It's actually quite fun, a very novel freshwater fish aquarium that displays not only salmon but also other species like stingrays, chameleons, and carps. A recent activity also includes releasing salmon fry into the river for free. There is a rest stop nearby, selling many local agricultural products, including delicious sashimi, glutinous rice balls, king crab rice balls, a barbecue restaurant, and local farmers growing cheap and delicious strawberries. I highly recommend everyone to go there, as it is fun, educational and fun.
