[Correction & Apology: Mandatory Gear for the 50km Category]
There was a discrepancy between the official race guidelines and the participant guide regarding the 50km mandatory gear—specifically items (8) Headlamp and (9) Mobile Battery. While the participant guide listed them as "recommended," the official race guidelines state they are "mandatory." The participant guide has been corrected to reflect the official race guidelines.
We sincerely apologize for the confusion and appreciate your understanding.

A Musical Journey in Our Historic Outdoor Venue

Did you know about the legendary “BEATCHILD” festival that rocked Minamiaso?
The outdoor music theater Aspecta in Minamiaso was the site of Japan’s first all-night rock festival on August 22-23, 1987. The event brought together the top artists of the Japanese rock scene at the time. Initially planned for an audience of 30,000, ticket sales eventually exceeded a whopping 70,000! The venue was packed with young people from their teens to their thirties.
The lineup included iconic artists such as THE BLUE HEARTS, RED WARRIORS, Yasuyuki Okamura, Takako Shirai & CRAZY BOYS, HOUND DOG, BOΦWY, THE STEREET SLIDERS, Yutaka Ozaki, Misato Watanabe, and Motoharu Sano with THE HEARTLAND. The event was later immortalized in a documentary film, “Baby, Are You Okay? BEATCHILD 1987,” released in 2013.

Today, the legendary Aspecta serves as the main venue for the Minamiaso Caldera Trail. Why not take a moment to soak in the majestic scenery of Aso, while feeling the echoes of this legendary event under your feet?

Cycling, Trekking, and Farming Adventures in Our Backyard

For those of you who still want to move your body, we recommend activities where you can fully enjoy the great outdoors of Minamiaso!

Cycling
At the “Activity Center Minamiaso” located in “Asobo no Sato Kugino”, there is a bicycle rental service. The exhilarating feeling of cutting through the wind on a bicycle is exceptional. You can enjoy the unique scenery of Minamiaso, whether you’re touring the water sources or aiming for the top of Mt. Aso. They have everything from simple basket bicycles to e-bikes, and the electric assist makes it easy to ride. It’s a fun experience for everyone, from those who don’t usually ride bicycles to serious cyclists with their own bikes.

For more details on the bicycle rental, click

Trekking
Mennoishi Trekking is a popular trekking course where you aim for a cave shaped like a cat, passing through forests and rocky areas. In recent years, it has been visited by many cat lovers as a popular cat spot. The stone that was once famous as the “stone that doesn’t fall” fell during the Kumamoto earthquake, but miraculously it didn’t break and remains on the trekking course. Now it’s known as the “substitute stone” that fell instead of job-hunting students and examinees, and it’s a power spot!

Farming Experience
At “Minamiaso Farm Camp”, we offer guided tours to showcase the culture and nature of Aso in the great outdoors. This includes crafts, and activities to immerse yourself into Minamiaso life. You can enjoy a leisurely walk through the countryside while feeling the seasons, “hand spinning of Japanese cotton” where you spin thread from cotton, and “herbarium” where you can use a variety of dried flowers, including roses from Minamiaso, in various crafts.
