Major Typhoon No. 30 is tracking north through the East China Sea and set to approach Kyushu on October 26, with up to 200 mm of rain forecast across wide areas of western and eastern Japan through October 27 due to interaction with a stationary front. In France, 410,000 people joined nationwide anti-inflation protests on October 24, with around 1,000 arrested amid a heavy security deployment. On the sports front, SoftBank defeated DeNA 3–1 in 11 innings in Game 1 of the Japan Series, and figure skater Nakai Ami (中井亜美), 18, came from behind to win the GP Series France event.

## What this episode answers

### What path is Typhoon No. 30 expected to take, and how much rain will it bring to which regions?

Typhoon No. 30 is tracking north through the East China Sea, turning eastward to approach Kyushu on October 26, then expected to merge with a stationary front and bring up to 200 mm of rain to northern Kyushu, Kanto-Koshin, and Shikoku by October 27, with warnings for landslides, river flooding, and strong winds.

### What was the scale and background of the large-scale protests in France, and how did authorities respond?

About 410,000 people joined union-led anti-inflation protests across France on October 24; following the October 17 riots, authorities deployed 70,000 security personnel, directed Paris marchers along routes away from the city center, and arrested roughly 1,000 people nationwide, with Interior Minister Nunez (ヌネス) saying disruption was less than the previous week.

### What mechanism does the new biodegradable plastic developed by the University of Tokyo use, and how effective was it shown to be?

The plastic has decomposition enzymes pre-mixed in and breaks down when its cross-section is exposed to water; placed on the seabed more than 750 m deep off Misaki, Kanagawa, for five months, it decomposed almost completely—more than 30 times faster than enzyme-free biodegradable plastic.

### What were the results of Game 1 of the Japan Series, and who are the starters and key players to watch in Game 2?

SoftBank defeated DeNA 3–1 in 11 innings in Game 1; Game 2 features DeNA starter Ogata Shuto (尾形周都) against SoftBank's Moinelo (モイネロ), with the key question being whether DeNA's lineup—anchored by a hot Maki and a resurgent Tsutsugō—can solve Moinelo after being held to one run in Game 1.

### What were the results on the final day of the Aichi-Nagoya Asian Para Games, and how many total medals did Japan win?

On the final day, the boccia mixed pairs of Takahashi Kazuki (高橋和樹) and Sekine Sayaka (関根沙耶香) won gold by defeating the world-top Singapore pair; Japan finished with a record 186 medals including 64 gold across the seven-day event, which drew roughly 4,000 athletes from 45 Asian countries and territories.

## Typhoon No. 30 Approaches Kyushu; Heavy Rain Forecast Across Western and Eastern Japan

Major Typhoon No. 30 is tracking north through the East China Sea, gradually turning eastward and expected to approach Kyushu on October 26. As of the broadcast (through 5:00 a.m. on the 25th), one-hour rainfall totals reached 32.5 mm in Kochi City, 26.5 mm in Shinkamigoto, Nagasaki Prefecture, and 23 mm in Matsue City. In the hour leading up to 6:00 a.m., an extremely heavy 74 mm was recorded in Kochi Prefecture.

According to the weather forecaster, if the typhoon follows the center of its projected track, it will cross Kyushu during the daytime on the 26th, then transition into an extratropical cyclone off the coast of Shikoku by that evening, merging with a stationary front. The overlap of the stationary front near Honshu and warm, moist air flowing in from the typhoon is expected to trigger widespread heavy rain.

Forecast totals for the 24 hours through tomorrow morning stand at 200 mm for northern Kyushu, 150 mm for Shikoku, 120 mm for the Chugoku region, and 100 mm for the Kinki region and southern Kyushu. For the following 24 hours from tomorrow morning, up to 200 mm is expected for Kanto-Koshin and Shikoku, 150 mm for Kinki and Tokai, and 100 mm for Kyushu. Even after transitioning to an extratropical cyclone, strong winds are expected across a wide area. The public is urged to take strict precautions against landslides, flooding in low-lying areas, and river overflow, and to watch for lightning and gusts from localized cumulonimbus clouds.

