The D3Y Myojo (Venus) was conceived as a wooden version of the Aichi D3A Val dive bomber. This concept was deemed necessary due to the shortage of light alloys that was already facing the Japanese in 1943. The original elliptical wing and rounded tail surfaces of the D3A were replaced with straight tapered surfaces to make construction by semi-skilled workers easier, while the fuselage length was increased to improve stability. Only three production examples were completed before the end of the war. Another planned variant was the D3Y2-K Special Attacker Myojo Kai (Venus Modified), which was to have been a suicide attacker with jettisonable undercarriage, but production had not yet started when the war ended.
