This is a plain Japanese typing test. Pick 30 or 60 seconds, choose whether you want single station names or full announcement sentences, and start typing — the clock starts on your first keystroke, not on a button.
Romaji mode shows the romanised spelling and fills it in letter by letter, so it works with no Japanese knowledge at all. Kana mode is typed on the same keyboard with the same romaji, but the display fills in kana as each mora completes, which is how you learn to read what you are typing.
Every spelling the game accepts is accepted here: shi or si, tsu or tu, sha or sya. A wrong key is simply refused rather than inserted, so you never need to backspace to recover — though backspace works if you want it.
How the score is worked out
CPM is correct characters divided by elapsed minutes. WPM is that divided by five, the standard convention that treats five characters as one word — so a Japanese typing score here is comparable to an English one.
Accuracy is correct keystrokes over total keystrokes. Backspaces are not counted against you; rejected keys are. The same functions compute the numbers on this page, in the station-name game and on the leaderboards, so a WPM means the same thing everywhere on the site.
Nothing here is stored or submitted. This page keeps no history and posts no scores — it is a measuring stick, not a competition.
