Race Day Weather

Average Temperature7.5°C / 46°F
Humidity79%
Wind25.4 km/h
Rain Chance45%
Typical ConditionsCool, often damp mid-March weather on the Sea of Japan coast, typically around 5-10C at the 9:00 AM start with brisk San'in coastal wind; both the 2025 and 2026 editions ran in rain, so showers are a real possibility.

What to Prepare: Plan for cold and wet rather than mild spring: a long-sleeve base, light gloves and a throwaway rain layer for the exposed Sand Dunes start. The coastal opening kilometres are windy, so a wind-resistant top earns its place even if the forecast looks dry.

Wind Impact on Race Day

Wind at 25.4 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.

Frequently Asked Questions

When and where is the Tottori Marathon 2027?

The Tottori Marathon 2027 is projected for Sunday, March 21, 2027, with a 9:00 AM start. The 2027 date is not yet officially announced; it is projected from the recurring pattern, since the race fires on the third Sunday of March (the 2024, 2025 and 2026 editions were all third Sundays). It is a one-way course in Tottori City on the Sea of Japan coast, starting at the Tottori Sand Dunes (Oasis Plaza) and finishing at Yamata Sports Park Stadium, running through the San'in coast and Inaba Man'yo countryside.

How do I enter, and is there a lottery?

There is no lottery: entry is first-come, first-served, and registration closes once the cap is reached. The full marathon is the only distance, with a single field of 4,000 runners, so the spots can go quickly. Entry is online through RUNNET, and the domestic fee is 13,000 yen including insurance (overseas runners pay 20,000 yen, with a separate small foreign quota). The entry window typically opens in mid-to-late autumn, so set a calendar reminder and apply early rather than waiting.

What is the time limit and how strict is the course?

The time limit is 6 hours from the 9:00 AM gun, with the finish closing at 3:00 PM, measured at staffed checkpoints along the route. That is firmer than Japan's most relaxed 7-hour marathons, so it suits a runner confident of a sub-6 finish more than a pure walker. The course rolls gently through the countryside rather than climbing one big hill, so use our pace calculator to set checkpoint splits that keep you safely inside the cutoffs.

Is the Tottori Marathon a Boston-qualifying race?

No. The course is certified by the Japan Association of Athletics Federations (JAAF / Nihon Rikuren koonin), so your official chip time is accurate and valid for Japanese events, but a Japanese domestic road certification is not an Abbott World Marathon Majors or Boston Good-for-Age qualifier, and the race makes no Boston-qualifying claim. If chasing Boston is your goal, check your standard with our Boston qualifying calculator and target a certified BQ race instead.

What makes the Tottori Marathon distinctive?

Three things set it apart. It starts at the Tottori Sand Dunes, Japan's largest dune field, so the opening kilometres run beside the Sea of Japan. It is the only JAAF-certified full marathon in Tottori Prefecture, the least-populous of Japan's 47 prefectures. And it is known for the country's highest volunteer-participation rate, with finishers receiving a finisher medal sand-cast from local Tottori sand. Aid stations serve regional treats such as Tottori pears, rakkyo and Hoshizora-mai rice onigiri.

Do I need a visa to run as a foreign visitor?

Many nationalities, including US, UK, EU and Australian passport holders, 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. Tottori is reached via Tottori Airport (flights from Tokyo Haneda) or by limited express train along the San'in Line, so allow extra travel time from the major hubs compared with a big-city race.

How are the date and entry details usually confirmed?

The Tottori Marathon is an annual March race that resumed in-person running in 2024 after a 2020 cancellation and 2021-2023 online-only editions. Each year's official date, fee and entry window are published on the official site and RUNNET, with most editions landing on the third Sunday of March. Because the 2027 page was not yet live as of mid-2026, treat March 21 as a projection and re-check the official site before booking travel.
