I thought some of the strange looking Pachinko Parlors you zoom by were more interesting than the rice paddies, but I suppose that's because of my weird sense of humor.
My weird sense of humor always led me to look for the 'hole in the wall' when walking by a Pachinko Parlor.
Cash payoffs are illegal, so one must exchange the steel balls/winnings for special tokens before leaving the Parlor. Outside, there will be a slot in a nearby wall or shed. Place the tokens in, and someone will pass back cash.
It's illegal, but arrests are very rare.
