Our guide
Osaka Aquarium Kaiyukan stands in Minato ward near Osaka Bay, next to the Tempozan Ferris wheel. When it opened in 1990 it was the largest public aquarium in the world.
Two things are worth knowing before you go. Ticket prices change by date, and the aquarium recommends buying a date-and-time e-ticket in advance: with a same-day ticket you may have to wait for an entry time. Opening hours also change by date, so check the day on its website. The easiest way there is the Chūō subway line to Osakakō Station, then about 5 minutes on foot from Exit 1 — head for the big Ferris wheel.
Mount Tenpō is about 0.5 km away in a straight line, and Universal Studios Japan about 1.2 km.
