Among the agreements: China will import at least 10 million tons of US coal annually in both 2027 and 2028. The two sides also announced the establishment of a framework for dialogue on AI. ## Lower House Electoral Reform: "Effort Toward a Concrete Conclusion" on Seat Reductions The contents of a draft agreement from the ruling-opposition council on Lower House electoral system reform came to light on September 26. On reducing the number of Lower House seats, the draft states that lawmakers will "strive to reach a concrete conclusion," tied to a review of the current single-member-district/proportional-representation system. A conclusion on reforming the current system is targeted by the end of October. ## OpenAI's AI Accessed SEC and IRS Websites It emerged on September 25 that an AI OpenAI has in development had previously accessed the websites of the US Securities and Exchange Commission (SEC) and the US Internal Revenue Service (IRS). OpenAI explained that these are sites the general public can access, and that no unauthorized intrusion or data leak occurred. ## Microsoft Adds Document Creation and Co-Editing to Copilot Microsoft announced on September 25 that it is bringing core word-processing and spreadsheet functions into its AI app Copilot. The update will also allow co-editing with colleagues, meaning users will be able to complete document creation entirely within Copilot. ## NTT Docomo to Raise Mobile Rates for the First Time in December In December, NTT Docomo will raise rates on its existing mobile plans for the first time. The move puts an end to a price-cutting competition among carriers, reflecting cost increases from inflation and other factors in its pricing. While the company expects some improvement in earnings, the axis of competition in the industry is shifting toward service quality, putting renewed focus on improving communication quality. ## "Lonely Chaplin" Comes to the Rescue The host admitted to being uncomfortable singing in front of others, saying karaoke outings are reserved for close friends and family. Recently, though, at a gathering of acquaintances, the mood turned to "everyone sings one song." What saved the host in this bind was advice from their mother, once a salesperson at a financial company. She had told them, "Once you're working, you'll have chances to go to karaoke with people older than you, so make sure you can sing at least this one song" — the song being "Lonely Chaplin" by Masayuki Suzuki with Rats & Star. In the moment, the host asked an older man nearby, "Would you sing this with me?" and got through it as a duet. The host, who left the salaried workforce after just one year, said they never had the chance to go to karaoke with a boss, and laughed that "I never imagined my mother's lesson would pay off like this." They closed by asking listeners: "Do you have a go-to song you can always sing without fail?" ## Takeaways - China agreed at the US-China summit to import at least 10 million tons of US coal annually in 2027 and 2028. - A ruling-opposition council pledged to work toward a concrete conclusion on Lower House seat reductions, tied to electoral system reform, by the end of October. - NTT Docomo will raise mobile rates for the first time in December as industry competition shifts from price to service quality.
