Natural disasters are incredibly common in Japan. Earthquakes, tsunamis, and floods are all a significant part of the country due to its geographical location and climate. While we learned of Japan’s preparedness for earthquakes and tsunamis, one area that truly fascinated me during my time in Japan was the country’s approach to flood prevention. Flooding is a serious concern in many parts of Japan, especially during the rainy season and typhoon months. We learned in lectures that the combination of dense urban development, low-lying areas, and heavy rainfall can quickly lead to devastating outcomes. During our stay in Tokyo, we had the opportunity to visit a water intake facility that plays a major role in the city’s flood management system. What we learned there gave me a whole new appreciation for the scale and sophistication of Japan’s infrastructure.
Our visit to the water intake facility began with demonstrations that helped us visualize how quickly flooding can occur and how overwhelming it can be when not managed properly. Seeing simulations of heavy rainfall and rising water levels made it easier to understand just how rapidly water can accumulate in urban areas. Equally fascinating were the models that showed how the system diverts water away from high-risk zones. These visual presentations were engaging and informative, but nothing could compare to actually seeing the system in person. The most impactful part of the visit was when we were taken forty meters underground to explore the massive tunnels where flood water is diverted. We had just learned about the size and scale of these tunnels, but nothing prepared me for what it felt like to stand inside them. I was dumfounded by the magnitude of these tunnels. This hands-on experience allowed me to grasp the immense effort Japan puts into disaster preparedness. I was grateful that it hadn’t rained that day, which meant we were able to safely enter the tunnels. Had there been rainfall, the tunnels would have been off-limits due to their real-time flood management functions.
Visiting the flood prevention facility was not only educational but sincerely impressive. It was a reminder of how essential infrastructure is in protecting communities from natural disasters such as flooding. It was fascinating to learn how Japan has engineered infrastructures to better protect their communities from natural disasters. A monumental takeaway from my time in Japan was that their predisposition to natural disasters was significantly combatted by these measures.
