During development of the AA gun tank, the Imperial Japanese Army experimented with various configurations.

It was equipped with a single converted Type 98 20 mm AA machine cannon.

During trials, it was determined that the chassis used for the Ta-Se was too small to be a stable "firing platform".

The gun tank was equipped with a modified twin Type 2 20 mm AA machine cannon mounted on a raised platform with a gun shield.

The original Type 97 Te-Ke tankette turret was removed, and a single Type 98 20 mm AA machine cannon was mounted on the modified chassis without a protective gun shield.
