Online gambling is banned or illegal in so many countries. Still, online casinos are operating in most of those countries without having any difficulties. Most of the casinos accept players from Japan, and I haven't seen any popular crypto casino to create a different platform for the residents of Japan. Anyway, I just noticed that my country is listed as  prohibited country in Betpanda. They never give any warning when I visit Betpanda. Anyway, I won't play at Betpanda anymore for this reason.
