Typhoon “Jangmi” made landfall in the southern part of Wakayama Prefecture in Japan on the morning of June 3rd, causing over 850 flights to be canceled and multiple bullet trains and railways to be suspended or delayed due to strong winds and continuous heavy rain. The Japan Meteorological Agency has issued a “special warning of river flooding,” urging people to take immediate life-saving actions.
The Japan Meteorological Agency has urged the public to remain vigilant and guard against landslides, river flooding, flooding in low-lying areas, and coastal waves disasters, advising against unnecessary outings to ensure life safety. Residents in areas threatened by flooding should move to buildings above the second floor or higher for shelter if they are unable to evacuate safely.
As Typhoon “Jangmi” moves northward, heavy rain continues to affect the Tokai, Kanto, and Tohoku regions of Japan. Meteorological data shows that as of 6:00 a.m. on the 3rd, hourly rainfall in Omaezaki City, Shizuoka Prefecture reached 57.5 millimeters, while Miyakejima in the Izu Islands recorded 48.5 millimeters of rain, and Owase City in Mie Prefecture accumulated 473 millimeters of rain in the past 12 hours.

The Meteorological Agency predicts that within the next 24 hours, rainfall in the Tokai and Kanto regions may reach 200 millimeters, while the Tohoku region could experience up to 120 millimeters of rainfall. Moreover, the formations of “linear rainbands” in the Tokai, Kanto, and Izu Islands regions could lead to more intense rainfall, highlighting the need to be vigilant about disaster risks.
In addition to heavy rain, strong winds and high waves pose threats to various parts of Japan. The average maximum wind speeds are forecasted to exceed 20 meters per second in Shikoku, Kinki, Tokai, Kanto, Chubu, Izu Islands, and the northeast region on the 3rd, with maximum gusts reaching up to 35 meters per second (approximately 126 kilometers per hour).
Furthermore, wave heights along the Izu Islands and Kinki coasts could reach up to 9 meters, while the Kanto and Tokai regions and the northeast may experience waves reaching 8 meters, with the Tohoku and Shikoku regions expecting waves up to 6 meters.
