English builds ordinals with an irregular little kit — "first, second, third," then a tidy "-th" for the rest. Japanese has no dedicated ordinal words at all. Instead it attaches an ordinal marker to a perfectly ordinary number, and there are three of them: the everyday 〜番目 (ばんめ), the formal prefix 第〜 (だい), and — the real workhorse — the suffix 〜目 (め), which clips onto any counter and turns it ordinal. Once you see how 〜目 works, "the third day," "the second time," and "the fifth glass of beer" all fall out of one systematic pattern.
〜番目: the everyday ordinal
For ordinary "first, second, third" — position in a line, in a ranking, in a sequence of things — you use 番目. It's built from 番 (ばん, the counter for numbered positions) plus the ordinalizing 目:
| Ordinal | Reading | Meaning |
|---|---|---|
| 一番目 | いちばんめ (ichiban-me) | the first |
| 二番目 | にばんめ (niban-me) | the second |
| 三番目 | さんばんめ (sanban-me) | the third |
| 四番目 | よんばんめ (yonban-me) | the fourth |
| 何番目 | なんばんめ (nanban-me) | which (in order)? |
前から二番目の席が私のです。
mae kara niban-me no seki ga watashi no desu
The second seat from the front is mine.
三番目の信号を右に曲がってください。
sanban-me no shingō o migi ni magatte kudasai
Please turn right at the third traffic light.
Note the pattern [ordinal] + の + [noun]: 二番目の席 ("the second seat"), 三番目の角 ("the third corner"). The ordinal attaches to the noun with の, just like any modifier.
日本で二番目に高い山は何ですか。
nihon de niban-me ni takai yama wa nan desu ka
What is the second-tallest mountain in Japan?
That last one shows a very common frame: 番目に + adjective = "the Nth most ~." 二番目に高い = "the second highest." You'll reach for it constantly ("the third biggest," "the fifth most popular").
一番 vs 一番目: the trap
Here is the error that trips up nearly every learner. 一番 (いちばん) ichiban on its own does not mean "first" in the sense of order — it means "number one / the most / best," a superlative marker. To say "the first (in a sequence)," you need 一番目 ichiban-me, with the 目.
このクラスで彼が一番背が高い。
kono kurasu de kare ga ichiban se ga takai
He is the tallest in this class.
Here 一番 = "the most" (一番背が高い = "tallest"). Compare:
列の一番目の人がチケットを見せた。
retsu no ichiban-me no hito ga chiketto o miseta
The first person in the line showed their ticket.
一番目の人 = "the first person (in order)." Drop the 目 and 一番の人 would drift toward "the number-one / best person" — a different meaning. When you mean position, keep the 目.
For the two ends of a sequence, Japanese also has the ready-made nouns 最初 (さいしょ, "the first / the beginning") and 最後 (さいご, "the last / the end"), which often sound more natural than 一番目 / 最後の一つ:
最初はうまくいかなかったけど、だんだん慣れてきた。
saisho wa umaku ikanakatta kedo, dandan narete kita
At first it didn't go well, but I gradually got used to it.
第〜: the formal prefix
第 (だい) goes in front of a number and belongs to formal, technical, and written contexts — chapters, articles, editions, ranks, historical events. Where 番目 is spoken and everyday, 第 is the register of textbooks, contracts, and headlines.
今日は第一課から勉強しましょう。
kyō wa dai-ikka kara benkyō shimashō
Today let's study from Lesson 1.
第一課 = dai-ikka — note the sound change: 一 geminates before 課 (か), giving いっか. 第 combines freely with counters: 第一巻 (だいいっかん, Volume 1), 第三章 (だいさんしょう, Chapter 3), 第二位 (だいにい, second place), 第三者 (だいさんしゃ, "a third party / outsider").
第二次世界大戦は一九四五年に終わった。
dai-ni-ji sekai taisen wa sen-kyū-hyaku-yon-jū-go-nen ni owatta
The Second World War ended in 1945.
彼女はマラソンで第一位に輝いた。
kanojo wa marason de dai-ichi-i ni kagayaita
She took first place (shone in first) in the marathon.
