In Japanese, the QWERTY-based JIS keyboard layout is used, and the pronunciation of each character is entered using Hepburn romanization or Kunrei-shiki romanization. There are several kana-based typing methods.
The JIS standard layout includes Japanese kana in addition to a QWERTY style layout.
For entering Japanese, the most common method is entering text phonetically, as romanized (transliterated) kana, which are then converted to kanji as appropriate by an input method editor. It is also possible to type kana directly, as input to the conversion step.
The extra keys in the bottom row, and the changed keys in the leftmost column, control various aspects of the conversion process and select different modes of input.
