The Type 98 20 mm AAG Tank or Ho-Ki was a Japanese self-propelled anti-aircraft gun using the Type 98 20 mm gun combined with the chassis of the Type 1 Ho-Ki armoured personnel carrier. The gun crew worked from a raised platform with a modest amount of protection from the sides - the twin 20 mm guns fired through a large gun shield gave further protection for the crew from that direction.

During development of the Ho-Ki the Japanese Army experimented with various configurations. A single gun variant was the Ta-Se, from "Taikuu Sensha" ("anti-air tank").

The Ta-Se was developed based on the failures of the Ki-To; the Ta-Se had additional protection for the crew. Trial production of Ta-Se was completed in November 1941, but adoption into service was cancelled because the hit ratio of the Ta-Se's single gun was inferior. Development of the twin gun Ho-Ki began in 1941, and was cancelled in 1943. Completion was planned for March 1944.
