Race Day Weather

Average Temperature8.5°C / 47°F
Humidity77%
Wind24.9 km/h
Rain Chance27%
Typical ConditionsMild south-Kyushu winter morning, typically 7-12C (45-54F) at the 9:00 start and climbing by midday. Often clear with a sea breeze off Kagoshima Bay, though cold rain or hail can pass through; far gentler than mainland Honshu January races.

What to Prepare: Wear a light long-sleeve you can shed once the open seaside road warms in the sun. Gloves and a throwaway top handle the cool start, and a packable rain layer is smart since a brief shower or hail squall is possible this time of year.

Wind Impact on Race Day

Wind at 24.9 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 is the 2027 Ibusuki Nanohana Marathon?

The 44th edition is scheduled for Sunday, January 10, 2027, with the full marathon starting at 9:00 JST. It is held every year on the second Sunday of January, making it the first big certified-course marathon on Japan's calendar each year.

How do I enter, and is there a lottery?

There is no lottery. Entry is first-come, first-served through Japan's RUNNET portal (and the official site), with a 10,000-runner cap for the full marathon that closes once it fills, typically after registration opens in early August. Create your account early and register on opening day to secure a place. The full-marathon entry fee is 10,000 yen.

Do I need a visa or ESTA to run in Japan?

Japan does not operate an ESTA or eTA system. Many nationalities (US, UK, EU, Australia and others) can enter Japan visa-free for short tourist stays, which covers a marathon trip. Always confirm your own nationality's current requirement before booking, as rules can change.

What is the time limit?

The cutoff is a very generous 8 hours from the gun, the longest of any nationally ranked marathon in Japan. That makes it a realistic finish for first-timers and run-walkers despite the hilly course. Use our pace calculator to find the steady pace that keeps you inside the 8-hour window with margin.

What is the course like and is it Boston-qualifying?

It is a JAAF-certified (陸連公認) road marathon along the Satsuma Peninsula, winding past golden rapeseed (nanohana) fields with the cone of Mt Kaimon ('Satsuma Fuji') and Kyushu's largest lake, Lake Ikeda, in view. The route rolls through the first 10km and climbs a long hill from about 35km (around 100m of change), so it is scenic first and fast second. Because the course is certified, a finishing time here is valid for Boston qualifying; check the standard for your age with our Boston qualifying tool.

How do I get to Ibusuki?

Fly into Kagoshima Airport, then take a bus or train toward Ibusuki at the southern tip of the Satsuma Peninsula (roughly 1.5-2 hours total); the start at the Fureai Plaza Nanohana-kan is about 5 minutes by taxi from Ibusuki Station. Ibusuki is famous for its natural sand baths, an ideal post-race recovery soak, so plan an extra night to enjoy them.
