I have a 1:1200 scale model of the YASUKAWA MARU made for use on the Navy's submarine attack teacher during WWII. It's metal with brass cowl vents & wire masts. It's a little beat up, but accurate & nice to have. These models were described in Ship Models for the Military by Fred Dorris, pages 26-29.
Attached are pics of the Spider Navy's SN-2-14 Yasukawa Maru.
with the Wirral WM110a Civilian version

Yasukawa Maru (Kawasaki Kisen: 6770 total tons)
It was purchased and repaired from the English ship "Silver Cypress" that was severely damaged by a fire accident. In 1941, the army was requisitioned the ship and it was active as an air defense ship during the Pacific War. On November 2, 42, after being attacked by US military aircraft in the Strait of Dumper, it became non-navigable and was disposed of by the bombardment of a marine vessel "ÍJ".
