The event in a few words

Have you always dreamed of running in the Land of the Rising Sun? 🌅 In September, pack your bags 🧳—we’re inviting you to Japan 🇯🇵, in the Osaka Prefecture, in the Yodogawa district for the Yodogawa Ecomarathon 🏃‍♀️.

If you’re more of a solo type 🧍‍♂️, come run the half-marathon or the timed 10 km; if you’re more into family running 🧑‍🧑‍🧒‍🧒, a parent-child 5 km race is organized. The races will start at exactly 11am 🕚, in the heart of Osaka, along the Yodo River. You’ll follow its riverbed via the bike path 🚴‍♂️. As the route is flat, easy, and fast ⚡️, the race is open both to novice runners and seasoned runners looking to beat their personal record 💪. With a participant cap of 300 people, you won’t have to elbow your way through at the start 😝.

Alongside several other sporting events organized, particularly in the prefectures of SaitamaOsakaHiroshimaKyoto and Kumamoto (but mainly in Tokyo 🌸), the Ecomarathon positions itself as an organization concerned about the environment 🌳 and committed to various causes 🎗️. This year, it is possible to donate to the international refugee support organization : Second Harvest Japan. As Japan’s first food bank, the organization is committed to ensuring that everyone has access to food 🍲.

The city of Osaka has a complex history, but has managed to evolve and reinvent itself over the years while maintaining its importance as a central and important city in the country. It is a very touristy destination that combines traditional and modern culture 🎐. Whether you're interested in gastronomy, shopping, culture, or entertainment, you should find what you're looking for in Osaka 😍. If you choose to extend your stay, why not visit the Shin-Osaka Station Museum to learn more about the trains that connect the prefecture. If you're looking for a bit more tradition, don't hesitate to try the Sentō (public baths) or Onsen (traditional hot baths). To learn more about Shinto culture, the Kazaki Shrine ⛩️ will answer all your questions 🧐.

So, tempted? Book your ticket ✈️, lace up 👟—we’ll be waiting for you at the Yodogawa Ecomarathon 🎏.

Discover Japan 🇯🇵
If you've never been to Japan, running the Yodogawa Ecomarathon is the perfect opportunity to discover this country that blends tradition and modernity at every turn. If you decide to extend your stay, we invite you to explore the city of Osaka far and wide. Between Osaka Castle 🏯, the Kaiyukan Aquarium 🦈, or the Onsen / Sentōs 🚰, these attractions are all more famous than the next.

The maximum number of participants is 300 people. If you're used to international races with several thousand participants, you'll see it's not the same buzz! But don't worry, we guarantee you'll have just as much (or maybe even more) fun running 🏃‍♀️.

During your stay, explore and visit local markets to discover and taste 😋 fresh produce, seafood 🦪 and other local specialties. If you walk past a street stall, don't hesitate to try kushitasku 🍢—you'll tell us all about it!
A flat and fast course ⚡️
You might be surprised by how easy and fast the 10 km course is. In fact, it might help you beat your personal record 🏅. If you're hoping to spend a Sunday with the family, a parent-child race is organized for children under 15 🧑‍🧑‍🧒‍🧒.
