This is an excellent rare example of the Japanese Type 100 HE Mortar Round used with the Type 97 (1937) and later the Type 99 small trench mortar. This is based on the Stokes-Brandt design as was the U.S. 81mm, and this round was actually interchangeable with the U.S. M43A1 shell.

The Japanese Type 100 round had a maximum range of about 3,000 yards. Loaded weight: ~3kg (6.9lbs) of which 1 pound was TNT.

The stenciled text translates-

Kyoku Ho is the abbreviation of "Kyokusha Hoheiho", which the IJA called the infantry mortar.

Also included is the type 100 impact fuse which is typically missing on inert examples such as this.
