Photo: 円周率３パーセント (Enshuritsu 3 percent) / CC BY-SA 4.0Toba Aquarium is the bay's all-weather option: it is open every day of the year, it is a 15-minute walk from the tender landing, and it is indoors. On a wet or windy day, when the tenders may be disrupted anyway, it is the sensible fallback to the island and the bay boat.
The headline animal is Serena, a dugong. The aquarium says she came in on 15 April 1987 and describes her as the only dugong kept in Japan; at arrival she was 147.5 cm and 67 kg, and the 2026 article gives 263 cm and 375 kg. The aquarium's own site also puts its sea otters up front, with a live camera on the sea-otter tank and a book for their 40th anniversary.
The catch is the price and the pace. At ¥2,800 it costs more than Mikimoto Pearl Island, there is no senior discount, and it is a big building that takes a couple of hours. If you only have one stop, take the island and its ama divers instead; if you have a spare hour and a wet day, take the aquarium.
Five things the plaques won't tell you
- Last entry is 16:00 on ordinary days (16:30 in Golden Week, August and Silver Week), and closing is 17:00, so do not leave it for the last hour on a late call.
- Buy the online combination ticket with Mikimoto Pearl Island (¥4,000 adult, valid one month), since the aquarium's desk price is ¥2,800.
- It is open all year with no closed days, which makes it the safe choice when other sights are shut.
- The aquarium's site mentions a sea-otter live camera, so you can check what the animals are doing before you commit.
- The council puts Mikimoto at 10 minutes and the aquarium at 15 minutes from the terminal, and the aquarium itself says Toba Station is about 10 minutes away, so the three are close together.
