Typhoon Jangmi Update: The Typhoon Has Arrived in Japan

As of the morning of June 2nd, Typhoon Jangmi (referred to as Typhoon No. 6 in Japan) has begun to affect southern Japan during its journey northeast, moving close to the Amami Islands after passing through the Okinawa area. Wind gusts exceeding 40 meters per second have been reported in various locations.

The Japan Meteorological Agency (JMA) has warned that the typhoon will move northward before gradually turning east. That means that many areas in western Japan and along the Pacific coast face, including several major cities, face the risk of heavy rainfall, strong winds, high waves, and possible disruptions to air travel and railway services. Experts believe this weather should continue through June 2nd, peaking on June 3rd before the typhoon dissipates.

Traveling in Japan? These Are the Regions to Watch Out For

• Ryukyu Islands (Okinawa and Amami Islands): On June 2, severe winds, high waves, coastal surf, landslides, flooding in low-lying areas, rising river levels, and possible river overflow are expected.
• Western Japan (Kyushu, Shikoku, Kansai, including Fukuoka and Osaka): Between June 2~3, the forecast calls for very strong winds, high waves, heavy rain, flash flooding, and landslides.
• Pacific Coast of Eastern Japan (Tokyo, Kanagawa, Shizuoka, including Yokohama and Izu): On June 3, adverse weather conditions and heavy rainfall may affect transportation and travel.

Important Information for Travelers in Tokyo

Although Tokyo is located some distance from the center of the typhoon, heavy rain and strong winds are still possible throughout the Kanto region. The typhoon’s main rain cloud bands are spread across the northern and eastern sides of the storm, rather than being concentrated solely around its center.

For those currently in Tokyo, the latest forecast indicates that the strongest impacts are likely to be felt on June 3rd. If you’re in the area, watch out for heavy rain, strong winds, and possible disruptions to train and air travel, and most of all—stay safe. We recommend closely monitoring announcements from the Japanese Meteorological Agency, and if you’re planning to take any kind of transportation (whether June 3rd is your departure date, or you just planned to catch a train across the city), check the official websites/social media of the operators in case service is canceled. If you need to, check with your airline before departure, and verify that trains are up and running before you head out in the rain!
