To change the language in League of Legends, the easiest and official way is through the Riot Client:
- Open the Riot Client and make sure you are logged out.
- Click on your profile icon at the top right corner.
- Select "Settings."
- In the settings menu, find and select "League of Legends."
- Under "Game Text Language," choose your desired language from the dropdown list.
- Close the settings and click the update button that appears to download the new language files.
- Restart the client, and the game will be in your chosen language.
If this method doesn't work or you want more language options, you can manually change the language code in the game configuration file "LeagueClientSettings.yaml" found in the League of Legends installation folder. After editing the locale code (e.g., ja_JP for Japanese, en_US for US English), save the file and launch the game using a shortcut with the added parameter --locale=your_language_code. These changes affect client text, voice lines, and in-game notifications without impacting gameplay or matchmaking. This method is reversible and can be done anytime via the client settings or file editing. For complete step-by-step instructions with language codes and alternative methods, several guides and videos are available online for 2025 updates.
