Ibaraki Robots Aquarium
A special aquarium in collaboration with the Ibaraki Robots has been introduced! This time, in hopes of the Ibaraki Robots' further success in the B.LEAGUE PREMIER, we will be exhibiting the mudskipper, which has the habit of jumping on land. In addition, around the aquarium will be a special Ibaraki Robots corner, where life-size panels of players and balls autographed by Komazawa players will be on display.

Exhibition Date | Saturday, May 2025, 2 - Sunday, June 1, 3 |

Exhibition place | 3rd floor Shark Daddy's Room |
Exhibited creatures | Southern mudskipper |

Southern mudskipper
Perciformes, Gobiidae
Total length is about 7 cm. It lives in brackish water and around mangroves on the coast. Its gills are pouch-shaped, so it can store water. It can also breathe through its skin, so it can live on land for long periods of time by keeping its body moderately wet. It has developed muscles at the base of its pectoral fins, so it can crawl onto land, hop around, and climb mangrove branches.
Sea Lion Walking Time Basketball Challenge

For a limited time only, we will be holding a basketball challenge during the sea lion walking time in collaboration with the Ibaraki Robots! Don't miss the scene where the California sea lion receives a pass from the zookeeper and performs a brilliant trick!
