The event in a few words

Have you always dreamed of running in the Land of the Rising Sun? 🌅 In November, 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 11:00 a.m. 🕚, in the heart of Osaka, along the Yodo River. You’ll follow its banks via the bike path 🚴‍♂️. As the route is flat, easy, and fast ⚡️, the race is open both to novice runners and to experienced runners looking to beat their personal best 💪. With a participant cap of 300 people, you won’t have to elbow your way through at the start 😝.

With several other sporting events organized, particularly in the prefectures of SaitamaOsakaHiroshimaKyoto and Kumamoto (but mainly in Tokyo 🌸), the Ecomarathon positions itself as an environmentally conscious 🌳 and committed to different causes 🎗️. This year, it is possible to donate to the international refugee support association : Second Harvest Japan. As Japan’s first food bank, the organization is committed to ensuring 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 food, 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 your shoes 👟—we’ll be waiting for you at the Yodogawa Ecomarathon 🎏.

4 reasons to join this race

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 in every way. 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.
Take part in a human-scale event 👫
The maximum field 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 (and maybe even more) fun running 🏃‍♀️.
Taste Japanese specialties 🍱
During your stay, explore and visit local markets to discover and enjoy 😋 fresh produce, seafood 🦪, and other local specialties. If you pass by 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 may even help you beat your personal best 🏅. If you’re hoping to spend a Sunday with the family, a parent-child race is organized for children under 15 🧑‍🧑‍🧒‍🧒.
