For years, the Japanese have fetishized small things for their convenience, easiness of storage, and ability to be sold at higher prices even if they're technically not quite as good. Since 1845 when the Everything Smaller Now! Act was passed by Japanese government - consisting of a lone Ninja randomly placing bills, amendments, and even riders onto village doors, holding them in place by stabbing them with a bloody knife then disappearing into the shadows - it has been federal law that all things in Japan must be made at least 10% smaller than anything in the United States.
