・A mysterious space that feels like an ancient ruin! "Otani Museum"

The Otani Museum is a representative tourist attraction in the area, where you can experience the historical charm of the stone town of Otani. The predecessor of the Otani Museum is a historic quarry, and the stone used for the main Guanyin statue of Otani Temple came from here. The museum not only preserves detailed information about the mining technology, tools and historical data of Otani Stone, but also allows visitors to visit the spectacular underground space covering an area of ​​approximately 20,000 square meters and 30 meters deep. The dark, quiet and solemn atmosphere of the ruins make it look like a mysterious underground temple, making it a popular filming location for movies, music videos, dramas and even concerts. The Otani Stone, which once supported the local architecture and culture, now continues to tell the historical heritage of "Stone Town" in this space.

・Japan's proud underground shrine for disaster prevention, "Tokyo Outer Suburb Discharge Channel"

This spectacular facility, known as the "huge underground temple," is amazing for its overwhelming spatial beauty! You are welcome to walk into this miraculous project and experience its magnificence and shock for yourself! The so-called "Metropolitan Area Outer Drainage Channel" is a large underground drainage system built under National Highway 16. It consists of multiple facilities, including inflow facilities that draw water from various rivers, underground waterways for storing or diverting water, and drainage airports that discharge water to the ground. The entire system works together to prevent flood disasters, making it a world-class example of disaster prevention engineering. This time we have arranged a popular itinerary! Guided Tour of the Underground Temple: This guided tour takes you to visit the core facility, the "pressure regulating tank". The whole tour takes about 55 minutes, including a brief introduction to the facility by a professional tour guide, and free time for the tour.

※Note: The park will be temporarily closed when the water pump is in operation.
