Tokyo Marathon 2026: A Celebration of Runner's Challenge

On March 1, 2026, the Tokyo Marathon will take center stage, welcoming 39,000 runners to participate in a monumental event. Seiko Group, the official timer since the inaugural marathon, is committed to enhancing this year's experience with four unique initiatives aimed at showcasing each runner's challenge. The Tokyo Marathon is a coveted event within the Abbott World Marathon Majors series, renowned for its prestige and competition. Seiko plans to utilize its precision timing technology not only to record times but to amplify the runners' journeys—transforming moments into cherished memories.

Initiative 1: SEIKO HOUSE - A Window of Support

Located at the 33-kilometer mark on the marathon course, the SEIKO HOUSE in Ginza will feature a special window display showcasing the names of all 39,000 runners. Echoing the spirit of encouragement, this initiative aims to greet runners with a motivational “GO!” as they pass by. This year’s theme visually captures the footprints and tire tracks of the participants, symbolizing their relentless effort leading up to the marathon. This location will become a symbol of triumph, welcoming the exhilaration before the race and sharing in the pride after finishing.

Runners can capture a memorable photo with their personal timer, marking their journey towards their personal goals. This activation allows not just runners but also their families and friends to partake in the excitement, making the experience more communal and supportive.
