Japan must be really desperate for new tourists and new investors,in order to provide such liberal gambling legislation and infrastructure.I guess that their economic growth isn't enough so they are moving towards lucrative industries such as gambling.
A developed country like Japan really needs to think for adoption like this. We know that the industry of gambling continues to soar high so its a good chance now for Japan to be a new gambling hub in Asia and I believe this will be supported by many Gamblers in Japan.
Japan has always been pioneer in accepting technologies. They are the ones who were first to accept crypto and make it legalize. Many tourists will be attracted to Japan and they must be aiming to become the gaming hub of the region.
