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.
Is am surprised that Nigeria is not among but I know Nigerians are really gambling.
It doesn't matter how many gamble, what matters is how much they gamble.
And with the US gaming industry being nearly $250 billion, that's close to the entire GDP of Nigeria, basically everyone there would need to gamble it's entire wage to come close to those numbers. Nigeria barely has 3 billion in the gambling industry, it's peanuts compared to the big guys.
