As part of the Tokyo Marathon 20th Anniversary project, “Support for 100% Race Completion,” Tokyo Marathon 2027 has introduced “WWS (Workout Well-being Scorer),”Checked by Netwell System Corporation, a Supporting Partner, to help participating runners monitor their physical condition as they prepare for the race.
WWS allows users to use the camera on a PC, tablet, or smartphone to capture an image of their face for approximately 30 seconds and displays estimated health indicators such as heart rate and stress levels. The service can be used to support day-to-day condition management.
It can also be used as a self-checking tool for runners to monitor their condition during the training period and help them participate in the race without overexerting themselves.
■Service Availability
The service will be available from October 5, 2026.
If you are interested in using the service, please access it through “Helpful Links for Runners” in My Entry.
*Use of this service is voluntary.

Through this initiative, we aim to support runners in monitoring their condition as they prepare for the Tokyo Marathon 2027 and help create an environment in which they can participate safely and comfortably.
