Takamori Spring Tunnel Park

Takamori Spring Tunnel Park is an amusement park built inside a 2-kilometer tunnel with wooden walkways, where spring water flows at 32 tons per minute through natural rock formations. The structure allows visitors to walk alongside the water while exploring the mountain's interior.

The site began as an abandoned railway project when workers uncovered substantial underground water sources during the initial excavation. This accidental discovery eventually led to its transformation into a leisure destination.

Seasonal decorations transform the tunnel throughout the year, with lanterns adorning the space during the Tanabata Festival in July and festive displays appearing during the Christmas season. These temporary touches connect the natural setting to local celebrations and give visitors a sense of community involvement in the space.

The park sits about ten minutes on foot from Takamori Station on the Minami Aso Line. The tunnel interior maintains a constant temperature of roughly 17 degrees Celsius throughout the year, making it comfortable to walk through.

At the tunnel's end, visitors encounter a natural waterfall where spring water emerges directly from mountain bedrock with significant force. This dramatic point where water bursts from the stone creates a striking contrast to the quiet walk through the passage.
