The T-1s were transports based on the Matsu class and designed to carry landing craft and amphibious tanks. One set of machinery was removed to make room for the troops and cargo, which limited their speed. They were quite versatile as shown by the variety of possible cargo loadouts. Landing craft were launched off of stern rollers.

Unfortunately for the Japanese, they were completed at a time when the Allies were doing all the invading. However, the ships were pressed into service to reinforce the Leyte garrison.
