We had a great time with Taku-san. In the morning he was our tourist tour guide, showing us the spectacles of the city. But the main attraction was the Sumo Tournament!!! He arranged Sumo tickets for us (which I was unable to get) and gave us all the Sumo need to know information and more. He is a real enthusiast but firm enough to keep us on track and get to places in time to keep our schedule. We experienced so much in a day.
