Setagaya 246 Half Marathon

ACT WOMEN'S RUNning was born in Tokyo in 2017 when founder Emi decided running should feel good, not grueling. This crew of around 20 women dismantles the myth that running is tough and monotonous, instead building a space where movement, conversation, and joy intersect. Twice a month near Shibuya, they explore new neighbourhoods with a warm, curious, and refreshingly low-pressure vibe. Their signature runs start and end at Bunka Yokusen, a public bath in Ikejiri, where the real conversations begin in one of Tokyo's most beloved neighbourhood traditions. Here, running is about discovering health on your own terms.

080Tokyo was founded in March 2017 by Koichi, Higashi, and Nashil with a bold conviction: running connects people across languages and cultures. Based in Tokyo's vibrant Shibuya district, the crew has grown to around a hundred runners from different nationalities and professions who share a philosophy that real communication happens through shared movement. Founded on the belief that sport can solve social problems, 080Tokyo channels this mission into building bridges between young people. The crew's signature Monday evening runs at Yoyogi Park conclude at Hachiman-yu, a neighborhood sento where post-run conversations reveal the true heart of the community. For 080Tokyo, the run is just the beginning.

Pacer Track Club emerged in Tokyo in April 2017 when a group of Nike Run Club runners refused to let their community dissolve. Founder Hideaki stepped in to keep the momentum alive, transforming an ending into a beginning. Today, the crew counts around forty members, small enough that friendships run deep but large enough that every session brings genuine push and accountability. Their philosophy is straightforward: make running both faster and more fun, proving that speed and joy aren't opposing forces. Training at Oda Field inside Yoyogi Park, Pacer Track Club builds structured sessions where honest effort and good company converge on one of Tokyo's finest athletic tracks.