## Anti-Inflation Protests Return to France; 410,000 Join, Around 1,000 Arrested

Large-scale protests demanding measures against high prices swept across France on October 24, organized by labor unions. The Interior Ministry announced that approximately 410,000 people participated nationwide.

Following the riots, vandalism, and store looting that occurred during the October 17 protests, authorities deployed around 70,000 security personnel this time in a heightened posture. In Paris, marchers were directed along a route away from the city center, led by fully equipped riot police. One female participant in her 30s said she knew what had happened the previous week but wanted to show she would keep raising her voice. A woman in her 70s said that in France—the land of rights—it had become dangerous simply to take part in a protest.

The Paris march ended with clashes between police and some participants, with water cannons and tear gas deployed. In Grenoble in the southeast, a supermarket was looted, while in Marseille the mayor warned of organized looting attempts via social media. Interior Minister Nunez (ヌネス) announced on the evening of the 24th that approximately 1,000 people had been detained nationwide, while noting that vandalism had decreased compared to the previous week and emphasizing that "advance measures contained the violence."

## Nearly Fully Decomposed at 750 Meters Deep — University of Tokyo Develops New Biodegradable Plastic

A research group at the University of Tokyo and other institutions announced the development of a new biodegradable plastic with decomposition enzymes pre-mixed into the material. A form of microbially degradable plastic, it works by breaking down when its cross-section is exposed to water, activating the embedded enzymes.

In an experiment placing the material on the seabed more than 750 meters deep off Misaki, Kanagawa Prefecture, for five months, it was confirmed to have decomposed almost completely. It also decomposed more than 30 times faster than enzyme-free biodegradable plastic in a comparable experiment. Professor Iwata Tadahisa (岩田忠久) of the University of Tokyo Graduate School of Agricultural and Life Sciences commented that since enzyme-based decomposition was achieved in the harsh deep-sea environment, applications in land environments such as mountains and rivers are also anticipated, and that he hopes commercialization will help address the problem of ever-accumulating waste.

## Japan Series Game 1 to SoftBank; Matsui Named Yomiuri Giants Manager

SoftBank defeated DeNA 3–1 in 11 innings in Game 1 of the Japan Series, taking a 1–0 series lead. For DeNA, Maki (牧) hit a home run among his two hits, and Tsutsugō (筒香)—who had struggled in the Climax Series—also went 2-for, showing signs of recovery. For SoftBank, Masaki (正木), the Climax Series MVP, drove in two runs including the go-ahead hit.

For Game 2, DeNA will start Ogata Shuto (尾形周都)—who was traded from SoftBank mid-season and held opponents scoreless for four innings in the Climax Series Final—while SoftBank will counter with Moinelo (モイネロ), who started Game 1 of the Climax Series and allowed three runs in under three innings. Whether the DeNA lineup, held to one run in Game 1, can solve Moinelo is seen as the decisive factor.

Matsui Hideki (松井秀樹), newly appointed manager of the Yomiuri Giants, spent about an hour inspecting the club's facility in Kawasaki on the 24th, greeting players and staff. While admitting it still "feels strange to be called manager," he said "the feeling that I have to lead from the front is growing stronger," and will take charge of the team beginning with autumn training on October 30.

## Asian Para Games Close; Nakai Ami Claims Come-from-Behind Win at Figure Skating GP

The Aichi-Nagoya Asian Para Games—Asia's largest multi-sport para event and the first ever held in Japan—concluded its seven-day schedule with a closing ceremony in Nagoya on October 24. Roughly 4,000 athletes from 45 Asian countries and territories participated, and Japan captured a record total of 186 medals, including 64 gold. On the final day, the boccia mixed pairs of Takahashi Kazuki (高橋和樹) and Sekine Sayaka (関根沙耶香) won gold by defeating the world-top Singapore pair. The next Games will be held in Doha, Qatar, four years from now.

At the opening leg of the Figure Skating Grand Prix Series, the France event, the women's singles free skate was held, with Nakai Ami (中井亜美), 18, who won bronze at the 2026 Milano Cortina Olympics, staging a come-from-behind victory.
