What to Prepare: Early-autumn Niigata is comfortable racing weather, but the riverside and seafront stretches are exposed; a light long-sleeve you can shed plus a throwaway top layer at the start handles a cool morning or a passing shower.

Wind at 22.7 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.

Use Calculator →The 42nd Niigata City Marathon is held on Sunday, October 11, 2026, with an 8:30 AM start. The course starts in front of Denka Big Swan Stadium and finishes at the Niigata City Track and Field Stadium, looping through central Niigata along the Shinano River and the Sea of Japan coast.
There is no lottery: full-marathon entry is first-come, first-served and closes as soon as the field fills. Online registration runs from early April to late June through the official site and RUNNET, and the general full-marathon fee is 12,500 yen. With a 9,000-runner cap, popular slots can sell out before the deadline, so sign up early. Set a realistic goal first with our race time predictor.
Yes. Niigata sits on the flat delta of the Shinano River, so the marathon has only about 10-30 m of total elevation change, with the only real bumps coming at river bridges and the Niigata Minato undersea tunnel. It is one of the more PR-friendly autumn courses in Japan. Build your target splits with our pace calculator.
The cutoff is a comfortable 7 hours, finishing at 15:30. Combined with the flat profile and good aid stations, that makes Niigata a sensible choice for a first marathon or a comeback race. Use our finish time calculator to confirm you can clear the limit at your training pace.
Yes. The course is certified by both World Athletics and the Japan Association of Athletics Federations (JAAF / 日本陸連公認), so an official chip time can be used for Boston qualifying if you meet your age-group standard. Check where you stand with our Boston qualifying calculator.
Niigata showcases the waterfront city: you cross the historic Bandai Bridge over the Shinano River (Japan's longest river), run along both riverbanks, pass through the Niigata Minato undersea tunnel and run within sight of the Sea of Japan, with Sado Island on the horizon on clear days. The race is part of the larger Niigata RunFes weekend.
Many nationalities (US, UK, EU, Australia and others) can enter Japan visa-free for short tourist stays; confirm your own nationality's rule before booking, as Japan does not currently use an ESTA or eTA. Niigata is about two hours from Tokyo on the Joetsu Shinkansen, making a race-weekend trip straightforward.
