Entrepreneurship in Asia (Japan / Korea)

Hello !

I have built a platform for interactive training (science, code, AI) and these days I dream about Asia é_è

I have the vague feeling that Japan could be an interesting country for online / tech business as :

• Aging population lead to more favorable visa programs (startup visa, skilled worker visa, etc.)
• Entrepreneurship culture is not much developed, so less competitors

are there people here with experience in countries like Japan (or Korea) ?

• Is it hard to setup and live there ?
• Is it hard to sell B2B ?
• Same question B2C ?

Any insight appreciated
