Quotation marks 「」 only sometimes being used for lines that are made in the first person?


For direct quotes (e.g. He said "_____", 彼は「＿＿＿」と言った), the quotes are
seemingly always used. But in Japanese, it's also quite common to voice
thoughts and feelings as if they are quotes being said in the first person,
and yet they don't seem to be given quotation marks.

Some examples

  1. あの人と付き合いたいなと思ってるでしょう。 (You're thinking "I want to get with that person", aren't you?)
  2. 大きくなったらお姫様になりたいって聞いたらまじで反吐が出るわ。(When I hear "I want to be a princess when I grow up", it makes me want to throw up)
  3. もうやってられない、諦めたいって思う人はこの社会に多くいる。 (There are many people in this society who feel "I can't do this any more, I want to give up")
  4. 私ならペテン師に騙されないって思ってるなら大間違いだ。 (If you're thinking "I won't be scammed by a conman", you're dead wrong).

In English, the lines said in the first person would essentially always be
given quotation marks (as I indicated in my translations). However, I don't
see them get quotation marks 「」 in Japanese really. Can they be given
quotation marks?

Basically, are quotation marks only supposed to be used when directly quoting
a person (e.g. he said "X", she screamed "Y", etc.), and not when giving a
hypothetical quote given in the first person? (e.g. he's probably thinking
"X")




You can think of these as "direct quotes without explicit quotation marks".
This is fairly common in Japanese because you can usually tell who's talking
by looking at first-person pronouns, keigo, sentence-end expressions (たいな,
だろうか, かしら), and so on. Since they are essentially direct quotes, of course
it's always fine to use explicit quotation marks for these examples. You
cannot use quotation marks when indirect quotes are being used.
