This Japanese Arisaka bayonet was manufactured at the Jinsen Rikugun Zoheisho Arsenal in occupied Korea. It features a straight, single-edged blade with squared pommel and simplified construction typical of late-war production. The wooden grips are riveted directly to the tang, and the ricasso is stamped with the Jinsen Arsenal mark.

In Johnson’s system, this piece is identified as Variation P, while in Labar’s reference it corresponds to Variation R (LB-162). The rarity rating is Rare 4, making it a significantly less common example among surviving Arisaka bayonets.

The bayonet is fitted with an LBS-21 scabbard, itself an uncommon type. The frog cannot be conclusively identified without viewing the reverse side, but the overall configuration is consistent with wartime Japanese issue equipment.

This is a scarce and desirable Jinsen-manufactured bayonet, representing one of the late-war variants produced outside mainland Japan.
