There are three 105-mm howitzers and four 105-mm guns in use by the Japanese Army. These guns are designated 10-cm by the Japanese but have an actual bore diameter of 105 mm.

The projectiles are in most cases interchangable for use in all these weapons and are as-sembled with different size cases for use in the different weapons. Only one weapon, the type 14-year A.A. gun used fixed ammunition, all the other weapons using semifixed am-munition.

In this section the cases and projectiles will be treated separately as was done with 75-mm ammunition.
