Japanese numbers up to 100 are shown below. Note that numbers four, seven and
nine (underlined) have alternating forms: yon, yo and shi for four, nana and
shichi for seven and kyū and ku for nine. The form depends on what is counted,
such as 4 o’clock or yo-ji and four minutes or yon-pun. Japanese numbers are
usually followed by a classifier, which indicates what is counted or numbered.
Use of “bare” numbers (counting the number of push-ups, etc.) is rather limited.
