The sight of goldfish swimming peacefully in a glass bowl provides a momentary coolness on a hot and humid summer day.
In the past, goldfish were extremely popular in the Edo castle town, and so Edo became known for the raising of goldfish.
Within the city, Edogawa Ward, which was one of the leading goldfish production areas in the country until the late 1950s to early 1960s, is still counted among the three major goldfish producing areas.
The Edogawa Goldfish Festival is held every year in late July.
There are usually over 20 varieties, including the Edogawa Ryukin and Ranchu, on display and sale at the venue (Edogawa Ward Gyosen Park).
There is also a goldfish-scooping booth set up for children. At times besides the festival, you can purchase goldfish at fisheries within Edogawa Ward.
