Japan surprised me on this list since I thought Gambling is completely ban on this country while only pachinko is the only gambling allowed.
It’s under the criminal code chapter 23 so I’m not sure why Japan is on the top spot with limited gambling games allowed for them to play.
Simple, money!
They have a huge population and a pretty wealthy one, also the pachinko industry is nuts there, it even dwarfs some entire countries GDP.
Also, horse racing, I don't usually bet on Japanese races since the timezone is completely opposite to mine but they have a ton of grade one races and huge volumes on every single bet when a festival is on.
It’s true that’s why I’m surprised about this result. They very limited option yet they are spending huge amount more than most of the country that gambling is complete legal.
Also, Some Japanese is investing on casino to different country since they have Okada Manila here in Philippines that is owned by Japanese billionaire.
They are gambling on casino outside their country.
