Classification

Sodium Chloride-Sulfate-Bicarbonate spring

A lightly mineralized simple thermal spring (676 mg/kg dissolved solids), gentle on the body. Weakly alkaline, it has the soft, slippery feel of the Japanese beauty-water family. A generous 180 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterward.

About

A beloved hot spring cherished by locals as a place of relaxation. In front of the facility is a park with playground equipment and blooming flowers, serving as a resting place for the local community. The bathhouse is semi-underground, with payment at the entrance followed by descending stairs. There are no walls between the changing room and the bathing area, reflecting the traditional Beppu style. It is said that Emperor Keikō, the 12th emperor, once recuperated here. The ceiling is high, and the walls are painted in a soft pastel green. Small tiles cover the floor, evoking a nostalgic and charming atmosphere. Sunlight streams in during the day, creating a bright and comfortable environment. The oval-shaped bathtub is divided in the middle into hot and lukewarm baths. Enjoy the soft water while chatting with regular visitors.

96. Shinoyu Onsen, Beppu ★★★ An old-school onsen for ¥200. Opening hours are listed as 07:00 to 10:30 and 14:30 to 22:00. They stamp the Beppu Onsen-do stamp, and the 88 Kyushu Onsen stamp. An OYUCA card was issued for this onsen. Staff are sometimes present. No shower. The onsen itself strikes the right balance between old-school worn-in condition and a minimal level of modern comfort. The ceilings are high, and it feels very cozy and comfortable in the bath. Especially when sunlight comes straight through the upper windows and reflects on the bath. Two adjoining indoor baths with clear water, at 41.5 and 42 degrees. It is easy to breathe inside. A benchmark, top-tier old-school onsen. A must-visit in Beppu. 30.04.2024 03.04.2025 03.01.2026
