I love wandering around Ryogoku. Some great craft beer bars, some great restaurants selling sumo style food, a lovely garden with no entry fee, and obviously, for a chance to get a glimpse of a sumo wrestler riding a bicycle. Just hanging around in the area of Ryogoku Station, or around one of the shops that sells sumo sized clothing, you are bound to see a sumo wrestler or two, as they freely wander around this area of Tokyo.
