If Japan cancelled the Yamatos, where could the resources go?

What might Japan gain if Mitsumasa Yonai had stopped the Yamato-class programme?

Japan could redirect capacity into lighter carriers, fast battleships, and unfinished hulls, creating more operational options rather than a guaranteed decisive advantage.

Cancelling the Yamato programme would create resource depth rather than an automatic strategic revolution. The released industrial capacity might finish hulls otherwise left incomplete, build battleships displacing 45,000 to 50,000 tons, or add one to three carriers to the Kido Butai. At Pearl Harbor, extra carriers could enlarge the air strikes or keep complete air groups ready for anti-ship work in case the American carriers appeared. Fast battleships might also make a bombardment attempt possible. These are additional operational choices, not a guaranteed shift in the balance of power.
