Remarks by Johan Visschedijk: "The H8K2-L Seiku (Clear Sky) was a transport variant with accommodation provided for 29 to 64 passengers and had been developed from the original H8K1 prototype. The transport variant was fitted with a 0.787 in (20 mm) and a 0.51 (13 mm) gun as defensive armament. A total of 36 H8K2-L transports was produced between 1943 and 1945."
