The Kyoei Mukoyama Tunnel is a unique two-story tunnel located near Yoro Keikoku in Chiba Prefecture. Originally, the upper Mukoyama Tunnel was a hand-carved tunnel. To improve convenience, the lower Kyoei Tunnel was constructed, resulting in the unusual two-tiered structure visible today. When entering from the bus street side, you can observe the old tunnel above the new one. The tunnel is known for its photogenic qualities, with the light creating a beautiful green hue in photos. It's easily accessible by bus from Yoro Keikoku Station, making it a worthwhile stop for tourists exploring the area.
