How to test your Japanese keyboard
It takes about a minute. Use your physical keyboard: clicking the keys on screen doesn't test anything.
Press every key
Click the keyboard above, then press each key on your Japanese keyboard. Working keys light up and stay tinted, and the counter shows your progress.
Check the special keys
Press the IME toggle key and the Space bar used for conversion. Try Shift and Alt Gr combinations as well, since many characters need them.
Match your keyboard
Choose Windows or Mac, and ISO if your keyboard has an extra key next to the left Shift, so the keyboard on screen matches yours.
About the Japanese keyboard
Japanese is typed through an input method editor (IME). You type in romaji or kana and then convert the text to kanji. Japanese keyboards in the JIS layout have extra keys such as 半角/全角 and 変換, while a US keyboard works too once the Japanese IME is on.
The tester follows the physical key you press, so it shows whether the key itself works. The character that appears in a document depends on the layout selected in Windows or macOS. If the right key lights up but the wrong character appears, change your language setting. Our guide to the keyboard layout explains the standard rows and special keys.
Add the Japanese keyboard to Windows or Mac
Install the layout once, then switch to it whenever you type in Japanese.
On Windows
- Open Settings and go to Time & language, then Language & region.

- Add the Japanese keyboard layout.
- Switch between layouts with the Windows key + Space.
On a Mac

Fix common Japanese keyboard problems
Most problems come from a wrong layout setting or a stuck key, and both are quick to fix.
Wrong characters appear
The wrong layout is active. Switch with the Windows key + Space, or Control + Space on a Mac, and remove layouts you don't use. Learn how keyboard layouts work.
A key does nothing
If it stays dark in the tester, clean around it and try our fixes for stuck keys. A full keyboard reset fixes many software problems.
Everything types in capitals
Your Caps Lock key may be stuck on. Tap it once, then check it in the tester above.
The keyboard keeps disconnecting
Replace the batteries, move closer to the computer and pair your wireless keyboard again.
Frequently asked questions
How do I test my Japanese keyboard online?
Click the keyboard tester at the top of this page and press every key. Each working key lights up and stays tinted. Pay special attention to the IME toggle key and the Space bar used for conversion.
Why does my Japanese keyboard type the wrong characters?
Your computer is using a different layout from the one printed on your keys. If the tester lights up the key you pressed, the keyboard itself is fine. Add the Japanese layout in Windows or macOS and switch to it.
How do I switch between Japanese and English?
On Windows, press the Windows key + Space to move through your layouts. On a Mac, press Control + Space or pick the layout from the input menu in the menu bar.
