The maximum surface speed of the I-370 was up to 13 knots on the surface. The main armament was two 533 mm torpedo launchers, and the secondary armament was a single 140 mm gun and two 25 mm Type 96 anti-aircraft guns. The I-370 was a Type D submarine, which in turn was developed after the Battle of Midway and in connection with the changes in the Pacific War that this battle entailed. They were to operate in waters where the enemy had a clear air advantage and to provide people, supplies and weapons to the Japanese garrisons in the Pacific. Originally, torpedoes of this type were not intended to be armed with torpedoes, but later the assumption was changed. Shortly after entering service, the I-370 was quickly modernized and converted into the carrier of Kaiten-class live torpedoes. In January 1945, the crew underwent training in attacking with a new weapon, and in the second half of February of the same year, the I-370 was directed against the American troops landing on Iwo-Jima.
