Hinuma Hydrangea Festival

Festival highlights

The highlight is the colorful array of flowers across the Valley of Hydrangeas at Hinuma Nature Park.

In 2026, around 30 varieties and 10,000 hydrangea plants were featured, along with “Hydrangeas & Umbrellas,” a wind-chime path, and a photo contest.

On event days, performances by local junior high schools, kindergartens, and nursery schools are joined by local specialty sales, food, and workshops.

One distinctive feature is that visitors can enjoy both flowers and local events in the same park.

Origins and History of Hinuma Hydrangea Festival

Hinuma Nature Park fully opened in Heisei 7.

The Valley of Hydrangeas originally had relatively few plants, so hydrangeas donated by the town’s flower growers’ association were planted there.

The Hinuma Hydrangea Festival began in Heisei 22, when around 10,000 flowers came into bloom.

2026 marks the 16th festival.

Official information
