You can change the screen's colors, text size and display language yourself. All of these are done from the account menu at the top right of the screen (the button with your name or photo).

  1. Open the account menu at the top right of the screen.

  2. In Color mode (カラーモード), choose Light (ライト), Dark (ダーク) or System (端末設定). System follows the settings of your computer or smartphone.

  3. In Text size (文字サイズ), choose Standard (標準), Comfortable (大きめ) or Large (最大).

Color mode and text size settings are saved in the browser on the device you are using. On another device or browser, set them again.

  1. Choose Display language (表示言語) in the account menu. Basic information (基本情報) in your profile opens.

  2. In Display language (表示言語), choose Japanese, English, Chinese (Simplified), Korean or Vietnamese.

  3. Press Save changes (変更を保存).

The display language is also used for the student and guardian portals and for bulletins.
