I mean as a symbolic title as the head of some sort of co prosperity sphereMandate of Heaven doesn't exist post 1911 and Japan's plan for China was puppet states not the Japanese emperor as emperor of China.
This is within the 1900s not 1700s or before. Chinese can’t just swarm in like they did in Manchuria and become majority because Japan is a island and the Japanese would probably heavily regulated movement of non Japanese to the home islands. The emperor is also going to stay in Japan. Japanese also have a much more strict view of race and ethnicity that is more similar to the west then China. If they conquer China I could see Japan and some of there holding like Korea and Taiwan becoming just as nice in industry, wealth, living standards, and technology as otl. They would be first world regions. This could also apply to some coastal areas and cities in China under their direct control. The rest of China would probably be divided up into puppet nations that are full of sweatshop factories and raw resource laborers who often use cheap labor and even child labor. Conditions similar to otl Chinese factories, mines, and farming. These industries are probably controlled by Japanese interest groups or people who often use the local government as a tool for their own gains. Japan uses these countries like banana republics or places to produce cheap products in large numbers for very low cost while Japanese lands produce more high end and high tech products within its actual country. Japan would profit greatly off Chinese labor and resources.He'd eventually move to China and Japan would become a backwater province.
The Empire of Chipan, nice name.Is it possible and is it a smart decision?

Well, for starters, Imperial Japan historically ruled their occupied areas of China (outside of Manchukuo) through a series of puppet Chinese republics, so no.Is it possible and is it a smart decision?
