Why Beppu? The Onsen Capital

Nestled between mountains and the sea, its volcanic activity fuels a dizzying array of baths, from steaming pools to colorful springs. Tourists flock to famous sites like Beppu Jigoku Meguri (べっぷ地獄めぐり), but Beppu Onsen Hoyo Land (別府温泉保養ランド【泥湯】) remains a hidden gem, offering a quieter, more primal experience away from the crowds.
The Mud Bath Experience
Stepping into Beppu Onsen Hoyo Land (Mud Bath) (別府温泉保養ランド【泥湯】) feels like entering another world.

This mineral-rich mud leaves your skin silky smooth and is said to treat ailments like rheumatism, skin conditions, diabetes, and even heart issues by boosting blood flow and detoxifying heavy metals.

Bathing Tips, Staying, and Nearby Gems

Bathing Details and Precautions
The onsen features 3 to 4 distinct outdoor mud baths, varying in temperature and texture, all mixed-gender “one of Japan’s last true mixed onsen”. Don’t be shy—embrace the tradition and dive in. Separate men’s and women’s baths are also available for those who prefer privacy. Be cautious: avoid wearing metal jewelry or accessories, as the sulfur will corrode them. The mud’s potent sulfur leaves a lingering smell on skin and clothes for up to a week, so choose your outfit wisely “old clothes are best”. Baths are intense, with high heat retention, so limit soaks to 10-15 minutes to avoid overheating. Note: children under junior high age are prohibited from the mud baths due to their strength.
