The primary kind of bayonet used on Japanese rifles in World War II was the Type 30, introduced in 1897. During World War 2 these would be used on the Type 38, Type 44, and Type 99 rifles, and even the Type 92 Machine Gun. This is a fantastic example of a Early-War period bayonet with curved quillon and rounded pommel, the makers marking indicates it was produced by the unknown company under the supervision of Kokura. The blade has been lightly sharpened as all combat worn examples would have been. The blade overall is very nice and is a bright non blued variation as most early examples would have been. The original canvas tropical frog is also still attached and has a semi damaged tongue. Overall this is a fantastic example of a Japanese combat bayonet set.
