AI 产品解读Bypass radiko.jp geolocation restrictions to listen to Japanese radio from any region or overseas
radiko.jp restricts radio streaming to specific Japanese regions based on IP geolocation. Users outside their registered area (or overseas) cannot listen to stations from other regions. Rajiko solves this by using the Android authentication flow with spoofed GPS coordinates instead of IP-based location checks, allowing access to all Japanese radio stations.
User installs extension and optionally selects a Japanese region in the popup. When visiting radiko.jp, the extension automatically intercepts auth requests and injects spoofed GPS coordinates for the selected area, bypassing geo-restrictions. User can then play any station. For recording, user clicks the record button in the popup during live playback. For timeshift downloads, user navigates to a timeshift program page and clicks the download button.

- 目标用户
- Japanese radio listeners outside their registered region in Japan / Overseas Japanese radio fans who want to access radiko.jp / Users who want to record or download radiko radio content
- The source code is available and well-documented with a detailed README, making analysis reliable. No server-side code needed verification. The only area of mild uncertainty is whether the timefree30 feature (which requires radiko premium login on the website) could be considered a paid feature of the extension—but since it requires radiko.jp's own premium subscription and the extension merely passes through the existing session cookie, it is properly classified as a destination_service feature, not an extension paid feature.
付费分析未识别到付费功能
The extension itself is completely free and open-source (GitHub: github.com/jackyzy823/rajiko). There is no payment UI, no subscription mechanism, no Stripe or other payment platform integration, and no features gated behind payment. The 'premium' references in the code (modules/auth.js line 8: 'Auth token generated with premium radiko_session cookie can access the tf30 resource') refer to radiko.jp's own premium subscription plan for timefree30 content—a destination service feature, not an extension feature. The Ko-fi link in the popup (pages/popup.html line 70) is a voluntary donation link for the developer, not a payment requirement for extension features. The 'subscribe' and 'premium plan' keywords detected in the heuristic are from the store description mentioning Ko-fi sponsorship and radiko's premium plan, neither of which constitute paid features within the extension itself.

- The extension's core functionality—bypassing radiko.jp geolocation restrictions to listen to live radio and download basic timeshift content—requires NO login. The extension programmatically generates random device info and auth tokens via radiko's Android auth API (auth1/auth2) without any user account (modules/auth.js lines 35-60). All 'auth' and 'token' references in the code are about radiko's API authentication flow, not user login. There is no login form, no account creation, and no sign-in UI in the extension. The only login-related mention is an optional case: to download 'timefree30' content (a radiko premium-only feature), the user must be logged into their own radiko.jp account via the website—but this is logging into the destination service, not the extension itself, and it is optional for a specific advanced feature.
感谢互联网,感谢开源
海外から聞いているのですが、再生しても途中で止まってしまうことが増えました、、、
海外から利用していますが昨夜から急に時間がマイナスの目盛からの出発となり、一時停止などができずリロードを要求され、その先が聞けなくなります。 Firefox 149.0でも同様です。 ご対応いただけると幸いです。 先日直ったと投稿しましたが、また元の状態に戻りました。 対応可能でしたら、よろしくお願いいたします。
おかげさまでWBCが聞けます!!!
想要聽7日內的廣播並下載,但不停顯示再生失敗,請求幫助 >__<
NHK以外は、録音できています。 感謝です。
アップデートありがとうございます!! 私は日本のラジオ番組がとても好きで、気に入った回を何度も繰り返し聴いて、日本語のリスニング練習をしています。 いつも継続的にメンテナンスやアップデートをしてくださって、本当にありがとうございます。感謝しています!
1/19辺りでは正常に機能していたタイムシフトダウンロードが本日1/26には使用できなかった。一瞬、赤い背景に1の文字が書かれたアイコンが右下に表示されるが動作せずに終わっている模様。
(2026/01/27) The download portion of the extension is back to normal. Developer, thank you very much for your prompt action. (2026/01/26) The download portion of the extension seems to be not working anymore.
昨日(1月14日)のChromeUpdateで再生できなくなりました。他のファイアーフォックスでは問題なく再生可能。 追記 2026年1月17日現在。修正されたことで正常動作を確認いたしました。有難うございます。
