Tokyo bay cruise
...with lunch or dinner - wonderful time to see what surrounds Tokyo bay
If you are Tokyo tour proficient, you must know the name "Hato Bus". Well, Hato Bus is not only a tour bus company but also owns cruise company. You can enjoy nice lunch or dinner on the Tokyo bay cruise together with buy tour to other places.
I went with family for Christmas lunch and it was fantastic experience. On the tour course we chose, we gathered at Hinode Pier and got on the fairly big cruiser called "Symphony". We had nice view from inside as well as on deck, nice lunch, and nice mini concert inside.
There is English tour as well using this cruise. Google up Hatobus and see if there is any that get you interested.
Hope this helps.
