Never seen one like it! I recognize the aviation cadet collar tab insignias on flag. The answer will be in the translation
Kinoehi Field Measurement Association
[Sorry for not wanting to polish the computer-generated translation!!!]海軍飛行予科練習生
1944年（昭和19年）12月に第1期教育開始。海軍特別志願兵の朝鮮人日本兵・台湾人日本兵対象。実例 は1期（朝鮮出身者50人・台湾出身者50人）のみで、鹿児島空で教育開始後、1945年6月に土浦空へ異 動して教育中に終戦。
甲種飛行予科練習生制度の導入以降、両制度を甲・乙と言う優劣を表す名前に変更した為、また昇進速度の違い などもあり、練習生間での対立が問題となった。予科練航空隊を増設する際、甲飛・乙飛を分離する計画もあっ たが、戦況の悪化によって後発航空隊による甲乙分離計画は立ち消えとなり、末期まで尾を引いた 。

Conflict Between Kinoehi and Otsuhi
Class A flight preparatory course since the introduction of the trainee system, because it was changed to the name that represents the relative merits to say both institutional and A - B, There are also differences in promotion rates, conflict between the Trainee has become a problem. When installing additional Yokaren Air Corps, there were also plans to separate the Kinoehi-B flying, party hereto separation plan by the late Air Corps by the deterioration of the war situation becomes extinction, minus the tail until the end.
Japanese Wiki source
So .... perhaps this is the flag of an association of Electrical students of the Navy Flight School?
(As always, I reserve the right to be wrong!)
Densoku ..... I should have just looked up that portion! It translates to Operations Specialist rating. The Japanese wiki page for densoku directed me to a US wiki page about the US Navy Operations Specialist rating
So ..... your flag is still an association flag, but for radar technicians who graduated the A-Course at the flight school.Brief history
The rating started from the radarman (RD) rating. When the radarman rating was split up into OS, electronics technician (ET), and electronic warfare technician (EW) ratings, the original RD rating badge continued to be used by the operations specialist. It symbolizes the radar scope (circle portion of symbol) oscilloscope radar (A-scope) used to determine a targets range from the radar antenna (the two spikes in the line drawn across the scope), and the arrow represents the ability to detect the azimuth or direction of the target.
(*STILL* reserving the right to be wrong .... and fully capitalizing on that right.)
Very interesting. Didn't see that one coming...
Great work Guy!!! Above and beyond.
My greatest fear is that one day I will die and my wife will sell my guns for what I told her I paid for them
"Don't tell me these are investments if you never intend to sell anything" (Quote: Wife)
Very nice flag......... !
Just for clarification, 甲飛 kinoehi is a four-syllable compound-word.
甲 - きのえ kinoe [key-no-ay]
飛 - ひ hi [hee]
