Race Day Weather

Average Temperature7.5°C / 46°F
Humidity79%
Peak Wind25.4 km/h
Rain Chance45%
Typical ConditionsMid-March weather on the Sea of Japan coast can be cold and wet. Check the race-week forecast and prepare for wind and rain during the wait before the 9 a.m. start.

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.

Frequently Asked Questions

When and where is the Tottori Marathon 2027?

Tottori Marathon 2027 takes place on Sunday, March 14, 2027, starting at 9:00 AM JST. The official 2027 requirements now confirm both the date and start time. The one-way course starts near Tottori Sand Dunes Oasis Plaza and finishes at Yamata Sports Park Stadium; the finish closes at 3:00 PM.

How do I enter, and is there a lottery?

Entry is first-come, first-served through RUNNET, from October 14, 2026 at 00:00 JST to December 11 at 23:59 JST, or earlier at capacity. The published field is 4,200. Domestic entry costs 13,000 yen including insurance; the official requirements list overseas entry at 20,000 yen, plus entry fees. Check the separate overseas route before applying: the organizer says its quota is separate, while RUNNET describes the 4,200 total as including foreign runners.

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 some Japanese marathons with seven-hour limits, 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?

The course is JAAF-certified, which meets the B.A.A. requirement for certification by the national distance-running governing body in the host country. An official marathon result may be submitted for Boston qualifying if it meets the applicable time standard and qualifying window, subject to B.A.A. verification. Meeting a qualifying standard does not guarantee entry. Check your age-group standard with our Boston qualifying calculator.

What makes the Tottori Marathon distinctive?

Three things set it apart. It starts at the Tottori Sand Dunes, one of Japan's largest dune areas, 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. Local volunteers support the race, and finishers receive a 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 2027 date, start time and entry window are now published in the official event outline and on RUNNET, race ID 397497. Follow those current documents rather than extrapolating from past editions: the race is March 14, 2027 at 09:00 JST, with first-come entry from October 14, 2026 at 00:00 to December 11 at 23:59 JST, or earlier at capacity.
