かんして・かんするConcerning; related to

かんして formally identifies the subject matter that a statement, inquiry, document, rule, or body of information is about. Use かんする when that subject-matter expression directly modifies a following noun.

What the marked noun does

Attach the pattern directly to the noun naming the subject matter. The rest of the sentence then gives information, asks a question, reports research, sets a rule, or performs another action concerning that subject. The marked noun is not automatically a person targeted by an action or something materially affected by it.

Core forms in use

These forms differ mainly in what follows them and in how compact or polite the expression is.

あたらしいしょうがくきんせいかんしてがくせいからおおくのしつもんせられた。

Many questions from students were received concerning the new scholarship system.

Analyze

けんきゅうりんかんいんかいあたらしいしんこうひょうした。

Analyze

かん gives the sentence a compact written style.

We revised the regulations concerning the management of personal information.

Analyze

けいやくこうしんかんしましてはたんとうしょからあらためてごれんらくいたします。

The heavier before-noun alternative

さいがいたいさくかんしてのりょうあつめた。

I collected materials concerning disaster preparedness.

Analyze

This is possible, though さいがいたいさくかんするりょう is usually more compact.

Formal subject matter versus an everyday topic

かんして is formal and document-friendly. について is the neutral choice for simply talking, asking, or learning about a topic, especially in ordinary conversation.

ともだちりょこうけいかくについてはなした。

I talked with a friend about our travel plans.

Analyze

The neutral topic form suits this everyday conversation.

Subject matter versus material involvement

かんして means that something is about a subject. When something actually affects, involves, or has serious consequences for that matter, use the form built from かかわる instead.

このはんだんかいしゃそんぞくかかわる

This decision affects the company's survival.

Analyze

The company's survival is materially at stake; it is not merely the topic of a statement.
