The Metropolitan Outer Area Underground Discharge Channel, fondly known as the "Kasukabe Sanctuary," is a remarkable blend of practical flood control infrastructure and captivating tourist destination. Located in Kasukabe, Saitama Prefecture, near Tokyo, this subterranean network plays a crucial role in protecting the city from the ravages of heavy rain and typhoons.
A Symbol of Preparedness
The Kasukabe Sanctuary, a testament to Japan's unique approach to natural disasters, is considered a symbol of anticipation, preparation, and humility. Built to address Tokyo's flood management challenges, this technical structure mirrors a submerged Roman temple, boasting an impressive 6.3 km length and 59 concrete pillars standing 18 meters high.
A Unique Underground Experience
For those seeking an unusual tourist experience, the Kasukabe Sanctuary offers a unique opportunity. The underground chamber features colossal columns, each approximately 2 meters wide, 7 meters deep, and weighing around 500 tons. The architecture creates a fantastical, temple-like atmosphere reminiscent of the Parthenon or underground temples found in Turkey.
Visitors can tour a small accessible area of this enormous facility, taking about 15 to 20 minutes. The internal temperature is maintained around 20°C in summer and 10°C in winter, making it a refreshing cool spot in the heat. Good photographic opportunities are available, although lighting can be dim.
Educational and Interactive
In addition to the underground tour, the RyuQ Museum on the surface offers insights into flood control and showcases materials relating to special effects and drama filming locations, such as command rooms used in movies and TV shows like Shitamachi Rocket. For tech enthusiasts, an AR app allows visitors to simulate water accumulating inside the underground chamber, adding an interactive layer to the visit.

Tours of the Kasukabe Sanctuary usually require reservations and are only available when the facility is not in operation. The site, while not typically mentioned in tourist guides or maps, is popular for its impressive engineering, photo-worthy aesthetics, educational value, and cool environment, making it a recommended stop for visitors to Kasukabe and Tokyo's metro area interested in infrastructure and unique underground spaces.
A World Record Holder
The Kasukabe Sanctuary, being the world’s largest underground flood management system, has saved nearly a billion euros in damages since its full commissioning in 2006. It has prevented estimated damages of over 150 billion yen, demonstrating its effectiveness in cushioning the impact of violent weather.
A Cultural Landmark
