The first J1N1-S is the only one on the sheet in dark green over gray (the rest all being overall dark green). Coded U1-13 in white on the tail, this plane also has white-edged hinomarus for the fuselage upper wing. Flown by CPO Shigetoshi Kudo and Lt. Akira Sugawara of Kokutai 251 out of Rabaul-Lakunai, July 1943, this plane had a total of nine kills and one probable. The second J1N1-S was flown by CPO Tetsuya Hatao and CPO Nanpachi Yamada of Kokutai 202 out of Manggar Air Base in Borneo, January 1944. This team was the most successful night-fighter team over Indonesia, with several kills to their name including a pair of B-24s shot down on the night of January 13, 1944. These two kills are silhouetted in white on the tail underneath the red code '02-03'.
Moving to the two J1N1-Sa planes, the first choice is coded YoD-187 and was flown by Lt. Sachio Endo Osamu Nishio of Kokutai 302. Flying out of Atsugi Air Base in 1945, this plane shot down a total of five B-29s and had a probable count of nine. The kill markings are depicted as flower blossoms on the fuselage side.

Flown by CPO Ykzu Kuramoto and Shiro Kurotori, this team had a total of six confirmed kills and two probables, all B-29s. This plane is the only one of the four on the sheet equipped with the FD-2 radar.
