Reply To: Dining Out with a Wheelchair in Shinjuku Tokyo.
The only one I could find that wasn’t in a hotel or department store (or a Chinese restaurant – since I’m assuming you want Japanese food) was Gyoen Roan (御苑 炉庵)

On one of the restaurant review sites there was a picture of the toilet, and they seem to have a very deliberate ramp, so I assume it is ok… but you might want to ask your hotel to call to confirm.
