Record Rainfall in Akita and Flooding of the Koyoshigawa

A rapidly deepening low-pressure system with an associated front tracked from the Sea of Japan to the Sea of Okhotsk, funneling developed rain clouds into northern and eastern Japan's Sea of Japan coast. Akita Prefecture bore the brunt, recording the heaviest October rainfall since records began: the 24-hour total through midnight on the 22nd reached 136.5 mm at Yashima in Yurihonjo City and 119 mm at Tazawako in Semboku City. Japan Meteorological Agency radar analysis estimated that approximately 300 mm fell in the same 24-hour window near Yurihonjo.

The Koyoshigawa river running through Akita Prefecture was confirmed to have overflowed its banks at a point in Yurihonjo City on the night of the 21st. The JMA and the Ministry of Land, Infrastructure, Transport and Tourism jointly issued a Level 5 Flood Emergency Warning (氾濫特別警報), but as water levels fell they downgraded it to a Level 2 Flood Advisory at 2:20 a.m. on the 22nd. According to the Akita Prefectural Police, as of 12:30 a.m. on the 22nd no injuries or damage to homes had been confirmed in Yurihonjo. Residents were nonetheless urged to stay away from dangerous areas due to the continued possibility of inundation.

Critical PHP Vulnerabilities Trigger Wave of Service Suspensions

Two critical vulnerabilities were discovered in PHP, the programming language widely used to power websites. The PHP development organization announced it would release a patch at 11 p.m. Japan Standard Time on the 21st, and the Information-technology Promotion Agency (IPA) urged web operators using PHP to take prompt action. IPA stated it had not confirmed any active exploitation at this stage but warned that attacks could occur in the future.

In response, companies and universities moved quickly to protect their systems. Snack maker Koikeya (湖池屋) and Shizuoka University took their websites offline. Miyagi Prefecture-based Shichijushichi Bank suspended some of its services, and major publisher Kodansha (講談社) suspended its online manga reading service.

Food Consumption-Tax Bill and Diet Developments

On the 21st—marking one year since the Takaichi (高市) Cabinet took office—Prime Minister Takaichi said "the challenge of year two begins," identifying further measures against global inflation as the top priority and vowing to deliver the results of key policy shifts "to every corner of Japan." The food consumption-tax reduction bill, designated a priority piece of legislation by the administration, was explained by Finance Minister Katayama in the House of Representatives Finance Committee on the 21st; substantive debate is scheduled to begin on the 23rd.

The ruling bloc hopes to build a careful deliberative record and win opposition support to pass the bill through the lower house, but opposition parties are demanding that Prime Minister Takaichi appear before the committee, that joint hearings be held with other committees, and that the scope of eligibility and funding sources for the support payments be disclosed early. Coordination among opposition parties is expected to continue. Separately, the Liberal Democratic Party is considering a proposal to reduce the number of lower-house seats by 31 in line with population decline, aiming to reach a conclusion by the end of this month; the matter is also expected to come up on the 22nd in cross-party talks on electoral system reform.

Typhoon No. 30 Approach and National Weather Outlook

Large and violent Typhoon No. 30 is moving westward east of the Philippines. Outer rain bands and strong winds are already reaching Okinawa's Sakishima Islands, and seas in the area are running very rough. The typhoon is expected to approach the Sakishima Islands with a gale zone between the 23rd and 24th, and there is also a possibility it could turn eastward and approach Kyushu early next week; the public has been urged to monitor the latest forecasts closely.

In the Honshu region, the front is expected to push east on the 22nd, allowing high pressure to bring sunny intervals to many areas. After the previous day's southerly winds had produced near-summer temperatures, a shift to northerly winds will bring noticeably cooler conditions. In Hokkaido, a strong cold air mass aloft will bring November-like temperatures, with cold rain and snow on the Sea of Japan side and a risk of snowfall in mountain passes and highland areas. Forecast high temperatures for major cities: Naha 28°C, Kagoshima 27°C, Tokyo / Osaka / Hiroshima / Matsuyama / Kochi 25°C, Nagoya 24°C, Kanazawa 19°C, Nagano 17°C, Akita 15°C, Sapporo 10°C—considerably lower than the previous day across much of the country.
