Let's learn how to count in Japanese. Every language has a different way of counting objects; the Japanese use counters. They are similar to English expressions such as "a cup of ~", "a sheet of ~" and so on. There are a variety of counters, often based on the shape of the object. Counters are attached directly to a number (e.g. ni-hai, san-mai). Following the next couple of paragraphs, we have included counters for the following categories: objects, duration, animals, frequency, order, people and others.

Things which are not clearly categorized or shapeless are counted by using native Japanese numbers (hitotsu, futatsu, mittsu etc.).

When using a counter, pay attention to the word order. It is different from English order. A typical order is "noun + particle + quantity—verbs." Here are examples.

  • Hon o ni-satsu kaimashita.
    I bought two books.
  • Koohii o ni-hai kudasai.
    Please give me two cups of coffee.Another thing we want to mention is that when the Japanese group objects they divide them into groups of five and ten, unlike the typical groupings of six and twelve in the West. For example, sets of Japanese dishes or bowls are sold in units of five. Traditionally, there was no word for a dozen, though it has been used because of Western influence.
