FAQ

When are the roads closed?

On the 2026 (21st race) map, the Seisho Bypass from Seisho-Ninomiya IC to Enoshima-iriguchi on Route 134 is closed in both directions from about 8:00 AM to 3:45 PM, the down line of the Shin-Shonan Bypass from Chigasaki-nishi IC to Chigasaki-kaigan IC from about 8:00 AM to 2:00 PM, and the venue area plus the road from Oiso-nishi IC to Kokufu-hongo on Route 1 from about 6:00 AM to 4:30 PM (same as 2025). Part of the Pacific Coast cycling road near the venue is also closed.

When do the runners pass?

According to the 2026 map: Karagahara 9:10 AM–2:00 PM, Takahamadai 9:20 AM–1:30 PM, Yanagishima 9:25 AM–1:20 PM, Hamasuka 9:40 AM–12:35 PM, Hamamiyama Koban-mae 9:45 AM–12:25 PM, and Oiso-nishi IC until about 3:20 PM. To cheer along the course, walk from Hiratsuka, Chigasaki, Tsujido or Katase-Enoshima Station.

Can I get to Enoshima?

Around the Enoshima-iriguchi junction both directions close from about 8:30 AM to 12:00 PM, but Enoshima can be reached from the Kamakura side. It cannot be reached via Route 134 from the Chigasaki/Fujisawa side.

Can I cross Route 134 on foot?

Assume the street-level crosswalks are not usable during the closure. The blue dots on the map are footbridges over and underpasses beneath Route 134 (OSM survey) that should stay usable. They are not the official crossing guide, so follow staff directions on the day.

Can I drive to the venue?

There is no parking at or near the venue, and the organizers ask that you not be dropped off by car. Oiso Prince Hotel parking is for hotel guests only. Free shuttle buses run from Oiso and Ninomiya Stations on the JR Tokaido Line. In 2025 JR East also ran a "Shonan International Marathon" limited express.

Will it be canceled for weather?

If high waves or strong winds force a cancellation, it is announced at 5:00 AM on the official website, Facebook and X, and at 6:00 AM on FM Yokohama (84.7 MHz).

Who do I contact?

Shonan International Marathon office (0466-21-6667, 10:00 AM–5:30 PM, closed weekends and holidays). On the day, follow police and staff directions for closures and detours.
