As a religious vegetarian with gluten intolerance, I felt very left-out about the stretch of Tokyo Station dedicated to ramen, that special noodle dish written in foreign characters (but which we think of as exclusively Japanese). However, vegans recommended a place that wasn't on the Tokyo Station Navi app called Soranoiro Nippon, and I eventually found it! It has gluten-free brown rice noodles, which can be added to their vegan tan-tan noodle soup. The soup itself isn't entirely gluten-free, but my condition allows for some minor, incidental gluten, so I went for it. It was superb - I have no regrets!
