What this episode answers
Where is Typhoon No. 26 approaching and what damage is expected?
Typhoon No. 26 is expected to approach the Izu Islands from this evening through October 1, with waves of up to 5 meters in the southern islands and 24-hour rainfall of 150mm forecast; Chiba Prefecture, where ground is already unstable from Typhoon No. 25 last week, could also face warning-level heavy rain depending on the typhoon's path, raising the risk of landslides and flooding even with relatively light rainfall.
What was the background behind Lawson's nationwide flood-barrier rollout, and how effective have the barriers proven to be?
After last month's record heavy rains flooded more than 10 convenience stores — mainly in Chiba Prefecture — and forced temporary closures, Lawson decided to expand flood barriers to high-risk stores nationwide; a Chiba store that sustained about 50 cm of flooding last month used the barriers to almost completely block water at its entrance during Typhoon No. 25, with headquarters covering all installation costs going forward.
What stance did President Trump take on AI regulation and China policy?
President Trump said he 'didn't talk much' about AI with President Xi at their summit 'because I didn't want to do anything,' signaling reluctance toward AI regulation, while stressing he wants to maintain a competitive advantage over China; he also signed an executive order to use AI to streamline federal government procedures.
How is the arson attack on an Estonian defense company said to be linked to Russia?
Estonia's security chief stated he is 'convinced Russia was behind' the arson at Milrem Robotics in Tallinn, saying Russian intelligence services are targeting defense firms involved in supporting Ukraine — a company that has been confirmed to supply unmanned vehicles to Ukraine; Russia's Kremlin denied the allegations, calling them baseless.
How did Nadeshiko Japan win their Asian Games semifinal match?
Nadeshiko Japan defeated South Korea 2-0, with Kamiya (神谷) of Sanfrecce Hiroshima Regina heading home a long pass 9 minutes into the second half for her fifth consecutive goal of the tournament, then intercepting an opponent's back-pass 18 minutes into the second half and finishing with her left foot for the second goal.
Typhoon No. 26 Approaches Izu Islands Tonight; Chiba Faces Heavy Rain Threat Again
Typhoon No. 26 is expected to approach the Izu Islands from the evening of September 30 through October 1. Violent winds are forecast for the southern islands, with waves of 5 meters in the south and 3 meters in the north and off Chiba Prefecture. Twenty-four-hour rainfall totals are projected at 150mm in the southern islands and 60mm in the north, with very heavy rain possible in the south from tonight through tomorrow. Hachijojima recorded 31mm of rain in the single hour up to 5 a.m.
Meteorological authorities have warned that Chiba and Kanagawa prefectures — which sustained record rainfall damage from Typhoon No. 25 last week — could again see warning-level heavy rain depending on the typhoon's path and speed. Officials noted that already-unstable ground and damaged embankments mean even lighter rainfall than usual could trigger landslides and flooding. Residents are urged to complete preparations and move to safe locations while it is still light, before heavy rain arrives overnight. The number of consecutive rainy days recorded in central Tokyo has broken the longest such streak since observations began in the city. Gusts and tornadoes are also a concern.
Lawson to Roll Out Flood Barriers at High-Risk Stores Nationwide
Following repeated flooding of stores during heavy rain, convenience store chain Lawson has decided to expand installation of flood barriers to at-risk stores across Japan. During last month's record rainfall around August 14, more than 10 convenience stores — mainly in Chiba Prefecture — were flooded and forced to temporarily close.
Lawson has already installed flood barriers at around 80 stores nationwide. At one Chiba store that had approximately 50 cm of water inside during last month's downpours, the barriers almost completely blocked water from entering through the entrance when Typhoon No. 25 hit this month. Store manager Nishida (西田) said: "I had my doubts at first, but the barrier almost completely prevented flooding at the entrance. It really helps because it shortens the time before we can reopen." Going forward, Lawson will solicit interest from owners of high-risk stores, with headquarters covering all installation costs and rolling out the barriers progressively.
Trump Signals Reluctance on AI Regulation, Emphasizes Competition with China
At a Washington event on September 29, U.S. President Trump commented on his summit with President Xi Jinping, saying he "didn't talk much" about AI "because I didn't want to do anything," signaling reluctance toward AI regulation. He added, "If we cooperate with China, they'll learn many secrets. I want to maintain an advantage over many countries, including China," reaffirming his competitive posture.
The White House has already announced the establishment of a dialogue framework to discuss AI risks and benefits as a summit outcome. At the same event, Trump also signed an executive order to create a government website using AI to streamline federal procedures, promoting the acceleration of domestic AI adoption.
Arson at Estonian Defense Firm Attributed to Russian Sabotage
In mid-August, a building belonging to defense company Milrem Robotics in the Estonian capital Tallinn was set on fire, and local security services arrested three Latvian nationals. On September 29, Estonia's security chief publicly stated: "We are convinced Russia was behind it. Russian intelligence services are targeting defense companies involved in supporting Ukraine." The company has been confirmed to be supplying unmanned vehicles to Ukraine.
Vigilance against Russian sabotage and cyberattacks is rising across Europe; Denmark's intelligence agency stated in a report published on September 24 that such incidents will "increase further." Kremlin spokesman Peskov denied any Russian involvement, saying the allegations "lack reasonable grounds and we do not intend to take them seriously."
Sports: Nadeshiko Japan Advance to Asian Games Final
In the women's football semifinal at the Asian Games on the night of September 29, Nadeshiko Japan (なでしこジャパン, world-ranked 5th) defeated South Korea (world-ranked 19th) 2-0 to advance to the final. After a goalless first half, Kamiya (神谷) of Sanfrecce Hiroshima Regina (サンフレッチェ広島レジーナ) headed home a long pass 9 minutes into the second half to open the scoring — her fifth consecutive goal since the opening match of the tournament. Kamiya struck again 18 minutes into the second half, intercepting an opponent's back-pass and finishing with her left foot. Nadeshiko Japan will face North Korea (world-ranked 11th) in the final on October 2, aiming for a third consecutive Asian Games title.
