In April 2026, Seibo was officially announced as the charity partner for the “Tokyo Yamathon,” organized by the International Volunteer Group (IVG) and we are now making various promotion for the event!

What is the Yamathon?
The Yamathon is a charity event where teams walk or run the entire circuit of the JR Yamanote Line. Through participation fees and sponsorships, we partner to create a lasting social impact across the globe.

By providing school meals in Malawi, we aim to connect the kindness of people in Japan to the future of Africa!

Join us in making a difference
Leading up to the event, we are planning to share special messages from Malawi for our sponsors, participants, and supporters.

Why not join us in running through the heart of Tokyo while connecting with children across borders who are building the future of Africa?
