Mount Yufu - Active Volcano Hiking Guide

Mount Yufu rises 1,583 meters above Japan's hot spring capital, where you can climb an active volcano in the morning and soak in geothermal waters by afternoon. This twin-peaked stratovolcano in Oita Prefecture delivers one of Kyushu's most rewarding day hikes—challenging enough to feel accomplished, accessible enough for motivated beginners.

Known locally as Bungo Fuji for its symmetrical cone, this volcanic giant combines exposed ridges, forest trails, and chain-assisted scrambles with views spanning Beppu Bay to distant mountain ranges. The mountain sits active, monitored, and safe to climb, with thermal springs at its base reminding you of the volcanic forces beneath your boots.

You'll discover detailed trail routes for both summit peaks, seasonal conditions that transform the landscape from azalea-covered slopes to winter ice challenges, and practical logistics for reaching the trailhead from Beppu. Learn the gear you need, the best times to climb, and how to combine your summit push with Yufuin's famous onsen culture. Whether you tackle the technical West Peak or choose the shrine-topped East Peak, this guide prepares you for a safe, memorable volcanic adventure.
