Detailed Comparison

Course profile and race-day feel

The Hokkaido Marathon rolls through central Sapporo on a flat course with roughly 30 m of elevation gain concentrated in a gentle hill during the first 5 km. After that, the route flattens through tree-lined boulevards and Nakajima Park. The course itself is not the challenge -- the August heat is. Expect sweat-soaked roads, frequent aid stations handing out sponges and ice, and a field that visibly slows after the halfway mark. Hokkaido's 20,000 runners share a festival energy that feels more like survival camaraderie than a race.

Kobe Marathon adopted a brand-new course from 2025 that eliminated the infamous 38 km bridge climb. The new route follows the Seto Inland Sea coastline from central Kobe to Akashi's Okura Beach, then returns to finish at Kobe Harborland -- with a total elevation change of just 10 m. This makes Kobe one of the flattest marathons in Japan. Autumn conditions (12-17 C) are close to ideal for distance running, and the coastal views of the Akashi Kaikyo Bridge and Awaji Island give the race a scenic identity few Japanese marathons can match.

Entry strategy

Hokkaido uses first-come, first-served registration -- not a lottery. Entry opens in late March and sells out within days. If you miss the general window, charity entries and official travel packages remain available. At 16,500 JPY for domestic runners (22,000 JPY for international), it is one of the more affordable major Japanese marathons.

Kobe uses a lottery system. In 2026, 23,836 runners applied for 20,000 full-marathon slots -- roughly 1.2:1 odds, far gentler than Tokyo's 10:1. Registration opens in spring with results announced by summer. At 15,000 JPY, it is competitively priced. Neither marathon requires a qualifying time.

Weather and what it means for your time

Hokkaido's August conditions -- 20-26 C with humidity regularly above 70 percent -- will slow you down. In 2023, the start-line temperature hit 30 C and the completion rate dropped sharply. Even experienced runners should expect to add 15-30 minutes over their cool-weather PR. This is a heat-adjusted effort, not a time-trial.

Kobe's November weather is near-perfect for racing. Temperatures of 12-17 C with moderate humidity and coastal breezes create the kind of conditions that produce personal bests. Combined with the new flat course, Kobe 2025 onward is positioned as a serious PR-hunting option for runners across Japan.

Travel and trip-building

Sapporo in August doubles as a food destination. Miso ramen, fresh seafood from Nijo Market, Sapporo beer, and the nearby lavender fields of Furano make it an easy trip to extend. Flights from Tokyo take 90 minutes, and the city is walkable.

Kobe in November offers its own culinary identity. Kobe beef, Nada-district sake breweries, and the Chinatown district of Nankinmachi sit within walking distance of the finish line at Harborland. Osaka and Kyoto are 30 minutes away by train, making Kobe easy to combine with a broader Kansai trip. Use our What to Wear tool to plan race-day kit for either climate.

Who should pick which

Choose Hokkaido if you want a unique summer marathon challenge in Japan, enjoy festival atmosphere over fast times, or are building a Sapporo trip around the race. It rewards heat-adapted runners who treat the race as an experience rather than a PB attempt.

Choose Kobe if you want a serious shot at a personal best on one of Japan's flattest courses, prefer comfortable autumn racing, or plan to combine the race with Kansai-region travel. The new course makes Kobe especially appealing for runners targeting a fast time without the brutal lottery odds of Tokyo or Osaka.

Frequently Asked Questions

Is Hokkaido Marathon harder than Kobe Marathon?

Hokkaido's August heat (20-26 C, often higher) is a greater challenge than Kobe's flat November course. Heat impacts every kilometer and can add 15-30 minutes to your finish time. Kobe's new course has only 10 m elevation change, making it physically easier in ideal autumn conditions. Plan your pacing with our Heat Adjustment Calculator if running Hokkaido.

Can I set a personal best at Kobe Marathon?

Yes. Kobe adopted a new flat course from 2025 with only 10 m of elevation change and autumn temperatures of 12-17 C. These are close to ideal PR conditions. The old course had a difficult bridge climb at 38 km that is now eliminated. Kobe is now one of the strongest PR-course options in Japan outside of the major city marathons.

How do I enter Hokkaido Marathon before it sells out?

Hokkaido uses first-come, first-served registration (not a lottery). Entry opens in late March and sells out quickly. Set a reminder for the official site opening date, and register through the Hokkaido Marathon app for early-bird access. Charity entries and travel packages may remain available after general registration closes.

What are the lottery odds for Kobe Marathon?

Kobe Marathon's lottery is relatively gentle. In 2026, roughly 23,800 runners applied for 20,000 slots -- approximately 1.2:1 odds. This is far easier than Tokyo Marathon (10:1) or Osaka Marathon. The lottery results are announced in summer after spring registration closes.

Which marathon is better for international visitors to Japan?

Kobe is more convenient for international visitors. It is 30 minutes from Osaka by train with easy connections to Kyoto, Nara, and the wider Kansai region. November weather is comfortable for sightseeing. Hokkaido requires a domestic flight to Sapporo, but rewards the extra effort with unique summer culture -- beer gardens, fresh seafood, and lavender season.

Can I run both Hokkaido and Kobe Marathon in the same year?

Yes, and it makes a strong seasonal double. Hokkaido is in late August and Kobe in mid-November, giving you roughly 11 weeks of recovery and training between races. Use Hokkaido as a heat-condition challenge and Kobe as your autumn PR attempt. Plan your training split with our Training Plan tool.

How does Hokkaido Marathon's heat compare to other summer races?

Hokkaido is Japan's only major summer full marathon. Temperatures of 20-26 C are milder than tropical marathons but the humidity (often above 70 percent) makes it feel worse. In 2023, race-day temperature reached 30 C. The completion rate is notably lower than autumn and winter marathons. Serious heat acclimatization training is essential.
