Tropical Storm 'Bebah' Batters Vast Regions of Japan

Tropical Storm Bebah Slams Japan, Threatening Major Flooding Across Multiple Regions

Tropical Storm Bebah made landfall on Japan's Shikoku Island early Friday morning, bringing the threat of catastrophic flooding and landslides across vast areas of the country. The storm is expected to dump unprecedented rainfall amounts—up to 300 millimeters in 24 hours—as it tracks eastward along Japan's Pacific coast, potentially affecting millions including residents of Tokyo.

Storm's Path and Immediate Impact

Japanese meteorological officials report that Bebah is moving at 25 kilometers per hour across Shikoku Island, with its trajectory set to follow Japan's Pacific coastline eastward. The storm's influence extends far beyond its center, with rain clouds forming across the Tokai, Kinki, and Kanto regions—the latter encompassing Tokyo and its surrounding metropolitan area.

Current rainfall projections show the storm capable of producing 50 millimeters per hour across a broad swath from western to northeastern Japan, with some areas experiencing rates exceeding 80 millimeters per hour, according to Japan's national broadcaster NHK.

Regional Vulnerability and Risk Assessment

Northern Japan Faces Severe Threat

The Tohoku region in northeastern Japan—still bearing scars from the devastating 2011 tsunami—is experiencing particularly heavy rainfall. This area's mountainous terrain and existing infrastructure vulnerabilities make it especially susceptible to the dual threats of flooding and landslides that Bebah presents.

Tokyo Metropolitan Area in Storm's Path

The inclusion of the Kanto region, home to Tokyo's 37 million residents, in the storm's projected impact zone raises significant concerns about urban flooding. Tokyo's advanced drainage systems, while sophisticated, have faced challenges during previous extreme weather events, particularly as climate change intensifies storm patterns.

Japan's Storm Preparedness in Context

Japan's experience with tropical storms and typhoons has led to some of the world's most advanced early warning systems and disaster preparedness protocols. However, climate change is intensifying storm patterns across the Pacific, with recent years seeing more frequent extreme rainfall events that test even Japan's robust infrastructure.

The 300-millimeter rainfall projection over 24 hours represents a significant weather event that could overwhelm drainage systems and trigger widespread evacuations. This volume is particularly concerning given Japan's mountainous geography, where steep slopes can quickly channel rainwater into deadly torrents.

Economic and Infrastructure Implications

Bebah's path along Japan's Pacific coast threatens some of the country's most economically vital regions. The potential disruption to transportation networks, including the critical Tokaido corridor connecting Tokyo, Nagoya, and Osaka, could have ripple effects across Japan's economy and global supply chains.

The storm's timing and intensity underscore the growing challenge that extreme weather events pose to developed nations, even those with sophisticated disaster preparedness infrastructure like Japan. As Bebah continues its eastward march, the coming hours will test both Japan's meteorological forecasting capabilities and its emergency response systems.
