I don’t know if you’d care to read what I wrote about the so called land reforms in another thread, but the TLDR; version is:
Farmers actually were doing pretty well under Japanese rule before the war went poorly for the Japanese. Many Taiwanese farmers did even better than farmers in Japan, as the demands for both Taiwanese sugar and rice created a balance that kept the prices up. The lost of the Japanese market post war was a bigger hit to Taiwanese farmers than the rent itself.
I remember once writing a post commenting on how the Japanese already did similar reforms, but I guess that post was made in some temped thread and is now gone forever.
