“〜jou”: On the Level of / In Terms of 〜 (noun ＋ 上) [JLPT N2]

Content by NTJ Kuma · Nihongo to Japan editorial team · Updated July 27, 2026

“health reasons,” “a work matter,” “necessary for safety” — matters on a certain level

「健康上の理由で休みます」 — framing a topic on ‘a certain dimension'

「健康上の理由で、しばらく休職します」 (I'll take leave for health-related reasons) — 「noun ＋ 上（じょう）」 means “on the dimension/aspect of ～, as regards ～”: framing a matter within a certain domain or viewpoint. This written N2 regular needs special care with its reading — 「上」 read 「じょう」 means “aspect,” but read 「うえ」 (〜上で) means “after/on the basis of,” an entirely different sense. This guide sorts it out.

Core: as regards a certain dimension, viewpoint (noun ＋ 上 = じょう)

「(noun) ＋ 上（じょう）」 = “on the dimension/aspect of ～, as regards ～” — framing the topic within a certain domain, angle:

• 健康上の問題 (a health-related problem) — on the health dimension.
• 法律上は問題ない (legally there's no problem) — from the legal angle.
• 経験上、これはうまくいかない (from experience, this won't work).

Feel: “as regards ～／on the ～ dimension” — the core is “viewing from a certain domain, standpoint, angle.” Common collocations: 健康上・法律上・仕事上・立場上・経験上・教育上・安全上・都合上・歴史上. It's a formal, written expression.

Attachment rules

Examples in context

• 安全上の理由により、撮影は禁止です。(For safety reasons, photography is prohibited.)
• 仕事上の付き合いで、飲み会が多い。(Due to work-related dealings, there are many gatherings.)
• この計画は、予算上、実現が難しい。(This plan, budget-wise, is hard to realize.)
• 歴史上、これほどの偉業はない。(Historically, there's no feat this great.)
• 都合上、日程を変更させていただきます。(For scheduling reasons, allow us to change the dates.)

⚠️ Common mistakes to avoid

① Reading distinction: 「上（じょう）」 = aspect, 「上（うえ）で」 = after/on the basis of. The key trap. noun ＋ 上（じょう）= on the ～ dimension (健康じょうの理由 = health-related reasons); verb た-form／noun の ＋ 上（うえ）で = after ～／on the basis of ～ (確認したうえで返事する = reply after confirming; 書類のうえで = on the documents). The same 「上」, different readings, worlds apart: じょう = dimension, うえ = after/on the basis of. Check what precedes (noun directly = じょう aspect; verb た-form/noun の = うえで after).

② 「上（じょう）」 leans written, formal; colloquially use 「〜的に」「〜の面で」. 「〜上（じょう）」 is formal, stiff, seen mostly in rules, official documents, news, academia (安全上・法律上・業務上). For a casual “as regards ～,” natives more often use 「〜的（てき）に」 (健康的に = health-wise) or 「〜の面で」 (コストの面で = cost-wise). In formal writing 上（じょう） reads professional; in chat 〜的に／の面で is more natural.

③ 「〜上（じょう）」 attaches only to abstract nouns — don't attach freely. It attaches mostly to abstract domain nouns (健康・法律・仕事・立場・経験・安全・教育・歴史・予算…), meaning “that dimension.” Not to concrete objects (×机上じょう — 「机上」 read きじょう is a different word) or verbs. When no fitting abstract noun comes to mind, don't force 「上（じょう）」.

💡 Quick takeaway

「noun ＋ 上（じょう）」 = on the dimension/aspect of ～, as regards ～, framing the topic within a domain, viewpoint (健康上・法律上・仕事上・立場上・経験上). A formal, written expression. Three points: ① the key is the reading distinction — noun ＋ 上 reads 「じょう」= aspect, while verb た-form/noun の ＋ 上 reads 「うえ」= after/on the basis of (〜うえで), worlds apart — don't confuse them; ② it leans written and formal, colloquial “as regards ～” mostly uses 「〜的に／〜の面で」; ③ it attaches only to abstract domain nouns (健康・安全・法律…). See 「〜上」 and first judge the reading (preceded by a noun = じょう aspect, by a verb た-form = うえで after), and you won't misread. To express “as regards the ～ dimension” in formal writing, noun ＋ 上（じょう） is the most fitting.

❓ Questions you might have

Q: How do I tell 「上」 read 「じょう」 from 「うえ」? How do the meanings differ?

This is 「上」's most important reading/meaning distinction, judged by what precedes, with wholly different senses:

① noun ＋ 上（じょう）= on the ～ dimension/aspect (as regards ～): attaches to an abstract noun, read 「じょう」, meaning “viewing from that domain/angle” — 健康上（じょう）の理由 (health-related reasons); 法律上（じょう）は問題ない (legally no problem); 経験上（じょう） (from experience); 安全上（じょう） (safety-wise). It's a suffix turning a noun into “the ～ aspect.”

② verb た-form／noun ＋ の ＋ 上（うえ）で = after ～／on the basis of ～ (a premise): attaches to a verb た-form or noun ＋ の, read 「うえ」, meaning “after doing ～ (then)” or “on the premise/basis of ～” — よく考えた上で（うえで）決める (decide after thinking it over); 両者合意の上で（うえで） (on the premise of mutual agreement); 書類の上では（うえでは）問題ない (on the documents there's no problem). It marks “after, on the basis of.”

Trick: preceded by ‘an abstract noun directly' → じょう (aspect); preceded by ‘a verb た-form' or ‘noun ＋ の' → うえで (after/on the basis of). E.g., 「健康上」 (けんこうじょう = health-wise) vs 「確認した上で」 (かくにんしたうえで = after confirming). One is “dimension,” one “after/on the basis of” — different reading and sense, a much-tested N2 reading trap, so keep them straight.

Q: 「〜上（じょう）」「〜について」「〜の面で」 all mean ‘about/as regards ～' — how do I choose?

All relate to “a certain aspect/topic,” but differ in function and register:

① noun ＋ 上（じょう）= as regards the ～ dimension/aspect (written, formal, stressing ‘judging from a certain domain, viewpoint'): 予算上、無理だ (budget-wise, it's unfeasible); 教育上よくない (educationally bad). It leans formal, written, common in rules, exposition, objective in tone.

② 〜について = about ～ (simply pointing out the ‘topic content,' neutral, general): 予算について話し合う (discuss the budget — the topic is “budget”). It only flags “what the topic of discussion is,” without the “judging from a dimension” feel.

③ 〜の面（めん）で = in the ～ aspect (a colloquial synonym, more plain): 予算の面で問題がある (there's a problem on the budget side); コストの面で有利 (advantageous cost-wise). Close to 「上（じょう）」 in meaning (both “the ～ aspect”), but more colloquial, plainer, common in daily talk.

Test: written, formal “as regards ～” → 上（じょう）; colloquial “in the ～ aspect” → の面で／〜的に; simply “about a topic” → について. So for a paper or official document 「〜上」 reads professional, in chat 「〜の面で」 is more natural, while 「について」 purely flags the topic without the “dimensional judgment” feel.
