Yamanakako Tourism Association is taking advance reservations for its August “sunflower flights.” The experience is an early-morning tethered ascent at Yamanakako Community Plaza Kirara, not a free-flight balloon journey, and weather can interrupt or cancel operations.
Key Facts For Travelers
Prices And Participation Rules
The official page lists JPY 5,000 for adults of junior-high-school age and older, JPY 8,000 for inbound international visitors, JPY 3,000 for elementary-school children, and JPY 1,500 for preschool children. Children of elementary-school age and younger must ride with a guardian. Participant parking is free, and each basket carries about five adults.
Weather And Booking
Advance registration is required and places close when capacity is reached. When weather forces cancellation, the organizer says it generally sends email notice around 4:00 PM on the preceding day, but same-day interruption or cancellation is also possible. Pregnant visitors cannot ride, and travelers needing accessibility support should consult the organizer in advance.
Traveler Actions
- Reserve through the official booking link and confirm the exact session time shown there.
- Check email after 4:00 PM on the day before your ride and again before leaving in the morning.
- Dress for a cool, possibly damp lakeside start even during August.
- Allow enough driving time for the early arrival; the venue is about 10 minutes by car from Yamanakako IC.
- Do not assume the flight will operate in marginal wind or weather conditions.
