〜ごとし / ごとく / ごとき: Likeness | Japanese Grammar

Modern Japanese says "X is like Y" with 〜のようだ or the casual 〜みたいだ. Both have a classical ancestor: ごとし（如し）, the auxiliary of resemblance meaning "like, as, as follows." It is one of the core signatures of the 漢文訓読 register — 如 is a standard kanbun gloss — and unlike most classical forms, it never really left. It survives in two places at once: in the neutral, slightly stiff comparison of formal writing and proverbs (光陰矢の如し, 以下のごとく), and in a sharp, evaluative second life where 〜ごとき means "the likes of." One classical word, two live modern uses — and the only thing telling them apart is the inflection and the context. This page teaches you to read both on sight.

Three living inflections

ごとし conjugates like an い-adjective (ク活用), so it has an adverbial form, an attributive form, and a sentence-final form. All three are alive in modern Japanese.

Form	連用形	連体形	終止形
Inflection	ごとく	ごとき	ごとし
Job	before a verb: "like / as"	before a noun: "a … like"	ends a sentence: "is like"
Modern echo	〜のように	〜のような	〜のようだ

It attaches to a noun ＋の／が or directly to a 連体形（attributive verb form）. When it follows a plain noun, you usually see の (矢の如し); when it follows an inflected verb, you usually see が (及ばざるが如し). That が is doing the linking job that modern の or に would do — a small but reliable tell of the classical register.

光陰矢の如し。

kōin ya no gotoshi

Time flies like an arrow. (光陰 'time' + noun 矢 'arrow' + の + 終止形如し — the single most quoted ごとし proverb)

過ぎたるは猶及ばざるが如し。

sugitaru wa nao oyobazaru ga gotoshi

Going too far is as bad as falling short. (論語; the 連体形及ばざる takes が before 如し, not の)

The literary comparison: 〜のごとく / 〜のごとし

In its neutral use, ごとく／ごとし is simply an elevated "like / as." It carries a written, formal ring — you meet it in essays, reports, editorials, eulogies, and 四字熟語. A famous cluster comes from the 風林火山 banner (itself drawn from 孫子）:

疾きこと風の如く、動かざること山の如し。

hayaki koto kaze no gotoku, ugokazaru koto yama no gotoshi

As swift as the wind, as immovable as a mountain. (風林火山; 連用如く mid-sentence, 終止如し at the end — and note 動かざる, classical negation, feeding straight into 如し)

彼女は疾風の如く現れて、去っていった。

kanojo wa shippū no gotoku arawarete, satte itta

She appeared like a gust of wind and was gone. (連用如く modifying the verb 現れる — the literary equivalent of 疾風のように)

Its most practical modern home is document boilerplate, where ごとく means "as [stated]." This is not archaic at all — it is standard in formal reports and correspondence:

以下のごとくご報告いたします。

ika no gotoku go-hōkoku itashimasu

I report as follows. (以下のごとく = 'as below' — routine formal-document phrasing; の links the noun 以下 to 如く)

周知のごとく、事態は深刻である。

shūchi no gotoku, jitai wa shinkoku de aru

As is well known, the situation is grave. (周知のごとく opens editorials and academic prose; compare 上記のごとく 'as above', 下記のごとし 'as follows')

💡

Read 〜のごとく／〜のごとし as nothing more exotic than "like / as / as follows." 周知のごとく is just 周知のように in a stiff collar. The formality is in the register, not the meaning — decode it plainly and business Japanese stops looking cryptic.

The second life: 〜ごとき, "the likes of"

Here is the twist that makes ごとし worth its own page. The 連体形 ごとき developed a purely evaluative use: "someone/something as (lowly / trivial) as." It ranges from humble self-deprecation to open contempt, and it is very much alive in speech and fiction.

