Frequently Asked Questions

When is the Tokushima Marathon 2027?

The Tokushima Marathon 2027 is set for Sunday, March 14, 2027, the event's 20th edition, with a staggered wave start from around 8:20 a.m. in central Tokushima City. As it debuts a redesigned route, confirm the exact date and start time on the official site before booking travel.

How does the 2027 course differ from before?

2027 introduces a reborn course that runs mostly through downtown Tokushima (city streets rise to about 60%) and finishes inside Pocari Sweat Stadium, reducing the long Yoshino River embankment that defined earlier editions to roughly 20% while keeping a scenic riverside section. The profile stays largely flat. Use our pace calculator and race time predictor to plan even splits.

Is the Tokushima Marathon a Boston qualifier?

Earlier editions were run on a course certified by World Athletics, AIMS, and the Japan Association of Athletics Federations (公認), making finish times valid for Boston qualifying. The 2027 route is new and its certification is being finalized, so verify the current status before counting on it, then check the standard for your age and gender with our Boston qualifying calculator.

What is the time limit and entry fee?

For 2027 the time limit is being shortened to 6.5 hours (from the previous 7), with staggered checkpoints along the route. The full-marathon entry fee has recently been 11,000 yen (about 2,000 yen more for a commemorative shirt); confirm the final 2027 fee and entry window on the official site.

How do I enter the race?

Entry is handled online, typically through RUNNET, with registration opening in the autumn before the March race. Recent editions have used first-come (先着順) registration up to roughly 8,500 places rather than a lottery, so apply early. Always check the official site for the exact 2027 method and dates.

Do I need a visa to travel to Japan for the race?

Many nationalities (US, UK, EU, Australia) can enter Japan visa-free for short tourist stays - confirm your own nationality's requirement before booking. Japan does NOT currently require an ESTA or eTA. Tokushima is reached via Tokushima Awaodori Airport, or by bus across the Akashi-Kaikyo Bridge from Kobe and Osaka, roughly two to three hours from the Kansai region.
