Three wheeled motorbikes
In Japan three wheels motorbikes are pretty popular. There are also many “big” bikes, but you can’t see many little “scooters”. I’m used to Europe where “scooters” rule the big cities. I suppose the main reason is users who would have a “scooter” in Europe they have a bicycle in Japan. There are many many bicycles here.
