AI product readBypass 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.

- Target users
- 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.
MonetizationNo paid features detected
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.

- Reason
- 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.

表示がいきなり隣の県になってしまいめっちゃ困っていましたがこれインストールして解決できました。 今の所は使えています。
Не один год работало отлично, а теперь, после обновления, сломалось. Почините, пожалуйста! upd 24.9.3 Тогда починили, и работает. Надеюсь, сделают так, чтобы расширение не удалили из гугл-плей, о чем предупреждает сайт. Оно мне очень нужно! Приложение, останься, пожалуйста!
I love this extension and I've been using it for years already, however, it's not working as of the moment. Really hope it gets fixed 😭
Radikoへ課金をしていましたがとても使いにくい。このご時世に課金しても海外でも聞くことができません。VPNを使えばどうにでもなるというのに… もはやこのプラグインがなければ仕事ができません。 いつもアップデートをしていただき本当にありがとうございます。
海外出張のたびに世話になっていた本機能ですが、久しぶりに海外からアクセスしようたら、海外から接続NGと弾かれてしまいました。海外での活力を得る手段の一つだったため残念です…
It wasn't working for some days, now it's perfect again. Thanks! I hope something like this appears for Android. It's not possible to listen Radiko overseas in my smartphone.
今日は使えないのでしょうか? VPNを開かないと使えない。
