Last Updated: August 17, 2026
These Terms of Use (“Terms”) apply to the use of Jumful, a travel and experience booking service operated by KOYA Inc. (“we,” “us,” or “our”).
By using this website or making a booking through Jumful, you agree to these Terms.
1. About Jumful
Jumful provides travel information and a platform through which users (“Customers”) can discover and book experiences offered in Hiroshima and surrounding areas.
Experiences may be provided directly by KOYA Inc. or by independent businesses, organizations, guides, instructors, facilities, or other service providers (“Experience Providers”).
The specific conditions applicable to each Experience, including its price, schedule, meeting point, participant requirements, cancellation policy, and other important information, are displayed on the relevant Experience page.
2. Eligibility to Make a Booking
You may make a booking through Jumful without creating a user account.
When making a booking, you agree to provide accurate, complete, and current information.
If you make a booking on behalf of other participants, you are responsible for providing them with all relevant information regarding the Experience and these Terms.
If a participant is a minor, the booking must be made or authorized by a parent, guardian, or other person legally authorized to provide consent where required.
We may refuse or cancel a booking if the information provided is false or incomplete, if payment cannot be processed, if the booking violates these Terms, or if we reasonably determine that accepting the booking would create a safety, legal, or operational concern.
3. Booking and Confirmation
A booking is made by completing the booking process specified on the relevant Experience page.
A booking is considered confirmed when you receive a booking confirmation from Jumful or when otherwise indicated during the booking process.
For Experiences provided by an independent Experience Provider, the Experience itself is provided by that Experience Provider under the conditions stated on the relevant Experience page.
Please review all booking details carefully before completing your booking.
4. Prices and Payment
Prices are displayed on each Experience page in Japanese yen (JPY) and include applicable consumption tax unless otherwise stated.
Payment for bookings made through Jumful is accepted by credit card only.
Payment is generally processed at the time the booking is made.
Any additional costs not included in the Experience price, such as transportation to the meeting point, admission fees, equipment rental, meals, or other expenses, will be indicated on the relevant Experience page where applicable.
Customers are responsible for any fees charged by their credit card issuer, including foreign transaction or currency conversion fees.
5. Cancellations by Customers
Cancellation policies vary by Experience.
The cancellation policy displayed on the relevant Experience page at the time of booking applies to your reservation.
Depending on the timing of your cancellation, a cancellation fee of up to 100% of the Experience price may apply.
Failure to attend an Experience without prior notice (“no-show”) may result in no refund.
By completing a booking, you acknowledge that you have reviewed and agreed to the applicable cancellation policy.
6. Changes or Cancellations by Jumful or an Experience Provider
An Experience may be changed, postponed, or cancelled due to severe weather, natural disasters, transportation disruptions, safety concerns, illness or unavailability of the Experience Provider, insufficient participants where a minimum number is required, or other unavoidable circumstances.
If an Experience is cancelled by Jumful or the Experience Provider and cannot be rescheduled, you will receive a full refund of the amount paid for the cancelled Experience.
If an Experience must be modified, we will make reasonable efforts to notify you using the contact information provided at the time of booking.
Unless otherwise required by applicable law, Jumful and the Experience Provider are not responsible for additional travel-related expenses resulting from a change or cancellation, including transportation, accommodation, airfare, or other personal expenses.
7. Customer Responsibilities
Customers are responsible for reviewing the details and participation requirements of an Experience before booking.
You agree to:
- Arrive at the designated meeting point at the specified time
- Follow reasonable instructions provided by the Experience Provider
- Follow applicable laws, regulations, safety rules, and local requirements
- Provide accurate information relevant to participation
- Inform us or the Experience Provider of any circumstances that may materially affect your ability to participate safely where appropriate
- Behave in a manner that does not endanger, disturb, or cause unreasonable inconvenience to other participants, Experience Providers, local residents, or third parties
An Experience Provider may refuse or discontinue participation if a Customer’s behavior creates a safety risk, seriously disrupts the Experience, violates applicable laws, or materially breaches these Terms.
In such circumstances, the Customer may not be entitled to a refund.
8. Travel and Participation
Customers are responsible for making their own travel arrangements to and from the meeting point unless transportation is expressly included in the Experience.
Customers are also responsible for ensuring that they have any documents, clothing, equipment, insurance, or other items required for their travel or participation.
Some Experiences may involve outdoor activities, physical activity, weather conditions, interaction with nature, food or beverages, or other inherent risks.
Please carefully review the description and requirements of each Experience and make your own decision as to whether the Experience is appropriate for you and other participants included in your booking.

The latest version of these Terms will be published on this website together with the date of the most recent update.
Where consent to a change is required by applicable law, we will obtain such consent as required.
16. Severability
If any provision of these Terms is determined to be invalid, unlawful, or unenforceable, the remaining provisions will continue to remain in effect to the extent permitted by applicable law.
