If you're dying to visit Tokyo just for the shopping experience, this is as close as it gets. Mitsuwa is a grocery store that only carries Japanese products, from soda and candy to diapers. They also have an impressive assortment of toys by Sanrio and other brands, including a Studio Ghibli section. A visit to the market makes for a complete outing; you can get a matcha or prepared meal and sit at one of Mitsuwa's many tables, let kids ride in those awesome baby-sized shopping carts or try to catch a toy on the claw machines. If your knowledge of Japanese food is limited to ramen and sushi, it'll open your eyes to a new world of flavors — though they have plenty of those, too, if you want to stick to what you know.
