A convenient way to get to Odaiba from the mainland. You can also go to Asakusa from Hinode pier. I don't consider it to be a spectacular boat. Sure the view is great, especially at night, but the boat is old. A bonus is that you are able to bring your bicycle on board.
I took this line from Asakusa to Odaiba. It was a really nice and relaxing trip. Unlike some of the trips where they explain all the areas of old Tokyo, these just take you from place to place; with some nice views of the city and the interesting buildings near the shore. For the price, I'd say go for it for some relaxation before you continue on with your bustling Tokyo experience.
Need a little break from the hustle and bustle of the Tokyo streets? Take a ride on one of the Suijo water buses. There are three different locations that you can take a boat to and just relax in the Tokyo harbor. The boat was quite comfortable and relaxing while it took us from Inode to Odaiba. There were a few picture worthy moments along the way as we sat on top of the boat. The boat was not very crowded during the middle of the day and there were plenty of open spaces available on a boat that could accommodate about 100. The ticket was cheap, at 450 yen one way, and when I asked someone, they said that they had all different sorts of boats in their fleet. They spoke very good English and when you bought your ticket from the machine, there was an English version available. Overall, I thought it was relaxing to get away from the crowded streets and onto the water for a brief respite.
Perfectly blending pleasure and function, the water bus ferries allow you to sit back and view the Tokyo skyline while traveling to your next destination, which, if you are riding the ferry, is probably Odaiba or Asakusa. There are quite a few ferries to choose from; each is unique. Some look rather mundane, but one looks part bat-mobile and part submarine, and others are supposed to reflect past eras. You can find times and prices at suijobus.co.jp. The boats don't come that often (about every 2 hours from Hinode Pier) so you'd better plan ahead. Prices range from 460 yen to 1500 yen for adults.
I purchased my ticket at Hinode pier from an automated machine. I think there was an English option, but a very earnest attendant, who spoke English, insisted on helping me and steered me through the Japanese instructions, even handling my cash.
The ferry wasn't very crowded - a few tourists, American and Japanese. You really get to see some of Tokyo's buildings from a unique angle, though. The Asahi building (with the flame sculpture), Fuj building (looks like a space station) and the distant Disney Ferris wheels are some examples. Recommended.
