MIMARU, a leading apartment hotel brand in Japan under Cosmos Hotel Management Co., Ltd., is observing a clear evolution in travel behaviour as international marathon participants increasingly convert race trips into full-scale group holidays involving family members, friends and travel companions.

Data from MIMARU indicates that almost 80 per cent of guests staying at its Tokyo Shinjuku property during the Tokyo International Marathon period are runners taking part in the event. A significant portion of them arrive with companions, reshaping what was traditionally a solo athletic journey into a shared travel experience with broader leisure purposes.

With Japan continuing to record strong inbound tourism growth, marathon-related travel is expanding beyond the race itself. Cities such as Tokyo, Kyoto and Osaka are seeing visitors structure longer itineraries around major running events, combining athletic participation with sightseeing, cultural exploration and quality time with accompanying guests.

“For many travelers, the marathon is just one part of the journey,” said Mao Mochizuki, International PR at MIMARU. “One person may be running, but everyone is exploring Japan together. The race becomes a reason to travel, spend time together and experience new places.”

Japan’s marathon industry has steadily transformed into one of the strongest pillars of the country’s experience-led tourism economy, attracting a growing number of international runners who seek more than just competitive sport. The nation’s unique combination of world-class race organisation, advanced infrastructure, and culturally rich destinations has positioned its marathon calendar as a major global attraction. Today, these events function not only as athletic challenges but also as immersive travel gateways into Japan’s diverse urban and regional landscapes.

A key driver behind this expansion is Run Japan, operated by R-bies Co., Ltd., which serves as a centralised platform for international participants. It provides structured access to marathon listings, entry guidance, and essential logistical information for races held across the country. Beyond administrative support, the platform actively promotes Japan as a holistic travel destination where sporting events seamlessly integrate with cultural exploration. Through its network, international runners can plan journeys that combine race participation with curated travel experiences, ensuring that each visit extends far beyond the finish line.

Among Japan’s most recognised races, the Tokyo Marathon stands as a flagship event on the global running calendar. The course takes participants through a meticulously designed urban route that showcases the capital’s modern identity while passing through iconic districts and high-energy commercial zones. The race reflects Tokyo’s dual personality—technologically advanced yet deeply rooted in tradition—offering runners a vivid contrast of futuristic skylines and historic neighbourhood pockets. Its scale, organisation, and international participation have made it one of the most prestigious marathons in the world.

In contrast, the Kyoto Marathon delivers a completely different experience, defined by calmness, heritage, and cultural depth. The route guides runners through a landscape shaped by centuries of history, including traditional temples, sacred shrines, and serene residential districts. Unlike the high-speed urban energy of Tokyo, Kyoto offers a reflective journey where participants are constantly surrounded by architectural heritage and natural beauty. This combination makes it especially appealing to travellers seeking a more contemplative race environment that connects sport with cultural immersion.

The Osaka Marathon introduces yet another dimension to Japan’s running landscape. Known for its vibrant atmosphere, Osaka offers an energetic and expressive race environment where local communities play an active role in supporting participants. The course reflects the city’s reputation as Japan’s culinary capital, with neighbourhoods famous for street food culture, entertainment districts, and lively public engagement. The strong presence of spectators along the route enhances the sense of momentum, making it one of the most emotionally charged marathons in the country.

For many international runners, participation in these events becomes the foundation for extended travel itineraries. Rather than treating the marathon as a single destination activity, visitors often design multi-city journeys that allow deeper exploration of Japan’s cultural and geographical diversity. The well-established “Golden Route,” connecting Tokyo, Kyoto, and Osaka, remains the most popular framework for such travel plans. This corridor offers a balanced introduction to Japan’s modern innovation, historical heritage, and urban vibrancy within a single connected journey.

Beyond the Golden Route, travellers frequently extend their stays to explore additional regions that offer unique marathon experiences and scenic diversity. Coastal areas associated with the Shonan International Marathon provide a refreshing contrast, combining ocean views with relaxed suburban environments. Similarly, Nara stands out as a culturally significant extension point, known for its ancient monuments, heritage parks, and traditional atmosphere. These regional additions enrich the overall travel experience, transforming marathon participation into a multi-layered cultural journey.

This evolving pattern reflects a broader transformation in global tourism behaviour. Increasingly, travellers are prioritising experiences that combine purpose, activity, and cultural engagement rather than conventional sightseeing itineraries. Marathon tourism fits naturally into this shift, offering structured events that serve as anchors for broader exploration. Participants are encouraged to move beyond race-day performance and engage more deeply with local communities, everyday life, and regional identity.

Accommodation trends in Japan have also adapted to this rising demand. Apartment-style hotels and serviced residences are becoming particularly popular among marathon travellers due to their flexibility and comfort. These facilities allow groups of runners and their companions to stay together in shared living spaces, providing practical benefits such as kitchen access, relaxation areas, and extended-stay convenience. This setup supports pre-race preparation, post-race recovery, and continued travel without logistical disruption.

As a result, Japan’s marathon ecosystem has evolved into a fully integrated tourism model that connects sport, culture, and regional discovery. The combination of world-class races, structured travel platforms, and adaptable accommodation options ensures that marathon tourism continues to grow as a defining element of Japan’s international appeal.

“As travelers look for more memorable and meaningful experiences, marathon travel is becoming a new way to experience Japan,” said Mochizuki. “It’s no longer just about crossing the finish line. It’s about sharing the journey with the people you travel with.”
