Check out these pearly eyes and fluffy body.

The adorable sea otters are popular starTs at Toba Aquarium in Mie Prefecture.

Visitors were able to see them as much as they wanted. However, that will change…

Toba Aquarium PR / Visitors will have to be in line and take turns every minute. 

They will now have a one-minute cap on the time they can watch the adorable creatures. 

Fukuoka, Fukuoka Prefecture

The cap comes after a male sea otter that was kept at an aquarium in Fukuoka Prefecture died in January 205.

Toba Aquarium expects there will be more visitors now that it is the only aquarium in Japan where people can see sea otters. 

The playful otters at Toba Aquarium can catch toys…

Spin with a cone and do much more. 

Toba Aquarium PR / The visitors will not have to queue in a straight line, so they can see from between other people. Practically, they will have more than a minute to see the sea otters.

Visitors will also be allowed to “line up” for the sea otters multiple times a day.
