# ともあろうものが: of all people (expression showing surprise at a high standing person's misbehavior) > Learn how to use ともあろうものが, a JLPT N1 Japanese grammar point meaning 'of all people' for expressing disbelief at someone's unexpected misbehavior, with structure, examples, nuance, and comparisons. JLPT level: N1 · Updated: 2026-05-18 · Canonical: https://hane-app.com/blog/n1-tomo-arou-mono-ga/ **ともあろうものが** means **of all people**. It is a **JLPT N1** Japanese grammar pattern used to express disbelief or shock when someone of high status, credibility, or responsibility acts in a way that contradicts their standing. This grammar point is emphatic and often judgmental — it highlights how unexpected and disappointing the behavior is, coming from that particular person. It appears in formal complaints, news commentary, and N1 reading sections. If you want to underline that a figure like a teacher, doctor, or official has done something beneath them, **ともあろうものが** is your tool. ## What does ともあろうものが mean? Use **ともあろうものが** when you want to express shock that a person of high standing — someone you expected better from — has done something wrong, embarrassing, or unbecoming. It frames the person’s status as the very reason the action is hard to believe. Natural translations: - of all people - a person like that, of all people - that someone in their position would… The translation shifts depending on how directly you want to challenge the person’s credibility. The core is always: *this person’s status makes the misbehavior shocking*. ## How to form ともあろうものが
Noun (person) ＋ ともあろう ＋ 者(もの) → ともあろうものが
The noun must refer to a person or role of high standing, trust, or authority. **もの** (person) can be left as **者(もの)**, but reading stays もの. The **が** is the subject particle, often followed by a verb phrase showing the surprising action. Common patterns: - 先生(せんせい)ともあろうものが - 警察官(けいさつかん)ともあろうものが - 議員(ぎいん)ともあろうものが In JLPT questions, the wrong option often uses a grammar point that attaches to verbs or adjectives — remember, ともあろうものが only attaches to a **noun** describing a person. ## When is ともあろうものが used? Use **ともあろうものが** in situations like: - reacting to a public figure’s scandal or mistake - expressing strong disappointment in a trusted professional - criticizing a leader or authority figure who failed expectations - formal editorials, news analyses, or serious conversations Tone and register: formal, critical, emotionally charged. It’s not for casual “that’s a bummer” remarks — it carries the weight of indignation. In writing, you’ll often see it in newspaper columns or opinion pieces. In speech, it sounds stern and judgmental, so use it carefully. ## ともあろうものが example sentences

disbelief
After reading each sentence, ask yourself: *What status does this person hold, and why does that make the action shocking?* That mental link cements the nuance better than a dictionary translation. ## Nuance of ともあろうものが The key nuance is **the person’s high standing magnifies the wrongdoing, turning a normal mistake into a betrayal of trust**. Think of it as the Japanese equivalent of the English “Of all people, *him*?!” — but heavier. Because the pattern literally says “even being the person who should be…” , it implies that the person has failed a fundamental duty tied to their role. The shock isn’t just about the action; it’s about the *gap between expectation and reality*. Compared to simply saying “驚い(おどろい)た” (I was surprised), ともあろうものが makes the criticism **personal** and **directed at the role**, not just the event. It’s often a rhetorical device to highlight moral failure. Use it when you want to underline hypocrisy, not just report an incident. ## ともあろうものが vs くせに Both **ともあろうものが** and **くせに** express a contrast between what is expected and what actually happens, but their focus and emotional tilt differ.
ともあろうものが
of all people; shock at a high‑status person’s misbehavior
vs
くせに
despite being; in spite of (criticism or contempt)
**ともあろうものが**: - The speaker is shocked, disappointed, or indignant. - Focuses on the person’s **title, standing, or the trust placed in them**. - Used in formal contexts and third‑person criticism (rarely about oneself). **くせに**: - The speaker is annoyed, sarcastic, or belittling. - Focuses on the person’s **trait or condition**, regardless of social standing. - Often informal; can be used about peers, even oneself when self‑deprecating. Quick contrast: - 先生(せんせい)ともあろうものが、遅刻(ちこく)するなんて。 (Shock: a teacher should never be late.) - 先生(せんせい)のくせに、遅刻(ちこく)するなんて。 (Annoyance: for a teacher, he’s pretty sloppy.) Even when both translate to “for a teacher,” the first sentence carries moral weight, the second sounds like an irritated remark. Check the speaker’s relationship to the subject: are they looking *up* in disappointment (ともあろうものが) or *down* with disrespect (くせに)? ## Common mistakes with ともあろうものが
❌
彼(かれ)はともあろうものが、約束(やくそく)を忘れ(わすれ)た。
✅
彼(かれ)はくせに、約束(やくそく)を忘れ(わすれ)た。
Use ともあろうものが only for people in authority, not a regular friend. くせに fits casual annoyance.
❌
病気(びょうき)ともあろうものが、仕事(しごと)を休ん(やすん)だ。
✅
病気(びょうき)にもかかわらず、仕事(しごと)を休ん(やすん)だ。
ともあろうものが requires a person noun, not a condition like illness. Use にもかかわらず for "despite".
❌
学生(がくせい)ともあろうものが、宿題(しゅくだい)を忘れる(わすれる)なんて。
✅
学生(がくせい)のくせに、宿題(しゅくだい)を忘れる(わすれる)なんて。
Students are not high‑standing; ともあろうものが expects a teacher, doctor, politician, etc. For someone of ordinary status, use くせに or にしては.
A good self‑check: if you can attach “of all people” naturally in English and the person holds an authority role, ともあろうものが is likely correct. ## Is ともあろうものが on the JLPT?

Contrast with くせに using the same noun. Write one sentence pair for each noun: first with ともあろうものが, then with くせに. Articulate why the first is shock, the second is contempt.
