In April 2023, the biotope situated in a corner of Shinjuku Chuo Park in Tokyo marked its 20th anniversary. Yoshie Itamoto, 80, heads up the Shinjuku Chuo Park Biotope Association, which has overseen the biotope since its establishment.

Itamoto extols the appeal of the biotope as a small piece of 'great nature' in the city. "We hope many children will visit the biotope," she says.

"They come to this pond from nearby residential areas and other fenced-off areas of the park to lay their eggs," Itamoto explained. I also saw the gelatinous remains of eggs floating nearby, telling me the tadpoles were just newly born.

A school of Japanese rice fish (medaka) rested above a flat stone in the water. Butterbur and other plants and flowers were growing around the pond, and butterflies fluttered in the air.
