Japanese Counter Words: Hitotsu, Futatsu (1 to 10)

For everyone learning Japanese, do you find the counting system really complex? Even simple terms like "one thing" or "two things" have special pronunciations rather than the standard "ichi, ni, san." This is a major hurdle every beginner must face—native Japanese counter words (the ~tsu system). To help everyone breeze through this challenge, our school has launched a brand-new interactive learning game! This time, our super cute mascot, GeGe, takes center stage to join you in counting seeds in a bowl. Through visuals, clear pronunciation prompts, and hands-on practice, you'll naturally master the pronunciations from 1つ to 10 in no time!

In Japanese, when counting 3D objects that lack specific counter suffixes (such as apples, oranges, or mystery gifts) or abstract concepts (such as an idea or a reason), we use this ancient "~tsu system" (native Japanese counters). This counting method is a guaranteed topic on the JLPT N5 exam and one of the most essential grammar points for daily life—like when ordering at a restaurant: "I'd like one Set C, please."

To ask 'how many' or 'how many items' in Japanese, the most common question word is 'いくつ (Ikutsu)'. When asking about the quantity of objects, you can use 'いくつ' directly—for example, 'りんごはいくつありますか。' (Ringo wa ikutsu arimasu ka?, meaning 'How many apples are there?'). 'いくつ' is primarily used for counting general items without specific counter suffixes. In everyday speech, adding the honorific prefix to say 'おいくつですか' (O-ikutsu desu ka?) is also a polite way to ask someone's age. It is an essential and practical Japanese question word.

Drag the English numbers to the matching Japanese numbers

After learning native Japanese numbers (wago) from 1 to 10, you might wonder: How do you say 11 or 12 in Japanese? The good news is that after 10, everything reverts to standard "Number + 個 (ko)"! In modern Japanese, the ancient ~tsu system is typically only used up to 10. From 11 onward, we simply use Sino-Japanese numbers (the standard ichi, ni, san system) combined with a counter word (usually the generic counter 個 / ko). This is because ancient native Japanese counting pronunciations become extremely complex and difficult to memorize as numbers get larger. To make communication more efficient, modern Japanese standardized on the Chinese-based number system for anything past 10.

• For example：
  • 11 items： じゅういっこ (Juuikko) [11 + ko]
  • 12 items： じゅうにこ (Juuniko) [12 + ko]
  • 20 items： にじゅっこ (Nijukko) or にじゅーこ (Nijuuko)

Pro Tip: Notice that "10" is written without a "つ". Its pronunciation is the long vowel sound "tō" (To-o)—be careful not to mispronounce it as "tootsu"!
