What this episode answers
Why does heavy rain remain a danger after Typhoon No. 30 became an extratropical cyclone, and which areas face the greatest risk?
Warm, moist air continues to flow toward the cyclone and its associated front, sustaining heavy rainfall across western and eastern Japan. Shikoku and the Izu Islands face the risk of extremely heavy rain exceeding 50mm per hour, with 24-hour totals of up to 200mm forecast for Shikoku and 150mm for the Izu Islands through tomorrow morning.
What were the results of the Fukushima gubernatorial election, and what is the background and platform of the winner, Uchihori Masao?
Incumbent Uchihori Masao (62) won his fourth term, capturing over 90% of valid votes and defeating six newcomers by a wide margin. A former Ministry of Home Affairs official who served as deputy governor during the Great East Japan Earthquake, he pledged to achieve off-site final disposal of decontamination soil and implement measures to address population decline.
What were the results and voter turnout figures for the Niigata and Naha mayoral elections?
In Niigata, incumbent Nakahara Yaichi won his third term with 143,724 votes; turnout was 35.61%, up 3.51 percentage points from the previous election. In Naha, incumbent Chinen Satoru won his second term with 63,306 votes; turnout was 35.81%, down 11.24 percentage points from the previous election.
What records did Churanoumi set ahead of the Kyushu Grand Sumo Tournament?
Churanoumi became the first wrestler from Okinawa Prefecture ever to reach sumo's sanyaku ranks—a historic milestone. At 33 years and 5 months he is the fourth-oldest first-time sanyaku promotion in the post-war era, and his 63 basho from debut to promotion is the latest on record for any wrestler with a college sumo background.
What weather hazard should Hokkaido residents particularly watch for later this week?
A powerful cold air mass bringing midwinter-level cold—strong enough to produce snowfall even on Hokkaido's flat plains—will arrive Wednesday night, and residents should watch for accumulating snow through Thursday. Sapporo may see its first snowfall of the season, and Tokyo is also expected to experience its first cold seasonal winds (kogarashi).
Heavy Rain Warning as Former Typhoon No. 30 Lingers
Typhoon No. 30 transitioned into an extratropical cyclone in the East China Sea at 9 p.m. on October 25, but the danger is far from over. Warm, moist air continues to stream toward the cyclone and its associated frontal system, keeping rain clouds draped across wide areas of western and eastern Japan.
Rainfall has been especially heavy in Kyushu. In the 48 hours through 5 a.m. on October 26, Goto City in Nagasaki Prefecture recorded 302 millimeters—the highest 48-hour October total since records began.
The front is expected to remain active. Shikoku and the Izu Islands face the risk of extremely heavy rain exceeding 50 millimeters per hour. Forecast 24-hour precipitation totals through tomorrow morning stand at 200mm for Shikoku, 150mm for the Izu Islands, 120mm for the Kinki region, and 100mm each for the Kanto-Koshin, Tokai, and northern Kyushu areas. Northern Kyushu also faces sustained winds of up to 20 m/s and maximum gusts of 30 m/s. The Japan Meteorological Agency is urging vigilance against landslides and calling for caution regarding flooding of low-lying land, rising river levels, lightning, and tornadoes.
Fukushima Gubernatorial Election: Uchihori Masao Wins Fourth Term
In the Fukushima gubernatorial election, voted on and counted October 25, incumbent Uchihori Masao (内堀雅雄, 62) captured over 90% of valid votes, defeating six challengers by a landslide to win his fourth consecutive term.
Born in Nagano City, Uchihori joined the former Ministry of Home Affairs before being seconded to Fukushima Prefecture in 2001. When the Great East Japan Earthquake struck, he was serving as deputy governor and led the prefecture's emergency response. He first won the governorship in 2014. His campaign highlighted his recovery record and included pledges to press the national government and Tokyo Electric Power Company for off-site final disposal of decontamination soil and steady progress on decommissioning, while also prioritizing support for displaced residents and measures to address population decline.
Niigata Mayor and Naha Mayor: Incumbents Both Prevail
In the Niigata mayoral election, incumbent Nakahara Yaichi (中原八一, 67) secured 143,724 votes, defeating two challengers by a wide margin to win his third term. A native of Niigata City, Nakahara previously served in the Niigata Prefectural Assembly and the House of Councillors before winning his first mayoral race eight years ago. He campaigned on revitalizing the city center and generating activity through a large-scale arena project, as well as the early restoration of roads damaged by the Noto Peninsula earthquake. Voter turnout was 35.61%, up 3.51 percentage points from the previous election.
In the Naha mayoral election, incumbent Chinen Satoru (知念覚, 63) won his second term with 63,306 votes. He drew backing from a broad coalition spanning the Liberal Democratic Party, Nippon Ishin no Kai, the Democratic Party for the People, Komeito, and the Constitutional Democratic Party, campaigning on countering rising prices and strengthening child-rearing and education policies. Voter turnout was 35.81%, a drop of 11.24 percentage points from the previous election.
Kyushu Grand Sumo Tournament: Churanoumi Makes History for Okinawa
The rankings for the Grand Sumo Kyushu Basho—which opens at the Fukuoka International Center on November 8—have been announced. Churanoumi (チュラノ海, 33) of Kise Stable has been promoted to East Komusubi, becoming a first-time sanyaku wrestler. In the previous basho he went 10–5 as the No. 3 maegashira and received the Fighting Spirit prize.
At 33 years and 5 months, Churanoumi is the fourth-oldest first-time sanyaku promotion in the post-war era. His 63 basho from debut to promotion is also the latest for any wrestler who came up through college sumo. Most significantly, he is the first wrestler from Okinawa Prefecture ever to reach sanyaku—a historic first for the island.
Yoshinofuji (吉野富士) of Kumamoto Prefecture, who recovered from an 0–5 start in the previous basho to finish 9–6, returns to sanyaku at West Komusubi after a two-basho absence. Three wrestlers earn top-division debuts: Dewanoryu (出羽の龍), a Mongolian from Dewanoumi Stable; Ariisofuji (荒磯富士) of Fukuoka Prefecture from Isenoumi Stable; and Gokumiyu (極海遊), a Mongolian from Oshima Stable. The 41-year-old Tamawashi (玉鷲) returns to the top division for the first time in three basho, making him the oldest returnee since the Showa era.
Weather Outlook: Midwinter Cold Expected Later This Week
According to weather forecaster Ito Miyuki (伊藤美由紀), this morning's temperatures range from 1.5°C in Oumu, Hokkaido to –2.8°C in Shimukappu, while Kagoshima sits at a summery 26.9°C. Tokyo's forecast high of 18°C is 10 degrees lower than yesterday. Highs elsewhere: Naha 28°C, Kagoshima 29°C, Fukuoka 22°C, Osaka 21°C, Nagoya 19°C, and Sapporo 14°C.
The extratropical cyclone is expected to cross Kyushu during the day and reach south of Shikoku tonight, while a separate low-pressure system is forming near the Izu Islands. Heavy rain will continue to center on Shikoku and the Izu Islands through tomorrow.
Later in the week the pressure pattern will shift. Upper-level temperatures begin falling over western Japan from tomorrow night. By Wednesday night, a powerful cold air mass will push into eastern and northern Japan, bringing midwinter-level cold capable of producing snowfall even on Hokkaido's flat plains. Residents should be alert to accumulating snow through Thursday; Sapporo could see its first snowfall of the season. Tokyo is also forecast to experience its first kogarashi—the cold, blustering winds that signal the onset of winter—so a sharp seasonal change calls for preparation.
