Difference between にかんして and について?

Question

What is the difference between にかんして and について? Example usage would be much appreciated!

Answer 1

I found the answer on this website to be incredibly useful and explained the difference in a very understandable way: http://nihon5ch.net/contents/bbs-study/old/mie-bbs.cgi?s=86

However, I've quickly attempted to do a rough translation of the important parts of the answer so that even beginners who see this question can understand the difference. If able, I highly recommend reading the original post, however.

Usage Context/Literary Differences

When studying Japanese, 「〜について／〜についての」is studied before 「〜に関する／関して」. That is to say, 「〜について」is often used as a basic phrase in conversation.

In the case of foreign language study, when you translate into your own language and the words come out the same the difference can be difficult to understand. However, there is the following difference. 「〜について」→ Expression used often in conversation. 「〜に関して」→ Expression often used in written language.

About The Differences In Usage

1) The meaning of「○○について～する」

With verbs like 「話す」and 「考える」, for the reason of stating the topic or theme about which you intend to speak or think about first, 「について話す／考える」is used. In other words, if you were to say 「自分の夢について話す」, it would be because you are going to talk about things like 1) What you want to be, 2) Why you want to be that, 3) How you're going to become what you want to be.

2) The meaning of 「○○に関して〜する」

The meaning of 「関する」is "to be related", "to have a connection". Therefore, the expression 「○○に関して〜する」is used with the meaning of "In relation/connection to ○○ I/He/It will 〜". That is to say, much like 「について」it displays the theme or topic, however it is not restricted to just THAT topic. Of course 「○○に関して〜する」indicates a direct relation to ○○, however, it indicates strongly that related and connected topics will also be addressed.

If you picture the above description as an image, I think the difference can be understood easily.

If you were to say「日本語について研究する」, it would have the theme of 「日本語」and be restricted to content such as 「日本語の単語」、「日本語の文法」and 「日本語の発音」.

However, If you were to say 「日本語に関して研究する」, 「日本語」would be centered on, however it would point out that it is not "restricted" and areas peripheral to the topic are included.

For example, things like:

1. 「日本語を使った劇」
2. 「日本語で書かれた小説」

So, if you were going to be writing about Japanese festivals (What is interesting, what type of festivals you like, etc), you normally say "日本のお祭りについて書く". If however, you were to say 「日本のお祭りに関して書く」, it gives the impression that you will be centering around festivals but also touching on related topics. Additionally, it gives a much "stiffer" impression than "について".

（Ｂ）「～についての ＋ Noun」

1. 日本の文化についての話　を聞く
2. 日本の文化についての考え　を話す

（Ｃ）「～に関して ＋ Predicate」

1. 日本の文化に関して　勉強する　

（Ｄ）「～に関する ＋ Noun」

1. 日本の文化に関する論文　を読む

Answer 2

I think it's just important to look at the kanjis to get the meaning.

「に関する」means "to have a link with, to be related to".
「に就いて」means "concerning".

Those two meanings are different: one is concrete (ついて) one is meta (関して). Either you literally discuss the contents (ついて) either you discuss what revolves around (関して).

Examples:
GNU GPLに関する質問: Questions that are related to the GNU/GPL. (Can I sell GPL software? are there compatible licences? (subject is not the GPL))
GNU GPLについての質問: Questions on the GNU/GPL (Is the GPL legal? Can GPL be translated? (subject is the GPL))

Answer 3

In many contexts, they can both be translated to English as variations of "related", "as for" etc, but there are some differences...

As far as I know (and could find from different Japanese grammar sources), a few of the nuances are:

1. について means you are setting (in a restrictive manner) a theme/topic. It is preceded by something you are talking/thinking/writing about and often followed by a verb expressing such an action.

   日本語について研究する → "I study (about) the Japanese language" with a notion of topic restriction (e.g. Japanese grammar, Japanese vocabulary etc.)

2. に関して does not have that nuance of topic restriction, rather that of a relation (関係/関連) between the part that precedes and the part that follows. It is therefore used with a wider range of verbs.

   日本語に関して研究する → "I study things (closely) related to the Japanese language" with a notion of topic relation (e.g. plays or novels that are written in Japanese).

3. Usage: について is more common conversational Japanese. に関して is slightly more often found in writing.

4. Grammar: Although について and に関して are both followed by a predicate (verb or verbal noun), their "adjectival" variations (form attached to a noun) are different (についての and に関する):

   日本の文化について話す ▶　日本の文化についての話を聞く

   日本の文化に関して勉強する ▶　日本の文化に関する論文を読む

5. Also, I believe you would never see に関して ending a sentence, whereas it could be the case with について (and the copula omitted):

   「これから歴史の授業が始まります。今日は江戸時代について。」"History class will now start. Today's topic is the Edo era." [this example is my own, so please take it with some reserve]

Edit: a large part of the above examples are taken from the very link mentioned by phirru below: it is indeed a nice page on the topic. However, I found the explanations a lot more confusing than in my other grammar books (and decided not to go for a full translation).

Answer 4

に関して　=> Related to, in relation to について => Concerning, along, under, per
