The Kawanishi Baika (梅花, "Ume Blossom") was a pulsejet-powered kamikaze ("divine wind") aircraft under development for the Imperial Japanese Navy towards the end of World War II.

Nazi Germany supplied the Japanese with a great deal of technical data, including details of the Argus As 014 pulse jet engine.

The cargo manifest of the Japanese submarine I-29 lists a single V-1 fuselage as being included in a shipment of equipment.

The only tangible outcome of the Axis cooperation, however, was the construction of prototypes of the Maru Ka10 pulse-jet engine which was to power the Baika.

[1] The currently accepted illustrations of the Baika come from the 1953 published book Koku Gijutsu No Zenbo in which Technical Commander Iwaya (the man who brought the Me 163 and BMW 003 info to Japan) provided drawings of all three versions of the Baika with all versions shown with tricycle landing gear in place.
