Japanese Keyboard Layout

A Japanese computer keyboard usually combines a QWERTY letter layout with Kana legends and Japanese input-control keys. The simplified JIS diagram below shows how both input systems can coexist on one physical keyboard.

What does a Japanese keyboard look like?

A typical Japanese JIS keyboard resembles a compact QWERTY keyboard, but many letter keys carry a second Kana legend. The space bar is shorter to make room for conversion controls. Key shapes and positions vary by manufacturer, so the diagram is explanatory rather than a hardware specification.

How does a Japanese keyboard work?

The keyboard sends keystrokes to a Japanese input method editor (IME). In Romaji mode, QWERTY sequences such as kyo become きょ. In Kana mode, a physical key maps directly to its printed Kana. The IME can then convert a phonetic reading into context-dependent Kanji candidates.

Common Japanese keyboard keys

KeyMeaningTypical role
半角/全角Half-width / full-widthOften toggles Japanese IME input
変換ConversionStarts or cycles Kana-to-Kanji conversion
無変換No conversionConfirms or changes conversion behavior
かなKanaSwitches or selects Japanese Kana input on some systems

Do you need a Japanese physical keyboard?

No. Most learners and many native users type Japanese with Romaji on standard QWERTY hardware. A JIS keyboard is useful when you want its dedicated conversion keys or direct Kana legends, but the operating system's IME matters more than the printed keycaps.

Frequently asked questions

Is the Japanese keyboard QWERTY?

Most Japanese computer keyboards use QWERTY for Latin letters. JIS models add Kana legends, Japanese input keys, and different punctuation positions.

What is an IME?

An input method editor interprets keystrokes and converts phonetic input into Japanese scripts and Kanji candidates. It is software, not the physical keyboard itself.

Can a US keyboard use Kana input?

Software can enable Japanese input, but direct Kana mapping is harder without printed Kana legends. Romaji input is usually the practical choice on US hardware.
