In this case, Japan has indeed become a country that is very friendly to cryptocurrency, gambling, and various other developments.
In my opinion, Japan is not a country that focuses income only on taxes but other things that should be exemplified by other countries.
Let's not forget the fact that Japan was one of the first countries to legalize cryptocurrency, far ahead of the United States and the European Union. Their capital gains tax rates are also low when compared to most of the other countries. They have a progressive, forward-thinking government and it helps in boosting the economy after such a devastating pandemic.
If other neighboring countries will adapt this ways of thinking that's not impossible we can acquire good results to boost our economy in the future. Taxes regulations would fairly be imposed depending on the income of a specific gambling operation particular with online platforms that caters different branches of potential users.
