NERV Disaster Prevention

- Added Earthquake Early Warning Real-Time Update Notifications (Live Activities) to Early Access - Added shortcuts to the Strong-Motion Monitor layer - Updated the Privacy Policy ◆ Earthquake Early Warning Real-Time Update Notifications When an Earthquake Early Warning (Forecast or Warning) is issued, a Live Activity will now display the Estimated Seismic Intensity at your current location, along with a Countdown Timer showing the number of seconds until strong shaking is expected to arrive. This information is updated in real time on your Lock Screen, in Notification Centre, on the Dynamic Island, and elsewhere. Previously, you had to unlock your device and open the app to see the Earthquake Early Warning countdown. With this update, you can now check that information directly from the Lock Screen. Real-Time Update Notifications are initially being offered as an “Early Access” benefit for Supporters’ Club members. Early Access lets members try newly developed features before everyone else, with those features later being made available to all users for free. We will announce the timing of the general release once it's been decided. ◆ Strong-Motion Monitor Layer Shortcuts We’ve added two new shortcuts for quickly opening the Strong-Motion Monitor layer: a widget that can be placed on the Lock Screen, and a control that can be added to Control Centre or assigned to the Action button. When assigned to the Action button, simply press and hold the button to open the Strong-Motion Monitor layer. ◆ About Early Access “Early Access” is a benefit for paid NERV Disaster Prevention Supporters’ Club members that lets them use new features before everyone else. For details, see the Supporters’ Club membership information in the app’s Menu tab. ◆ About the Supporters’ Club The Supporters’ Club is a fan club-style membership program supported by monthly membership fees from users who care about the NERV Disaster Prevention App. Membership benefits include Early Access to new features, Incoming Rain Alerts, permission to post to CRISIS Mapping, an increased number of registered locations, and, on higher-tier plans, access to members-only content. For details, see the Supporters’ Club membership information in the app’s Menu tab. ◆ Delivering Information Even One Second Faster The year 2026 marks 15 years since the Great East Japan Earthquake and 10 years since the 2016 Kumamoto Earthquake. Then, on July 28, an earthquake with a magnitude of 7.1 and a maximum Seismic Intensity of 7 struck the Kumamoto region of Kumamoto Prefecture, which the Japan Meteorological Agency named the “2026 Kumamoto Earthquake.” By the end of August, Earthquake Early Warnings (warning level) had already been issued more than 20 times. To deliver information even one second faster, we’ve spent years strengthening our information delivery infrastructure and improving the speed of the app. With this update, we’ve been able to implement Real-Time Update Notifications using features provided by the operating system, allowing us to deliver critical information even more quickly than before. We hope that being able to see this information directly on the Lock Screen will help you take action to protect yourself even one second sooner. Gehirn will continue working to further strengthen the delivery of disaster prevention information.

- Fixed an issue where "Emergency" wouldn’t display correctly in the timeline information on the "Weather Warnings/Advisories" detail screen - Other bug fixes We would like to express our deepest condolences to those who lost their lives in the 2026 Kumamoto Earthquake and the disasters caused by the heavy rain that began on August 13. Our thoughts are with all those who were affected, and we sincerely hope that their lives and well-being can recover as soon as possible. ◆ Developer Update In July, alongside developing new features for the push notification engine, the development team also worked on improving the stability and performance of the app and its systems. Through repeated testing, measurement, and analysis of various implementations, we were able to make significant improvements in these areas. In the process, we also identified a bug in the language runtime and implemented a workaround, gaining a number of valuable insights along the way. We deployed these improvements to production on July 27. Then, shortly after reporting the results to the team on the 28th, the 2026 Kumamoto Earthquake struck at 16:27. All we could do was watch and hope as the new version of the system handled a massive surge in notification traffic. Notifications were sent without any issues, but as we learned about the scale of the damage on the ground, the continued seismic activity, and then the heavy rain that followed from August 13, our hearts ached as we thought about the suffering and grief of all those who were affected. We truly hope that everyone whose lives were affected can return to a sense of normalcy as soon as possible.

- Additional fixes related to the new disaster weather information system - Fixed an issue where typhoons would sometimes not render in the “National” home screen tab - Updated the Privacy Policy We would like to apologise for the concern caused by the development team update in our previous release notes. We received many messages of support and concern from users and other organisations, and were even contacted by members of the National Diet and the Japan Meteorological Agency asking if there was anything they could do to help. Though we can’t go into too much detail out of consideration for our relationships with other organisations, we have maintained regular communication with the Japan Meteorological Agency throughout both the lead-up to and rollout of the new disaster weather information system. More recently, we also visited the JMA headquarters for an in-person meeting to exchange views and share information, and have submitted requests for further improvements. Now that the work surrounding the new disaster weather information system has settled down, the development team has once again started work on new features! We’re excited to get them to you as soon as possible, so please bear with us for a little longer. Thank you for always supporting the NERV Disaster Prevention app.

* Added support for the new disaster weather information system The development team has been working around the clock for weeks to implement this major overhaul of our disaster weather warnings and advisories systems. We deeply sympathise with the Japan Meteorological Agency and the many disaster prevention organisations that are also working through large-scale system changes. Because these changes affect long-standing operational and technical infrastructure, many organisations across the country are facing significant adaptation costs, including system upgrades and revisions to operational procedures. Even just before launch, the Japan Meteorological Agency continues to revise municipal support tables and sample messages, leaving little time for integration testing or trial operations before the system goes live. As a result, there may be unforeseen issues during the initial rollout. Please be mindful that there may still be bugs or issues in the NERV Disaster Prevention app while we work through this transition. During this year’s flood season, we encourage everyone to avoid relying solely on disaster weather information and to use their own judgment to stay safe above all else. Please also take care in the heat.
