About Komakkero

Komakkero lives in the Komaba Pond.

One day, Komakkero found a hat while taking a walk. Komakkero tried putting it on and…Voila!

Komakkero became able to speak Japanese!

The ginkgo leaf on Komakkero’s tummy is the symbol of the Komaba Campus.

It is in the perfect season to see the beautiful ginkgo leaves that the Komaba Festival is held.

Komakkero is a frog but has a tail.

This represents college students, who have characteristics of both a child and an adult.
