Not an official summary. Heavy rain driven by a stationary autumn rain front set a September all-time record of 281 mm in 24 hours across Fukushima Prefecture on September 27, 2026, while Typhoon No. 26 is forecast to approach the Okinawa main island with an extremely strong intensity on the 28th. Separately, a memorial service was held in Otaki Village, Nagano Prefecture, marking 12 years since the deadly 2014 Mt. Ontake eruption, with the director-general of the Japan Meteorological Agency attending for the first time since 2015. ## What this episode answers ### How much rain fell in Fukuoka Prefecture in 24 hours, and what does that figure mean as a September record? AMeDAS points across Fukuoka Prefecture recorded 281 mm of rainfall in the 24 hours leading up to around 2:00 p.m. on September 27, the highest 24-hour September total since records began. ### Where is Typhoon No. 26 heading, and what hazards should people be on guard against? Typhoon No. 26 is forecast to approach the vicinity of Okinawa's main island on the 28th while retaining extremely strong intensity, and people are urged to guard against high waves, strong winds, and heavy rain, with conditions potentially worsening further. ### What sequence of events led to the Science Council of Japan transitioning to a special corporation? Six years ago, then-Prime Minister Suga Yoshihide refused to appoint six members recommended by the Science Council of Japan itself, and that dispute ultimately led to the decision to restructure the council as a special corporation, which will take effect next month. ### What did the director-general of the Japan Meteorological Agency say at the Mt. Ontake 12th-anniversary memorial service? Director-General Nomura said he believes the wish of those who lost their lives is for the JMA to make unceasing efforts to provide more reliable information to protect both climbers and nearby residents, and pledged that all staff will engage sincerely with volcanic disaster preparedness. ### What was the outcome of the lawsuit in which bereaved families sought damages from the national government and Nagano Prefecture? A ruling against the bereaved families became final in January of this year, meaning their claim that the failure to raise the volcanic alert level was unlawful was rejected. ## Article ## Record-Breaking September Rainfall in Northern Kyushu According to the Japan Meteorological Agency (JMA), a stationary autumn rain front caused developed rain clouds to stream continuously into northern Kyushu on September 27. AMeDAS observation points across Fukuoka Prefecture recorded 281 mm of rainfall in the 24 hours leading up to around 2:00 p.m. — the highest 24-hour September total since records began. By nightfall the rain had begun to ease across northern Kyushu, but because the heavy rain has already loosened the ground in many areas, authorities warn that the risk of landslides remains and continued vigilance is essential. ## Atmospheric Instability Nationwide on the 28th; Typhoon No. 26 Approaches Okinawa On September 28, the influence of frontal systems and moist air masses will make atmospheric conditions highly unstable across a wide swath of the country stretching from northern Japan through western Japan, raising the risk of locally heavy rain accompanied by thunder. In addition to landslides and flooding in low-lying areas, people are urged to guard against lightning strikes, tornadoes, and other violent gusts. Typhoon No. 26 is developing rapidly and is forecast to approach the vicinity of Okinawa's main island on the 28th while retaining an extremely strong intensity. JMA is calling on residents to be fully alert to high waves, strong winds, and heavy rain, noting that the storm's track could cause conditions to deteriorate further. ## Science Council of Japan Holds Symposium Ahead of Corporate Transition A group of researchers convened a symposium in Tokyo on September 27 ahead of the Science Council of Japan's (日本学術会議) transition from a government organ to a special corporation next month. The council has historically operated independently of the government, providing policy recommendations on scientific matters. The current debate over its organizational structure was triggered six years ago when then-Prime Minister Suga Yoshihide refused to appoint six members recommended by the council itself. That dispute ultimately led to the decision to restructure it as a special corporation. A former president of the council who spoke at the event stressed that "it is important to maintain a sense of mission as representatives of Japan's scientists and to offer scientific advice to the government — not to align with the government, but to fulfill the role of a scientific organization." Two of the six researchers whose appointments were rejected six years ago also participated: Matsumiya Takaaki (松宮孝明), a specially appointed professor at Ritsumeikan University, and Professor Okada of Waseda University. Matsumiya reiterated that "it was clearly illegal not to appoint the six members, and the fact that that situation has gone unresolved for six years is a serious problem." ## 12th Anniversary of Mt. Ontake Eruption; JMA Director-General Attends Memorial The eruption of Mt. Ontake (御嶽山) on September 27, 2014, claimed 58 lives with 5 people still missing — 63 casualties in total — making it the worst volcanic disaster in postwar Japan. On the 12th anniversary of the eruption, a memorial service hosted by local authorities was held in Otaki Village (王滝村), Nagano Prefecture, at the foot of the mountain. About 60 bereaved family members and local officials attended. At 11:52 a.m. — the exact moment the eruption occurred — those present observed a moment of silence facing the stone monument bearing the victims' names and the mountain itself. Bereaved families had filed a lawsuit against the national government and Nagano Prefecture, arguing that the failure to raise the volcanic alert level before the eruption was unlawful and seeking compensation, but in January of this year a ruling against the families became final. Following the conclusion of the litigation, JMA Director-General Nomura attended the memorial — the first director-general to do so since 2015. At the service, Nomura said: "I believe the wish of those who lost their lives is for the JMA to make unceasing efforts to provide more reliable information and thereby protect both those who climb the mountain and those who live nearby. All of our staff will carry this in our hearts and pledge to engage sincerely with volcanic disaster preparedness." After the ceremony, one bereaved family member who lost both a son and his fiancée said: "Bringing up what has ended won't bring them back, but observation equipment has improved, so I want the agency to issue information and absolutely stop people from going up whenever it seems dangerous." ## Takeaways - A stationary autumn rain front dumped a September all-time record of 281 mm in 24 hours on Fukuoka Prefecture, and atmospheric instability will persist nationwide on the 28th as Typhoon No. 26 bears down on Okinawa with extremely strong intensity. - The Science Council of Japan held a symposium ahead of its transition to a special corporation next month, with its former president and researchers denied appointments six years ago calling on the body to maintain its independence from the government. - The JMA director-general attended the 12th-anniversary Mt. Ontake memorial for the first time since 2015, pledging continued commitment to volcanic disaster preparedness, while a bereaved family member called for timely and decisive public warnings.
