๐Ÿ”ข Nouns, Numbers and Counters โ€” ใ‚ใ„ใ—ใƒปใ‹ใšใƒปใ˜ใ‚‡ใ™ใ†ใ—

Chapter 1 told you that Japanese nouns have no plural. This chapter shows what Japanese does instead: it counts, and it counts with a small word attached to the number, called a counter. You will learn the numbers up to 10,000, the all-purpose counter ใ€œใค, five everyday counters, and then use the same machinery for money, clock times and dates.

The rule in one box A noun never changes for number. To say how many, put number + counter after the noun and its particle, before the verb: ใ‚Šใ‚“ใ”ใ‚’ ใฟใฃใค ใ‹ใ„ใพใ™ (I buy three apples). The counter depends on the kind of thing counted (people, flat things, long things, machines), and the number and counter often change sound when they meet.

1. No plural, but group endings for people

A bare noun can be singular or plural: hon is "a book", "the book" or "books". Only for people and (sometimes) animals there are group endings:

EndingUseExampleSay it
ใ€œใŸใกa group of people, the usual pluralkodomo-tachi (children)
ใ€œใŸใก with a pronounwe, you (plural)watashi-tachi, anata-tachi
ใ€œใ‚‰slightly rougher or written; theykare-ra (they, mostly male or mixed)
Repeating the noun"many, various" (a few words only)hitobito, yamayama (people; mountains)
Watch out: ใŸใก is not used for things or for "a lot" ใ€œใŸใก goes on people (ใ›ใ‚“ใ›ใ„ใŸใก, teachers). Never put it on ใปใ‚“ or ใใ‚‹ใพ. And when the number is stated, you do not need it: ใŒใใ›ใ„ใŒ ใ•ใ‚“ใซใ‚“ ใ„ใพใ™ (There are three students), not ใŒใใ›ใ„ใŸใกใŒ ใ•ใ‚“ใซใ‚“.

Four, seven and nine each have two readings. ใ‚ˆใ‚“, ใชใช, ใใ‚…ใ† are the safest everywhere; ใ—, ใ—ใก, ใ survive in set expressions (ใ—ใŒใค April, ใ—ใกใ˜ seven o'clock, ใใ˜ nine o'clock).

3. Numbers 11 to 10,000

From 11 the numbers are built like a sum: tens, then units. Nothing to memorise beyond 1-10 and the place words.

NumberJapaneseSay itHow it is built
11jลซichi10 + 1
20nijลซ2 ร— 10
34sanjลซyon3 ร— 10 + 4
99kyลซjลซkyลซ9 ร— 10 + 9
100hyaku
1,000sen
10,000ichimanone ten-thousand: ใ„ใก is required before ใพใ‚“

Hundreds and thousands change their sound in three places. Learn these exceptions and the rest are regular:

NumberHundreds (็™พ)Thousands (ๅƒ)
1 hyaku (100) sen (1,000)
2 nihyaku nisen
3 sanbyaku (b) sanzen (z)
4 yonhyaku yonsen
5 gohyaku gosen
6 roppyaku (pp) rokusen
7 nanahyaku nanasen
8 happyaku (pp) hassen (ss)
9 kyลซhyaku kyลซsen
Say big numbers in 10,000s Japanese counts in units of ไธ‡ (man, 10,000), not thousands: 30,000 is (3 ร— 10,000) and 100,000 is (10 ร— 10,000). Prices and populations all follow this, so it is worth practising early.

4. The general counter ใ€œใค

For ordinary objects when you do not know a special counter, use the native series ใฒใจใค, ใตใŸใค โ€ฆ It counts up to ten; from 11 you use plain numbers (ใ˜ใ‚…ใ†ใ„ใก) with no counter.

5. Five everyday counters

A counter is a suffix that tells what kind of thing is counted. Five cover most of daily life:

CounterForExamples
ใ€œไบบ -nin (people)peoplestudents, friends, customers
ใ€œๆžš -maiflat, thin thingspaper, tickets, shirts, plates, CDs
ใ€œๆœฌ -hon / -pon / -bonlong, thin thingspens, bottles, trees, umbrellas, rolls (of film)
ใ€œๅ€‹ -kosmall, roundish thingsapples, eggs, sweets, boxes

One and two people are irregular (ใฒใจใ‚Š, ใตใŸใ‚Š), and four is ใ‚ˆใซใ‚“ (not ใ‚ˆใ‚“ใซใ‚“). From three on it is number + ใซใ‚“.

Flat things, long things, small things, machines

Where the sounds change ใ€œๆžš and ใ€œๅฐ are completely regular. ใ€œๆœฌ and ใ€œๅ€‹ change after 1, 6, 8 and 10 (ใ„ใฃใฝใ‚“, ใ‚ใฃใฝใ‚“, ใฏใฃใฝใ‚“, ใ˜ใ‚…ใฃใฝใ‚“) and ใ€œๆœฌ also after 3 (ใ•ใ‚“ใผใ‚“) and in ใชใ‚“ใผใ‚“. The rule behind it is the one from Chapter 2: the small ใฃ and the voiced / half-voiced marks (ใปใ‚“ โ†’ ใผใ‚“, ใฝใ‚“).

Counters in a sentence

PatternExampleEnglish
noun + particle + quantity + verb
ringo o mittsu kudasai
Three apples, please.
noun + ใŒ + quantity + ใ„ใพใ™ / ใ‚ใ‚Šใพใ™
gakusei ga sannin imasu
There are three students.
question
pen wa nanbon arimasu ka
How many pens are there?

Notice there is no particle after the quantity (ใฟใฃใค stands alone), and the counted noun still carries its own particle (ใ‚’, ใŒ, ใฏ).

Other counters you will meet ใ€œๅ†Š -satsu (books), ใ€œๅŒน -hiki (small animals), ใ€œๆฏ -hai (cups, glasses), ใ€œๅ›ž -kai (times), ใ€œๆญณ -sai (age). If you do not know the counter, ใ€œใค usually works for objects.
