What should have been a joyful Obon holiday was significantly impacted by heavy rain in Kyushu and the Chugoku region, causing major disruptions to Shinkansen operations.
In recent years, prolonged heavy rainfall, such as from “linear precipitation bands,” has increased. JR Central has been conducting experiments at a research facility in Komaki City, Aichi Prefecture, to revise the criteria for suspending operations during such extreme weather.
Here, they are conducting an unprecedented heavy rain experiment—simulating rainfall of 200 mm per hour, far exceeding Japan’s observed record of 153 mm. Under this waterfall-like downpour, they are thoroughly collecting data on how much moisture the embankments can withstand.
Recent rainfall patterns have become more intense. The goal is to assess the current embankments’ resilience under extreme conditions.
