For Hotaluna’s roof deck, start at Hinode

In Tokyo, starting at Asakusa adds about 45 minutes and ¥1,000 to the Hotaluna ride to Odaiba. It adds the Sumida River and its bridges; the roof deck opens only between Hinode Pier and Odaiba, a leg of about 20 minutes. Rain closes the deck. The full Asakusa–Odaiba Seaside Park trip is ¥2,000, about 65 minutes via Hinode. Boarding Hotaluna at Hinode is ¥1,000 for about 20 minutes. Those are adult one-way fares. Direction matters as well: on Hotaluna’s Odaiba-to-Asakusa sailing, the roof deck stays closed. For the short outward ride, Hinode Pier is two minutes on foot from Yurikamome’s Hinode Station, or about eight from Hamamatsucho.
