What this place is
Oga Aquarium Gao (男鹿水族館ガオ, Oga Suizokukan Gao), officially Akita Prefectural Oga Aquarium, is a public aquarium located along Oga Peninsula coast, Oga, Akita Prefecture, Japan. GAO stands for Globe, Aqua and Ocean, and sounds like an Oga native Namahage shout.

Why it is worth the trip
- A main tank large enough to show schooling fish and big pelagics moving naturally.
- Species collected from the surrounding sea, so the line-up differs from other Japanese aquariums.
- Feeding times and training sessions where staff explain what the animals are doing and why.
What you can do here
- Check the daily schedule on arrival and plan around feeding and show times.
- Sit at the big tank for ten minutes — it is the one exhibit that rewards patience.
- Visit the touch pool for starfish, urchins and rays, especially good with children.
- Watch a dolphin or sea lion session; front rows may get wet, which is part of the fun.

Getting there by public transport
Good to know before you go

- Weekend afternoons are busiest — mornings are calm and the animals are more active.
- Tanks are cold and dim; bring a layer even in summer.
