Ferry ride, Tokyo?
 

Hello, what are the tips for a ferry ride in Tokyo? Is there a time of day that is recommended? (Sunset? Avoid rush hour?)

Do you mean the boat along the Sumida River?

I found it stultifyingly boring. If photography is a goal, times within an hour or so of sunset are always best. Beyond that, I can't say ... but maybe you mean something different?

There are plenty of ferries in Tokyo, so you'll need to tell us which one. If you are just looking for a water based tour, here are a few:

Hmm maybe the yakatabune will suit. I was thinking one without food, at sunset, or 90 minutes or so...thank you.
