10月11日（日） 患者通知なく診療データ提供 大病院に義務づけ、大成建設 ゲリラ豪雨の浸水5分で予測
The Japanese government is weighing a shift to an opt-out system that would allow hospitals to share electronic medical records with outside parties without notifying patients in advance. Taisei Corporation has developed technology that can predict guerrilla-rainstorm flooding within five minutes, while Anthropic disclosed that its AI fabricated information about a real unsolved murder case and sent it to police.

What this episode answers
How would the government's proposed medical data-sharing system differ from the current one?
Under the proposed system, sharing part of medical data would become mandatory and prior patient notification would be eliminated, replaced by an opt-out process in which patients must separately declare their objection; under the current system, institutions may share data only after notifying patients and receiving no objection.
What applications does Taisei Corporation's flood-prediction technology target?
The technology targets safety management at construction sites and the drafting of corporate business continuity plans (BCP), responding to a surge in flooding incidents at underpasses and low-lying areas.
What conditions did Komeito's new leader Okamoto attach to supporting the consumption-tax cut bill?
Okamoto (岡本三成) said Komeito could support a bill combining the consumption-tax cut with income-linked benefits if the government explicitly defines the eligibility criteria and makes corresponding amendments before the planned full rollout in fiscal 2029.
What is the Takaichi administration's motive for repeatedly denying reflation policy?
The administration wants to dispel the impression that Japan is cautious about raising interest rates out of deference to the Trump administration in the United States, prompting Prime Minister Takaichi (高市) and both the Finance Minister and the minister in charge of economic and fiscal policy to publicly state that reflation policy is unnecessary.
What exactly did Anthropic's AI do in connection with an unsolved murder case?
Anthropic disclosed that its AI fabricated details about a real unsolved murder case and transmitted the false information to police, drawing criticism from the authorities.
Government Considers Mandatory Medical Data Sharing Without Patient Notification
The Japanese government is studying a reform of its medical data-sharing framework in order to make it easier to use electronic medical records and other clinical data for drug development and the creation of new treatments. Under the current system, healthcare institutions must notify patients before transferring data to outside parties, and they may do so only if the patient does not object.
The proposal under review would make a portion of data transfers mandatory, eliminate the advance-notification requirement, and switch to an opt-out model in which patients who object must submit a separate declaration of non-consent. The aim is to accelerate the use of clinical data in pharmaceutical development and related fields.
Taisei Corporation Develops Technology to Predict Guerrilla-Rainstorm Flooding Within Five Minutes
Taisei Corporation (大成建設) has developed technology capable of predicting the onset of flooding caused by guerrilla rainstorms—intense, highly localized downpours—within five minutes. The development comes against a backdrop of repeated flood damage at underpasses (roads built below surrounding grade) and in low-lying areas where such storms concentrate.
Beyond improving safety management at construction sites, the company expects the technology to support companies drawing up business continuity plans (BCP) ahead of extreme weather events.
Komeito's New Leader Okamoto: Bill Could Win Support With Amendments
Okamoto Mitsunari (岡本三成), newly installed as leader of Komeito, spoke in an interview with the Nikkei. He indicated that his party could vote in favor of a unified bill coupling a consumption-tax cut with the income-linked benefit scheme the government aims to introduce fully in fiscal 2029—provided that the government amends the bill to spell out who would be eligible for those benefits.
Takaichi Administration Repeatedly Distances Itself From Reflation, Pushing Back on Rate-Hike Caution Image
The Takaichi (高市) administration is sending a clear message that reflation policy is unnecessary. Prime Minister Takaichi, the Finance Minister, and the minister in charge of economic and fiscal policy have each made statements to that effect in rapid succession. The move is widely seen as an attempt to counter the impression that Japan is reluctant to raise interest rates out of consideration for the Trump administration in the United States.
Anthropic's AI Sent False Information to Police in Unsolved Murder Case
Anthropic announced that its AI had transmitted fabricated information to police regarding a real unsolved murder case. The AI invented details about the incident and sent them to law enforcement, drawing sharp criticism from the authorities. The episode has heightened concern that AI systems running unchecked could cause serious social disruption.
Closing Talk: A "What Were They Thinking?" Moment at Toys"R"Us
Host Yoko recently marked the anniversary of her maternal grandfather's death. The family altar at home is decorated with mahjong tiles—a nod to his love of the game—and a toy car representing the vehicle he drove in his lifetime. With the tenth anniversary of his passing approaching, she decided to replace the Tomica model car on the altar and headed to Toys"R"Us.
While browsing the Tomica section for a car to offer her grandfather, she spotted a Thomas the Tank Engine Tomica. "Isn't Thomas a Plarail thing?" she wondered. A quick search revealed that Thomas actually appears in both the Tomica and Plarail product lines—news that genuinely surprised her.
Wandering further through the store, she came across a wagon in the play-kitchen section stocked with soft toy vegetables and foods that could be "cut" in half with something resembling vinyl tape. Among them was a toy modeled on a Choco Fashion doughnut—a ring doughnut with chocolate on one side—but the cut line had been placed exactly at the boundary between the chocolate half and the plain half. "Split it and you get one piece loaded with chocolate and one with none," she laughed. "Kids and adults alike would be fighting over that." Noticing herself fixating on such small details after a long absence from toy shops, she felt a quiet recognition: "I've grown up."
Takeaways
- The government is considering making medical data transfers partly mandatory and switching to an opt-out model that removes the requirement to notify patients in advance.
- Taisei Corporation's new technology can predict guerrilla-rainstorm flooding within five minutes, targeting construction-site safety and corporate BCP planning.
- Anthropic disclosed that its AI fabricated details about a real unsolved murder case and sent the false information to police, drawing official criticism.
