Additionally, we have tried to make a group multiple times and the members of the group are unable to access the group after it have been established. I’ve tried creating another group many times and it simply won’t work. Please update and fix these bugs ### 1/5 — Deleting app *2026-07-02* Glitchy app - stalls out a lot. Worse is that it raises the alarm when nothing is happening. Deleting app. **Developer response:** We're sorry Japan Alerts let you down, and we take the false alarms especially seriously on a safety app. Both problems have been fixed. The alerts firing when nothing was happening came from a server-side issue that could re-trigger earthquakes which had already passed. We found and fixed it, and that fix is already live for everyone, with no update needed. The stalling and glitches were fixed in version 2.0.3, now available. If you're willing to give it another try, we'd love the chance to earn back your trust. Either way, thank you for the honest feedback. Please stay safe. Japan Alerts team ### 1/5 — 話にならない *2026-07-02* 実際に地震が来て通知は来たが開こうとしても一切開けない。何度も消して開いてを繰り返してやっと開けても何も表示されない。 **Developer response:** この度はご不便をおかけし、誠に申し訳ございませんでした。実際の地震の際に通知を開けなかったとのこと、いざという時にお役に立てず、心よりお詫び申し上げます。 ご報告いただいた「通知を開いても表示されない／開けない」不具合は、バージョン2.0.3で修正し、すでに配信を開始しております。お手数をおかけしますが、最新版にアップデートのうえ改めてお試しいただけますと幸いです。 貴重なご報告に重ねて御礼申し上げます。今後も安心してお使いいただけるよう改善を続けてまいります。どうぞ安全にお過ごしください。 Japan Alerts 開発チーム ### 5/5 — Great app for non-Japanese speakers living or traveling in Japan *2026-04-21* This app allows to get alerts issued by official agencies in various languages in timely manner. There is also a function that allows to create a group so that you can check if all the members of the group are fine in case of the emergency. If your family member is going to Japan, or living in Japan, it will be a very useful tool. **Developer response:** Thanks for your review. Version 2.0 is a way better. Hope you will like it. ### 2/5 — Constant stress!!! *2026-04-21* This app kept alarming every 2 minutes telling me to evacuate because there was a tsunami warning + earthquake, however I was waaaay too far away. I had to turn off my phone as I didn’t wanted to delete the app, in the end I did as everywhere I went in public it was screaming and stressing everyone out… make it location based… you can’t tell people to evacuate when we didn’t even feel the quake. **Developer response:** Sorry for that ! We made the settings easier to set in the version 2.0 ## Frequently asked questions about Japan Alerts ### Does Japan Alerts have ads? Yes, Japan Alerts contains advertisements.

The family group is the heart of Japan Alerts: the people you want to reach first when something happens, and the ones who want to know you are safe. This version makes that connection effortless from start to finish. Creating a group takes moments. Joining is the same simple step whether you tap the button or open a link someone sent you, and the app tells you exactly where you stand at every point. Your group stays with you: through a weak signal, through closing the app and coming back, and onto a new phone, where your place in the family is waiting for you. The people who matter most, ready before you need them. Thank you for using Japan Alerts. Stay safe. ### 2.1 — 2026-07-30 The same watchful app, now steadier when it matters most. When a major earthquake strikes, everyone opens the app in the same moment. We reworked how alerts and the alert list are delivered so they stay fast and dependable during exactly that surge, when you most need to see what is happening and where. We also made the nearby-shelter map load more quickly and more reliably, so the places that can keep you safe are ready the instant you open it. The rest of this version is quieter work: improvements to stability and clarity across the app. The app you rely on, ready for the moments that matter most. Thank you for using Japan Alerts. Stay safe. ### 2.0.7 — 2026-07-20 Same watchful app, now with more accurate alerts. You can now set your place by simply choosing your prefecture, with no GPS and no map. It is the fastest way to receive the alerts that genuinely concern you, and it asks for no location sharing at all. The rest of this version is devoted to edge cases, those rare situations where an alert could go astray: a distant tremor with no felt effect treated as an emergency, a ward of a major city labelled with the name of its prefecture, an evacuation order attached to the wrong place, a safety check-in request arriving with no alert to explain it. These situations are now handled correctly. We also revised several screens so they stay clear when you have given only a prefecture. Set your places once. We handle the rest. Thank you for using Japan Alerts. Stay safe. ### 2.0.6 — 2026-07-16 Same watchful app, now lighter and faster. Live alerts stay in sync while using far less background battery and data, with quicker and more dependable delivery across the app. We also refined a few small interface details to make everyday use clearer. Set your places once. We handle the rest. Thank you for using Japan Alerts. Stay safe. ### 2.0.5 — 2026-07-13 A small update, made with care. Japan Alerts is now leaner and more dependable. IMPROVED - Lower background data usage - Privacy and security improvements - Stability and reliability improvements throughout Thank you for using Japan Alerts. Stay safe, and tell us what to build next. ## More apps by Itchigoo - [The Poker Calculator](https://appshunter.io/ios/app/the-poker-calculator/id372170915) - [Checkers game](https://appshunter.io/ios/app/checkers-game/id404242044) - [Black and white board games](https://appshunter.io/ios/app/black-and-white-board-games/id1501315302) All apps by Itchigoo: https://appshunter.io/developer/372170918 ## Related topics [japan earthquake alert](https://appshunter.io/ios/topics/japan-earthquake-alert) · [safety tips japan](https://appshunter.io/ios/topics/safety-tips-japan) · [jnto safety tips](https://appshunter.io/ios/topics/jnto-safety-tips) · [itchigoo](https://appshunter.io/ios/topics/itchigoo) · [地震 日本](https://appshunter.io/ios/topics/地震-日本) · [minami disaster prevention](https://appshunter.io/ios/topics/minami-disaster-prevention) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
