Historical records show that In the early part of 1945, submarine I-361, destroyer Hatsushimo, and newly-built light cruiser Sakawa were all in Kure.
For purposes of the diorama, DD Hatsushimo was renamed from DD Ariake (Tamiya) and CL Sakawa was renamed from CL Agano (Tamiya). Submarine I-361 and Kaitens are from a Hasegawa.
