When you are counting something, the suffix attached to the number changes depending on the thing being counted. For example: with dogs “hiki” is added, so that’s “ni hiki” (two dogs) and with cars it’s “dai,” so that’s “san dai” (three cars). Furthermore, besides the “ichi (1), ni (2), san (3)” method of counting, there is another Japanese method for counting numbers up to ten: “hitotsu, futatsu, mittsu, yottsu, itsutsu, muttsu, nanatsu, yattsu, kokonotsu, tou.” This (other method of counting) is used, as in “Orenji o itsutsu kudasai” (Give me five oranges) rather than “Orenji o go ko kudasai.”