〜目: the productive ordinalizer
This is the part most textbooks scatter across a dozen lessons without ever naming the pattern — so here it is stated plainly: the suffix 〜目 (め) attaches to almost any [number + counter] and makes it ordinal. Take a normal counted phrase and add 目, and "three days" becomes "the third day," "two times" becomes "the second time."
| Cardinal (count) |
| Meaning |
|---|---|---|
| 三日 (mikka) three days | 三日目 (mikka-me) | the third day |
| 二回 (ni-kai) two times | 二回目 (ni-kai-me) | the second time |
| 三人 (san-nin) three people | 三人目 (san-nin-me) | the third person |
| 五杯 (go-hai) five cups | 五杯目 (go-hai-me) | the fifth glass/cup |
| 二年 (ni-nen) two years | 二年目 (ni-nen-me) | the second year |
| 一行 (ichi-gyō) one line | 一行目 (ichi-gyō-me) | the first line |
日本語の勉強を始めて、今年で三年目です。
nihongo no benkyō o hajimete, kotoshi de san-nen-me desu
This year is my third year since I started studying Japanese.
同じ映画を見るのはこれで三回目だ。
onaji eiga o miru no wa kore de san-kai-me da
This is the third time I've watched the same movie.
The 〜目 pattern is what makes ordinals systematic. You don't memorize a separate ordinal for "the fifth glass of beer" — you take the count 五杯 and add 目:
彼はもう五杯目のビールを頼んでいる。
kare wa mō go-hai-me no bīru o tanonde iru
He's already ordering his fifth beer.
うちの三人目の子どもが来月生まれます。
uchi no san-nin-me no kodomo ga raigetsu umaremasu
Our third child is due next month.
Watch the sound changes carry through: 一回目 is ikkai-me (一 geminates before 回), 一冊目 is issatsu-me, 一日目 is ichinichi-me. The ordinal 目 doesn't change anything — the number-plus-counter behaves exactly as it does when counting, then 目 rides along on the end. See the 回 counter and the floating quantifier rules for where these phrases sit in a sentence.
番 without 目: just a label number
One more distinction. 番 by itself (no 目) means "number N" as a label, not a rank — a jersey number, a house number, a "now serving" ticket. 三番 = "number three" (the thing labeled 3); 三番目 = "the third one (in order)."
三番の窓口へどうぞ。
san-ban no madoguchi e dōzo
Please go to counter number three.
三番の窓口 is the window labeled 3; it isn't necessarily the third window you'd walk past. Add 目 and 三番目の窓口 becomes "the third window (counting along)." Small difference, real consequences.
Common mistakes
❌ 一番の人がチケットを見せた。(meaning 'the first person in line')
Incorrect — 一番 means 'the best/number-one person,' not 'first in order.'
✅ 一番目の人がチケットを見せた。
ichiban-me no hito ga chiketto o miseta
The first person (in order) showed their ticket.
一番 is the superlative "the most." For position, you need the 目: 一番目. Or use 最初の人.
❌ 三回、同じ映画を見た。(intending 'this is my third time watching it')
Incorrect — 三回 is a plain count ('three times'), not the ordinal 'the third time.'
✅ これで三回目だ。
kore de san-kai-me da
This is the third time. — the 目 makes it ordinal.
三回 answers "how many times" (three). To say "the third time," add 目: 三回目.
❌ 二目の席 (for 'the second seat')
Incorrect — 目 must attach to a counter (番, 人, 回…), not a bare number.
✅ 二番目の席
niban-me no seki
the second seat — number + counter (番) + 目.
You can't bolt 目 straight onto a bare number. It needs a counter to ride on: 二番目, 二人目, 二回目.
❌ 第一目の課 (for 'Lesson 1')
Incorrect — 第 and 目 are two different ordinal systems; don't stack them.
✅ 第一課
dai-ikka
Lesson 1 — the formal prefix 第 alone.
第 (prefix) and 目 (suffix) are alternative strategies, not partners. Use one: 第一課 (formal) or 一課目 (colloquial "the first lesson"), never both.
Key takeaways
- Japanese has no standalone ordinal words; it marks ordinals with attachments.
- 〜番目 is the everyday "first, second, third" for position (二番目の席), and 番目に + adjective = "the Nth most ~."
- 一番 ≠ first. 一番 = "the most/best" (superlative); 一番目 = "first in order." The 目 is decisive. For sequence ends, 最初 / 最後 are natural.
- 第〜 is the (formal) prefix for chapters, ranks, and set terms: 第一課, 第二次, 第一印象.
- 〜目 is the productive engine: [number] + [counter] + 目 ordinalizes anything you can count — 三日目, 二回目, 五杯目, 三人目.
