The most common and neutral pattern for marking the topic of discussion, thought, inquiry, or study. Used across all registers, from casual conversation to formal writing. The attributive form 〜についての modifies nouns. Distinct from 〜に対して, which marks a directional target or attitude rather than a neutral topic. Also distinct from 〜に関して, which is its formal/written counterpart.

Marks the target or direction of an action, feeling, or attitude — toward whom or what something is directed. Also used for contrast ('whereas / in contrast to') with のに対して. The attributive form 〜に対する modifies nouns. Distinct from 〜について, which simply marks a topic without directional nuance. In the contrast usage, the two clauses describe opposing or contrasting qualities. Not used for physical direction (use 〜に向かって for that).

Indicates that something is deliberately created or designed for a specific audience, market, or purpose. The emphasis is on intention and targeting — someone made a choice about who this is for. Distinct from 〜向き, which describes natural suitability rather than purposeful design. Frequently used with products, events, policies, and content. Compare: 子供向けの本 (a book published for children) vs 子供向きの本 (a book suitable for children).

Describes something as naturally fitting or appropriate for a particular person, purpose, or situation. The emphasis is on inherent suitability, not deliberate design intent. 〜向き is about nature/match; 〜向け is about targeting/design. Also used in set phrases like 前向き (forward-looking/positive), 右向き (right-facing), and 外向き (outward-facing), where it describes literal or figurative orientation rather than suitability.

Formal/written equivalent of 〜について. Used in official documents, academic writing, news reports, and business correspondence. Functionally nearly identical to 〜について but with a stiffer, more formal register. The attributive form 〜に関する is very common in document titles and headings. Not typically used in casual conversation — switching to 〜について in speech sounds more natural.

Expresses that someone acts in order to meet or fulfill another's expectations, hopes, demands, requests, or support. The noun before the pattern must be something that can be 'responded to' in a fulfilling sense — typically 期待 (expectations), 要望 (demands), 声 (voices), 希望 (hopes), 信頼 (trust), 支援 (support), ニーズ (needs). Not used for responding to questions (use 質問に答える instead) or replying to letters. The kanji 応える is preferred for this 'fulfill/meet' sense; 答える is for answering questions.

Used when a topic or issue becomes the center of debate, dispute, or controversy. The preceding noun is typically something contested — 問題 (problem), 法案 (bill), 土地 (land), 権利 (rights), 方針 (policy). The verb that follows is typically 議論する, 争う, 対立する, 討論する, etc. Distinct from 〜について: 〜をめぐって carries a strong connotation of conflicting opinions, competition, or struggle, not just a neutral topic. Also distinct from 〜に対して, which marks a directional target rather than a contested subject.

Expresses that something relates to or affects important, often serious matters — life, death, honor, reputation, future, fate, fundamental rights. The noun is typically weighty: 命 (life), 名誉 (honor), 将来 (future), 人間の尊厳 (human dignity), プライバシー (privacy), 存続 (survival). Distinct from 〜について, which simply marks a topic without the gravity. Also distinct from 〜に関する, which is a neutral formal 'concerning' — 〜にかかわる implies stakes or consequences. Note the separate pattern 〜にかかわらず ('regardless of'), which has a completely different function.
