the background on the right and the other aircraft has tail marking indicating that it belonged to the "Mito Rikugun Hiko Gakko" (IJAAF Aviation School in Mito). So probably this "Hickory" belonged to the same school too.
