Many visitors to Japan from the West are cautious of Japanese sweets with the idea that beans shouldn't be sweet (like the red azuki bean, used in most Japanese sweets), but you shouldn't knock it before you try it! Even still, there are matcha and mochi varieties of sweets as well, so surely something for everyone! In Suginami, Tokyo, Asagaya's Pearl Center is well-known for Japanese sweets and a good place to start.
