Japanese Type D ("Koryu") Midget Submarines. There are at least four different types of midget submarines in this group of about eighty-four boats, though the great majority are of the standard "Koryu" type. The two boats at right in the second row appear to have an enlarged conning tower and shortened hull superstructure. The two boats at left in that row are of the earlier Type A or Type C design, as are a few others further back in the group.

Sort of looks like a sardine cannery, doesn't it?

Does Koryu translate as "Crouching Dragon".  I recall SSI had board game "Operation Olympic", these little buggers, along with frogman and exploding speedboats were slated to play big parts in the Japanese defense of the home islands, in that game.

From The Naval Historical Center Sight:


"In mid-1944, with coastal defense requirements becoming urgent, the Japanese Navy developed an improved version of the Type A, B & C midget submarines. Designated "Type D" and nicknamed "Koryu", the new design was somewhat larger than the earlier types, featured a more powerful diesel engine and had improved operating endurance. The "Koryu" also had a five-man crew, two more than in the Type C, but the same armament of two 45cm (17.7") diameter torpedoes.

The Type D midgets displaced about 60 tons and were 86 feet long. Propelled by a 500 horsepower electric motor, maximum submerged speed was 16 knots. On the surface, with an 150 HP diesel charging the electric batteries, speed was 8 knots and range about 1000 nautical miles. As with the earlier types, individual boats had alpha-numeric names in the "HA" series."
