About the Guide

JMGA Trekking Guide, also UIMLA mountain leader. From the Northern Alps to remote satoyama valleys, my footsteps have taken me across the mountains of Japan. I guide in multiple languages, offering perspectives that go beyond the trail — into the culture, history, and spirit of Japan's mountain landscapes.

Safety comes first, always. Every journey is tailored to your pace and goals, because no two climbers are the same. Whether you're stepping onto a mountain path for the first time or are a seasoned alpine trekker — I'm here to make your encounter with Japan's mountains truly unforgettable.
