As the 2026 Aichi-Nagoya Asian Games enter their second half, Typhoon Surigae, the 26th typhoon of the year, is heading toward the Pacific coast east of Honshu, where Aichi Prefecture is located.

According to the Japan Meteorological Agency (JMA) today (September 27), Typhoon Surigae was moving north-northeast at a speed of 15 km/h from waters south of Okinawa as of 6:00 a.m. today.

It has a central pressure of 975 hPa, with maximum sustained winds near the center of 35 m/s and peak gusts reaching 50 m/s.

The JMA forecasts that the typhoon will develop as it moves northward and approach Okinawa Prefecture and the Amami Islands in Kagoshima Prefecture by September 29 while maintaining a strong intensity.

Strong winds have already begun in Okinawa Prefecture, with the JMA projecting maximum sustained winds of 23 m/s and peak gusts of 35 m/s for today.

With wave heights expected to reach 6 meters, Okinawa Prefecture has issued warnings, urging sufficient caution against high waves, strong winds, and landslide disasters.

Depending on the typhoon's track, Okinawa could see heavy, warning-level rainfall, with the JMA forecasting up to 80 mm of rain in some areas over the 24-hour period leading up to 6:00 a.m. on September 28, followed by another 80 mm of torrential rain in the subsequent 24 hours.

Because its future path remains fluid, it is not yet clear whether the typhoon will deliver a direct blow to Aichi Prefecture, where the Asian Games are being held, but rain clouds from the typhoon could blanket the region.

According to the JMA's projected path map, the typhoon is expected to come closest to the Chubu region, including Aichi Prefecture, between October 1 and 2, close to the closing ceremony (October 4).

It is also expected to affect the metropolitan area, including Tokyo.

If the typhoon makes a direct hit on the metropolitan area, there are concerns that Chiba Prefecture—which is in the midst of recovery following successive "record-breaking torrential rain" damages—could suffer further water damage.

Chiba Prefecture experienced record-breaking downpours in mid-August and early September, and recently suffered damage from Typhoon Dujuan, the 25th typhoon.

Kyodo News reported that special vigilance is required for Chiba and Kanagawa prefectures, which have already suffered significant damage from heavy rains brought by Typhoon 25.

Meanwhile, separate from Typhoon Surigae, rain forecasts are in place for wide areas of Honshu today—from southwestern Kyushu to the Chubu region—due to the influence of an autumn rain front.

In particular, the JMA has emphasized the need to be on guard against landslide disasters, flooding, and overflowing rivers as linear rain bands (concentrated heavy rain zones) could form in Nagasaki, Fukuoka, Kumamoto, Saga, and other areas.
