Saitama Marathon 2027

Because registration is already open and popular Japanese marathons often fill up or use a lottery, enter as early as possible. Confirm the official entry deadline, payment deadline, and whether capacity limits apply to the Marathon, Premium, Beginner Support, Enjoy Aid, or Team categories. If you need a hotel near GMO Arena Saitama, book it at the same time as your entry, since race weekend accommodation in Saitama Shintoshin and Omiya can sell out quickly.

The start and finish are in front of GMO Arena Saitama, also known as Saitama Super Arena. Expect athlete check-in, bib collection, and a race festival area near the venue. Arrive early to allow time for security checks, bag drop, warm-up, and finding your start corral. Corrals are usually assigned by estimated finish time, so line up according to your expected pace. Listen for announcements and follow marshals’ instructions for the mass start.

The course is a certified city marathon route on roads, starting and finishing in front of GMO Arena Saitama. It passes landmarks including Saitama Stadium 2002 and Urawa Komaba Stadium. Expect urban streets, aid stations, and crowd support, with possible mild inclines or bridges typical of a city marathon. After you cross the finish line, follow the flow to receive your finisher items, water, and any food or recovery support, then collect your bag and exit the finish area.
