War era bayonet

Nagoya Arsenal

            Sugawa (p. 109) states that Nagoya Arsenal engaged in bayonet production itself in 1936-37, and then supervised subcontractors. The Nagoya mark, shown below, is supposed to represent the twoshachi, or mythical dolphins, that adorn the ends of the roof of Nagoya’s castle, the city’s chief landmark, and are supposed to be its protectors. If you use your imagination, the two horn-like parts between the outer circle and the two inner circles could be thought of as the bodies of fish-like creatures with their tails in the air, and the small circle at the bottom representing their heads. Sugawa puts Nagoya Arsenal production at about 87,000 units

Riken Kozai

            Another relatively recently identified maker, Riken Kozai’s mark is frequently called “Nagoya diamond”. The company’s headquarters was in Gunma prefecture, but the factory was in Tokyo. Production is estimated by Sugawa at around 250,000 units, the lowest of any of the subcontractors.
