Tokyo food recommendations (healthy)

Hello,

So im travelling in Tokyo with a friend, first 3 days. They seem to just hate Japan local food such as Yakiniku, Tonkatsu, Omurice. The only thing she was able to eat was Sushi and like seafood (we went to a Izakaya and ordered seafood like eel which she liked). She has like bad acne, and just said fatty meat, deep fried she just can't seem to eat without feeling sick. In the Izakaya place we had we had some beef which didn't taste too fatty but was still nice and soft.

Can anyone recommend like healthier Japanese food (specific places would be helpful) for us to go to in Tokyo. Sushi recommending are also welcomed if it's not too expensive.
