Seiryū Cave

Seiryū Cave is a limestone cave in Kitakyushu that stretches horizontally through the earth with spacious passages carved by water over countless years. The underground chambers display different sections, each showing various rock formations and cave features along the pathway.

This cave formed over an immense span of time as water slowly filtered through the limestone and carved out passages beneath the surface. The process began millions of years ago and continues to shape the underground structure that visitors walk through today.

The name Seiryū refers to the blue dragon in Japanese tradition, reflecting the local reverence for water and natural forces that shaped this underground realm.

The underground remains cool year-round, so bring warm clothing and sturdy shoes for safe walking on potentially slippery ground. A light jacket is recommended since temperatures stay cold inside regardless of the season outside.

The cave entrance displays striking stalactites hanging from the ceiling, formed by mineral-rich water seeping through stone over thousands of years. These hanging formations reveal the patient work of water drop by drop in creating these delicate geological features.
