Yokoze Onsen Saitama is a natural hot spring in Yokoze, a town in Chichibu District, Saitama Prefecture, Japan, a mountainous rural community in the upper Aru River valley at the foot of the Chichibu mountains, known for its wild wisteria, autumn foliage, and traditional connections to the horse-breeding culture of the ancient Musashino plateau. The naturally bicarbonate-rich spring waters here, within a long thermal tradition, are associated with well-being and relaxation thanks to their gentle alkaline character, offering a soothing soak in a quiet mountain town setting that preserves much of the traditional rural character that has shaped Saitama's western mountain communities for centuries. Yokoze's combination of scenic mountain valley landscapes, seasonal nature beauty, and the unpretentious wellness of natural bicarbonate hot spring bathing provides an ideal countryside retreat for visitors seeking peaceful Saitama highlands relaxation.

Insider tip — Tucked into the Chichibu highlands west of Tokyo, Yokoze Onsen draws water from deep mountain aquifers that produce a silky bicarbonate flow ideal for sensitive skin. The forested valley setting means mornings arrive with mist rolling off the Arakawa river gorge. Arrive early on weekdays to secure an outdoor tub before day-trippers from the capital fill the rotenburo.
