The Type 5 Na-To (五式砲戦車, Go-shiki hōsensha), officially known as the Experimental 7.5cm self-propelled anti-tank gun Na-To (試製七糎半対戦車自走砲 ナト, Shisei nana-senchimētoru hantaisensha jisōhō Na-To) was the penultimate self-propelled anti-tank gun developed by the Imperial Japanese Army in 1945,[1] during the closing stages of World War II.

Towards the end of the Pacific War, Japanese field commanders realized that nothing in the inventory of the Japanese Army would be able to withstand the increasingly advanced tanks and armored vehicles fielded by the Allies, and that a more powerful version of the Type 3 Ho-Ni III was necessary.

[1] The superstructure had an open top and rear, with an enclosed armored drivers cab.

For the Type 5 Na-To there was added a "shielded platform" for its main gun.

[1][2][5] The Type 5 Na-To tank destroyer was intended to become part of the defenses of the Japanese home islands against the projected Allied Invasion.
