3.1 版新功能 • 您各個地點周圍的震動：每次有感地震後，在地圖上查看氣象廳在您各個地點附近測得的震度。Premium。 • 火山灰會落在哪裡：噴發後，逐小時查看氣象廳的火山降灰預報，以及您各個地點的預計降灰量。Premium。 • 問題修正與改進。

3.0 版大幅增加了日本氣象廳的警報與資訊，並新增地圖，讓您看到它們所預告的內容。 • Premium 為您的每個地點提供新的警報：河川氾濫、線狀降雨帶、強風、大雪、龍捲風、中暑、火山噴發速報、降灰，以及高樓的長週期地震動。 • 當氣象廳針對南海海槽或北海道與三陸近海發布巨大地震臨時資訊時，Premium 也會通知您。「防災」頁面會說明應採取的行動，以及您的地點是否位於相關區域內。 • Premium 新增天氣地圖，顯示警報所預告的內容：降雨雷達、衛星雲圖、颱風預測路徑、雷雨、龍捲風與線狀降雨帶。 • 當雨即將抵達您家時，Premium 會在「警報」頁面頂端顯示一張卡片，告訴您預計開始下雨的時間。 • 所有使用者：遠離日本的地震現在也會顯示發生地點，所有時間皆依您手機的時區顯示。 感謝使用 Japan Alerts，請注意安全。

• 設定你關心的地點時，能更準確地辨識是否位於日本境外。如有此情況，App 會提示你，並引導你改設日本境內的地點。 • 已解除的警報會從列表中消失。氣象廳解除避難資訊或豪雨警報後，卡片會立即消失，不再滯留數日。 • 日文文案由母語者全面校訂，涵蓋警報標題、推播通知與安全提示。

避難警報現在依您所在的市區町村推送，3 級豪雨與洪水警報也不再遺漏。 動態只顯示您所在市區町村的避難警報，而不是整個都道府縣：東京市中心的住家只會看到真正相關的幾則警報，而不是數十則。自訂監視區域採用同樣的方式，各自對應所在的市區町村，推播通知也逐一區域判定：同一都道府縣內兩個門檻不同的區域，會完全依照您的設定運作。當您把「住家」改為新地址時，警報會立即跟隨新的市區町村。 3 級豪雨與洪水警報現在一律顯示在動態中，即使在警報最多的日子也不例外，且每則警報只標示真正涉及的區域。日文介面已由母語人士全面審閱，用詞更清楚，各畫面語氣一致。 感謝使用 Japan Alerts，請注意安全。

整個應用程式的說明更加清楚，涵蓋所有語言。 從警報畫面到「防災」分頁中的指南，Japan Alerts 現在會更準確地說明誰應該行動、如何行動：標示危險區域（陡坡、易淹水區域、低窪海岸），並說明警報來自日本氣象廳，避難指示則由當地政府發布。 所有畫面現在使用統一的用語，每個警戒等級在任何畫面、所有支援的語言中都表達相同的意思。地名現在也以繁體中文顯示。 感謝使用 Japan Alerts，請注意安全。

為了更好的使用體驗，本次更新包含一些技術與介面上的小幅改進。 Japan Alerts 現在啟動更流暢、更穩定，即使網路狀況不佳，也會直接開啟警報列表。 我們同時優化了部分介面細節，多個畫面現已在所有支援的語言中正確顯示。 感謝使用 Japan Alerts，請注意安全。

十二種語言，以及一張值得信任的地圖。 Japan Alerts 現已支援越南文與繁體中文。警報、地名與安全指引，共十二種語言。 火山這次是真的做全了。日本氣象廳能夠點名的每一座火山都已進入 App，警報依你與那座山的實際距離送達，而不再只看它位於哪個都道府縣。 地圖先前悄悄地是錯的，現在不再如此。海上的震央畫在海上。發生在地圖邊界之外的事件，會顯示一個指向它的箭頭，而不是一個假裝在別處的圓點。 你或許還會注意到：同一次地震的完整報告抵達後，先前的速報會讓位；家庭緊急模式現已涵蓋政令指定都市的居民；通知音效畫面在先前仍為英文的語言中已完成翻譯。 感謝你使用 Japan Alerts。願你平安。

Your family, one tap away. 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.

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.

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.

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.
