What Visitors Can Do

The tourism association lists a dahlia-harvest experience and flower-themed workshops, alongside a stamp rally with a prize draw. The program also includes fair-style stalls and live sessions, making it a hands-on event rather than only a flower-viewing day.

Local-specialty food and limited items using edible flowers are planned. Exact availability may change or sell out, so visitors should treat individual menu items and activities as subject to event-day operation.

Admission And Timing

The official listing gives admission as JPY 600 for adults and JPY 240 for elementary and junior-high students, with free admission for Yamanakako residents. Parking is listed as available, but the event page does not specify a parking fee in its basic-information table.

The park opens one hour before the festival and closes 90 minutes after it. Arriving early gives time to orient yourself, but festival activities begin at 9:30 AM and finish at 4:00 PM.

Weather And Flower Expectations

Light rain does not automatically cancel the event, while severe weather does. Bring hands-free rain protection and check the official page before departure if the forecast is uncertain.

Flower condition depends on weather. The event schedule confirms the program, but it does not guarantee a particular bloom level or an unobstructed Mt. Fuji view.

Traveler Actions

  • Visit between 9:30 AM and 4:00 PM for festival activities on September 12.

  • Check the official event page before departure if severe weather is possible.
