User reviews

Rajiko is a Chrome extension widely praised for allowing users, especially those outside Japan, to access Radiko radio stations and download programs. Users appreciate its region-switching feature and compatibility with multiple browsers. However, recent updates caused download functionality disruptions and playback errors. The impending deprecation of Manifest version 2 in Chrome also threatens its future usability. Users face more complicated workflows to bypass region restrictions. Despite these challenges, it remains a valued tool for enjoying Japanese radio content remotely.
Pros
  • Allows users outside Japan or restricted regions to listen to Radiko radio stations.
  • Provides download functionality for Radiko programs, especially useful for time-free listening.
  • Supports region change, enabling access to various prefecture radio stations across Japan.
  • Works on multiple browsers like Chrome, Firefox, and Brave.
  • Highly appreciated by users for enabling listening to favorite radio shows that would otherwise be inaccessible.
Cons
  • Recent updates removed or broke the download feature temporarily, causing inconvenience.
  • Manifest version 2 deprecation in Chrome threatens the extension's functionality and requires urgent updates.
  • Region restriction workaround has become more complicated; some users need to manually select prefectures to listen to out-of-area stations.
  • Some updates introduced errors such as failure to play streams and buttons not showing up properly.
  • Playback issues or recognition as foreign IP occurs during consecutive program playbacks.

I've been lived in Tokyo Japan for 3yrs. Since I leaved there, I can no longer listen Radiko anymore because of the region restriction as everyone knows. Really give my big thanks to Rajiko ext and the developer. Kudos.

ありがとうございます!大変助かります! 一つのお願いですが、現在"タイムフリー30プラン"を加入している場合、ダウンロード機能も7日間以内の番組しかダウンロードできません。今後のリリースには7日間超過の番組もダウンロード可能にすれば幸いです。
