Osaka is the perfect place to go if you want a variety of different Japanese food. For a good deal, go for lunch. There is even a teriyaki stir fry where you can choose your own ingredients and have it made the way you like it. For dinner, there is sashimi along with a hot pot. Just make sure you don't stuff yourself too much and have room for dessert. There's an array of cakes, Japanese pudding, fruit and green tea/red bean ice cream.
