No tourism website would be complete without options for vegans and vegetarians, and Suginami (especially Nishi-Ogikubo) has its growing share of both in Tokyo. Japan is especially hard for vegetarians and vegans because basically everything is cooked with fish stock-- even vegetables, so be sure to always check if you are strict. If they don't speak English and you can't confirm, you should always assume it is NOT vegetarian if it is cooked. Here are some options that are sure to be vegetarian or vegan as stated, or otherwise places that have vegetarian options available.
