📖 Grammar Notes ▼

Sino-Japanese numbers — いち、に、さん…

These numbers come from Chinese and are used with most counters and for larger quantities:
  • 1〜10: いち、に、さん、し(よん)、ご、ろく、しち(なな)、はち、きゅう(く)、じゅう
  • Decades: にじゅう (20)、さんじゅう (30)、よんじゅう (40)、ごじゅう (50)…
  • ひゃく (100) — note: し (4) and しち (7) are avoided in many contexts as they sound like death (死) and loss (失); use よん and なな instead.

じゅう＋ [1–9] ＝ [11–19]

juu + [1–9] = [11–19]

→ じゅういち (11), じゅうに (12), じゅうさん (13)…

にじゅうきゅうさいです。

Nijuu kyuu sai desu.

I am 29 years old.

Native Japanese counters — ひとつ、ふたつ、みっつ…

These count general objects (not people, animals, or thin/long things). Use them in shops when ordering quantities:
ひとつ (1)、ふたつ (2)、みっつ (3)、よっつ (4)、いつつ (5)
むっつ (6)、ななつ (7)、やっつ (8)、ここのつ (9)、とお (10)
After 10, switch back to Sino-Japanese. These can be used without a noun ("I'll have three") and feel natural in daily shopping and counting.

みっつおねがいします。

Mittsu onegaishimasu.

Three please. (e.g. three apples, three items)

～えんです — stating a price

Prices in Japanese always end with えん (yen), followed by です. The number always uses Sino-Japanese:
• ひゃくえん (¥100)、にひゃくえん (¥200)、さんびゃくえん (¥300)
• Note the sound change: さんびゃく (300), ろっぴゃく (600), はっぴゃく (800) — the ひ changes for smooth pronunciation.

[PRICE] えんです。

[price] en desu.

→ "It's [100] yen." — just number + えん + です.

さんびゃくえんです。

San byaku en desu.

It's 300 yen.

～さいです — stating your age

さい (歳) is the counter for years of age. Always use Sino-Japanese numbers (not native counters) with さい:
  • にさい (2), じゅっさい (10), はたち (20 — special form), さんじゅうさい (30)
  • To ask politely: おいくつですか？ (lit. how many, honourable?) — very soft and polite.
  • Standard: なんさいですか？— normal, fine in most contexts.
  • Casual: なんさい？— fine among friends.

にじゅうさんさいです。

Nijuu san sai desu.

I am 23 years old.

～ずつ — "each / apiece"

ずつ attaches to a number (usually native counter) to mean "that many each":
  • ひとつずつ — one each
  • みっつずつ — three each
  • すこしずつ — little by little (すこし = a little)
It is often combined with a verb of distribution: わける (to divide), あげる (to give), くばる (to hand out).

ふたつずつくばってください。

Futatsu zutsu kubatte kudasai.

Please hand out two each.
