Strong winds swept across Japan on Monday during the Golden Week holidays, causing disruptions to transport services and prompting weather warnings nationwide [1]. A rapidly developing low-pressure system moved eastward across the country and intensified as it passed over the Sea of Japan [1].
Heavy rain and gusty winds began late Sunday evening, first affecting western Japan before spreading into the Kinki and Kanto-Koshin regions by Monday morning [1]. Wind gusts reached near-gale or gale-force levels in multiple areas, impacting travel and outdoor activities [1].
The Japan Meteorological Agency reported a maximum instantaneous wind speed of 28.5 meters per second (102 kilometers per hour) in Chiba shortly after 6 a.m. Monday, noting that this level of wind is difficult for a person to stand against without holding onto something [1]. Other high gusts included 26.9 meters per second in Gotemba, Shizuoka Prefecture, and 24.7 meters per second in Yokohama [1].
Authorities issued weather advisories across affected regions as the low-pressure system moved eastward. Travel services adjusted schedules and warned passengers of possible delays due to the strong winds.
The gusty conditions and rain were expected to ease gradually after Monday, with the low-pressure system moving away from the main islands. Transport services planned to restore normal operations once conditions improve.
