In Japanese, how do you tell the reader that a quotation is literally translated from the original when the original sounds strange?


In cases where the original wording of a quotation sounds strange, and thus
the Japanese translation of it sounds unnatural, my advisor says I need to add
a note each time in my academic paper to tell the reader that the quote is
literally translated to Japanese from unusual wording in the original.

Is there a standard format for this in Japanese academic writing? Or how can I
indicate this to the reader so he/she doesn't assume I mis-translated?

For example, my translation:

> 保子夫人が回復したという電報の知らせを受けたとき、宮部は「…もしかしたらあなたが危篤状態だったのかもと思い、 **電撃** を受けた」と述べ、

from the English original wording:

> When Miyabe received a cablegram notifying him that his wife was feeling
> better, he confessed that “it gave me an **electric shock** , intimating you
> had been once perhaps very seriously ill,”

"It gave me a shock" sounds normal in English but Miyabe's extra-dramatic
"electric shock" is not common, so how can I let the reader know that 「電撃」 is
a translation of his specific word choice? Should I put a brief note in
parentheses inside of the quotation, like this:

> 保子夫人が回復したという電報の知らせを受けたとき、宮部は「…もしかしたらあなたが危篤状態だったのかもと思い、電撃（
> **宮部の創造的な原作に忠実である翻訳** ）を受けた」と述べ、




I think 電撃 is not so strange as a translated material, but anyway...

I'm afraid I don't know the standard way to assert your translation of a
certain expression is correct without disclosing the original English phrase.
Something like `（この部分は原文を直訳したもの）` might work, but that's annoying and
uncommon.

In general, it's a common practice to specify the original English wording
using 訳注 (translator's note) like this:

> 「……危篤状態だったのかもと思い、電撃 **（訳注：原文はelectric shock）** を受けた」

If you really need to add a long comment about a certain phrase, do so in a
footnote:

> 「……危篤状態だったのかもと思い、電撃[訳注1]を受けた」と述べ、……  
>  --------  
>  訳注1: 原文はelectric shock

or at least outside the quotation to preserve readability, depending on the
style guideline you have to follow.

> 「……危篤状態だったのかもと思い、電撃を受けた」と述べ（注：「電撃」は原文のelectric shockを直訳したもの）、……
