Japan is one of the world’s leaders in manufacturing electronic appliances. Japanese brands are constantly innovating and employing new technologies to make dishwashers smaller and faster. Also, they are more efficient and affordable. Japanese brands were the first ones to come out with smaller tabletop dishwashers as an alternative to built-in full-size dishwashers.
