AquaWorld Oarai (Ibaraki Prefecture Oarai Aquarium) has most species of sharks and largest sunfish tank in Japan.

A young couple of clawless otters are now on exhibit at Sendai Umino-mori Aquarium. There are only 3 facilities hold and exhibit clawless otters in Japan. We can't meet them except at those precious facilities!

I visited South Korea for four days. Needles to say, the purpose is to watch otters!!
