We went to the Takamori-Yusui Tunnel park at the last of our trip. Before it became a park, the ”Japan National Railways" was constructing a railway here. They found a water resource under the ground while digging a tunnel. Because water prevented to dig the tunnel, the plan was stopped. Now the tunnel is providing water to people in Takamori city. We saw strange objects look like mushrooms in a canal to the tunnel. Now “Takamori Tanabata Festival” is being held inside the tunnel. There were many hand-made decorations in the tunnel. There was an interesting water fountain, Water Pearl, in the most remote part of the tunnel. Please enjoy videos of the Water Pearl. The water looks like flow back.
