Part of the 5,500 ton group of light cruisers in the Japanese Navy; 5 ships from port to starboard (top to bottom): Kiso[1942], torpedo cruisers Kitakami and Oi (same sculpt; 1941), Tama[1941] and Kuma[1941]. Tama has the extended platform to the starboard of the catapult, while Kuma's at port side (Kiso doesn't have this as she's not equipped with a catapult).
