Odawara Castle Hydrangea and Iris Festival

A mix of two beautiful flowers — hydrangeas and irises — in the same color scheme turns Odawara Castle into a pastel paradise.

What happens?

The grounds of Odawara Castle will be sprinkled with more than 10,000 irises and 2,500 hydrangeas. They contrast beautifully with the brilliant red bridge in Odawara Castle Ruins Park.

Schedule 2023

Everday the flowers will be lit from sunset (around 7 p.m.) till 8:30 p.m. On the weekend during the festival, food trucks and stalls will open in front of Hanashobu Square. There will also be concerts and performances. We’ve highlighted the main events below. Some may be canceled if it rains.
