Kasumigaura Kokutai

(-  )

 Katakana-letter (Ka-  )

 Kasumigaura was evtl a private flying school which contracted to the Japanese Navy and essentially owned obsolete types such as early A6M2s and A5Ms. Perhaps Kasumigaura did something completely different (light blue, for all we might know) to suit their needs.
As I say, Some  think that Kasumigaura was a private school which trained pilots before the war, and was pressed into action to help train pilots during the war. If true, perhaps their payment, partially, was to receive obsolete planes.
Minoru Akimoto described Kasumigaura Kokutai:
"On November 1, 1922, an air group was organized by abolishing the Rinji Kaigun Koku-jutsu Koshubu [Temporary Naval Aeronautics Institute]...."
1922, November 1   -  Formed in Kasumigaura
