Strong winds and rain from a low-pressure front disrupted transport and caused power outages across eastern Japan on May 14 and 15, 2024 [1].

The timing of the storm coincided with Golden Week, one of Japan's busiest travel periods, creating significant delays for tourists and commuters across the Kanto region [1].

Transport infrastructure faced widespread failures as wind speeds peaked. In Chiba, the maximum instantaneous wind speed reached 25.1 m/s [3]. These conditions forced the closure of the Tokyo Bay Aqua-Line in the early morning of May 15, 2024 [2].

Air and rail travel were similarly impacted. Narita Airport saw flights affected, while several railway services were suspended, including the JR Narita Line, the Keiyo Line, and the Musashino Line [1]. The suspensions left many travelers stranded at stations. One commuter said, "The inside of the train was packed and it was terrible," while another said their group meeting was scheduled for 7:30 but it was already 9:00 [1].

Beyond transport, the storm caused structural damage and utility failures. In Matsuda-cho, Kanagawa, the winds were strong enough to blow off a metal roof from a parking lot [1]. The weather system also triggered power outages affecting more than 6,000 households [2].

The impact extended to local businesses. A reporter said some convenience stores were forced to stop operations because of the power failures [1].

“The inside of the train was packed and it was terrible”

The disruption highlights the vulnerability of Japan's highly integrated transport network to sudden weather events, particularly during peak travel windows like Golden Week. When primary arteries such as the Tokyo Bay Aqua-Line and major JR lines fail simultaneously, the lack of immediate alternatives creates rapid congestion and systemic delays across the Kanto region.
