The Hotaluna is a futuristic sightseeing boat that runs from Asakusa to Odaiba. The boat is one of two, the other being the Himiko, which was designed by the legendary manga and anime artist, Leiji Matsumoto. I am not a fan of manga or anime, so I had to look him up, but he has been involved in a lot of significant stories. If you are interested, I’ll link his wiki page here.
If you want to cruise the Sumida River in one of these boats from the future, go to Asakusa and you will find the ticket office right next to the Azumabashi Bridge. A one-way ticket to Odaiba will cost you ¥1720. The link for ticket and route information is here.