Used of oneself, 私ごとき is self-lowering — "someone as unworthy as me":

私ごときがお引き受けして、本当に恐縮です。

watashi gotoki ga o-hikiuke shite, hontō ni kyōshuku desu

For someone as undeserving as me to take this on — I'm truly humbled. (私ごとき = self-deprecating 'the likes of me'; formal-humble register)

Used of someone else, お前ごとき is dismissive or scornful — "a nobody like you":

お前ごときに負けるわけがない。

omae gotoki ni makeru wake ga nai

There's no way I'd lose to the likes of you. (お前ごとき = contemptuous 'someone as beneath me as you' — stock fighting-talk in fiction and anime)

子供ごときに何がわかる、と彼は鼻で笑った。

kodomo gotoki ni nani ga wakaru, to kare wa hana de waratta

'What could a mere kid understand,' he scoffed. (子供ごとき = belittling 'a mere child')

The evaluative ごとき can also attach to an action to dismiss it as trivial — "a little thing like [merely]…":

試験に落ちたごときで、いちいち落ち込むな。

shiken ni ochita gotoki de, ichiichi ochikomu na

Don't get down over something as small as failing one exam. (ごとき after a 連体形 verb = 'a trifle like merely doing X')

💡

Same word, two readings. If ごとく／ごとし links a neutral comparison（矢の如し, 周知のごとく）, it means plain "like / as." If ごとき sits after a person or a trivial-sounding action（お前ごとき, 子供ごとき, 落ちたごとき）, it is evaluative — self-lowering or contemptuous. The inflection ごとき plus a human/trivial referent is the switch.

Why one word carries both

There is no contradiction between "like" and "the likes of" — the second grew straight out of the first. "A person like you" is a neutral comparison; but framed as "merely a person on the level of you," the same comparison becomes a ranking, and a ranking against a low bar is an insult. English does exactly this with "the likes of you" and "a mere child." So you never memorize two words. You recognize ごとし as "like," and let the inflection and the referent tell you whether it is drawing a picture or drawing a line.

Common mistakes

❌ 空は青いのごとし。

sora wa aoi no gotoshi

Wrong — attaching ごとし to an い-adjective with の. ごとし wants a noun (＋の／が) or a 連体形, not an adjective plus の.

✅ 空は青く澄んで、洗ったガラスの如し。

sora wa aoku sunde, aratta garasu no gotoshi

The sky is blue and clear, like washed glass. (ごとし attaches to the noun ガラス via の)

ごとし compares things to a noun (or the content of a 連体形 clause). You cannot bolt it onto an adjective the way you can さ or そう.

❌ 及ばざるの如し。

oyobazaru no gotoshi

Slightly off — after an inflected 連体形 like 及ばざる, the linker is normally が, not の.

✅ 及ばざるが如し。

oyobazaru ga gotoshi

…is as if it does not reach. (a 連体形 verb takes が before 如し — 過ぎたるは猶及ばざるが如し)

Nouns take の (矢の如し); inflected verb forms take が (及ばざるが如し). Using の after a 連体形 is not disastrous, but が is the idiomatic classical choice and the one the fixed proverbs preserve.

❌ 先輩ごときに教わって助かりました。

senpai gotoki ni osowatte tasukarimashita

Rude by accident — 〜ごとき of another person is contemptuous, so calling your 先輩 '先輩ごとき' insults them.

✅ 先輩に教わって助かりました。

senpai ni osowatte tasukarimashita

It helped me to be taught by my senior. (drop ごとき entirely; of others it belittles — reserve 〜ごとき-of-a-person for self-lowering 私ごとき or deliberate scorn)

This is the dangerous one. 〜ごとき aimed at another person is dismissive. Turn it on someone you respect and you have insulted them; use 私ごとき of yourself and it is polite humility.

❌ 以下のごとき、契約を締結する。

ika no gotoki, keiyaku o teiketsu suru

Wrong inflection — before a pause/verb you need the 連用形ごとく, not the 連体形ごとき.

✅ 以下のごとく、契約を締結する。

ika no gotoku, keiyaku o teiketsu suru

We conclude the contract as follows. (連用形ごとく does the adverbial 'as' work; ごとき is only for modifying a following noun)

Match the inflection to the slot: ごとく before a verb or a pause, ごとき before a noun, ごとし to close the sentence.

Key takeaways

ごとし（如し）= "like / as / as follows," the classical ancestor of modern 〜のようだ／みたいだ and a core kanbun signature.
Three living inflections: 連用ごとく（before a verb: 疾きこと風の如く）, 連体ごとき（before a noun）, 終止ごとし（sentence-final: 光陰矢の如し）.
It attaches to noun ＋の（矢の如し）or 連体形＋が（及ばざるが如し）.
Neutral use = literary comparison and document boilerplate: 周知のごとく, 以下のごとく報告いたします, 上記のごとく.
Evaluative 〜ごとき = "the likes of": humble of oneself（私ごときが恐縮です）, contemptuous of others（お前ごとき）— never call someone you respect 〜ごとき.
