重要なお知らせ: 登録内容の変更とサポートについて

For the Tokyo Yamathon, we use RUNNET to manage all event registrations. RUNNET is a widely-used platform in Japan for race and endurance event sign-ups, offering participants an easy way to register, handle payments, and access event details.

Please Note: RUNNET is not an IVG-Japan service. We use RUNNET just like many other running, walking and endurance events in Japan, which means we do not own, manage the platform or have access rights to your registration data .

As a result, we cannot make any changes to your registration information, such as team details, name adjustments, or other support requests.

If you need to update your registration or require support, you must visit your registration page on RUNNET and request help through their services. Since we do not have access to RUNNET’s internal systems, we cannot guarantee a timely or satisfactory response to your requests—this is entirely up…

Question: Can I Walk with My Child in the Tokyo Yamathon?

Yes, children can participate in the Tokyo Yamathon!

This charitable giving walkathon is not only a great way to stay active but also an excellent opportunity for parents to teach their children about community service, volunteering, and the importance of contributing to society. It’s also a wonderful way for parents and children to spend quality time together and bond over a shared challenge.

However, it's important to note that parents or guardians are fully responsible for the care and well-being of their children during the event. While we believe the Yamathon offers a positive and rewarding challenge, it’s crucial for parents to use sound judgment.
