What Wikipedia says

The Kayaba Ka-1 and Ka-2 were a series of autogyros produced by the Japanese manufacturer Kayaba Industry. Their official Army designation was the "Ka-Gō observation aircraft" (カ号観測機, Ka-gō-kansokuki) (Gō being translatable as "number"). It was the first series of armed autogyros to be used operationally.
