Alternative for "my translation" (academic english)

Hi. I'm working on a paper that includes some excerpts translated from Japanese into English. After quotations, I know that people use the expression "my translation" to indicate that the translation was made by the author of the paper. Example: "It seems that 'quotation' (Tanaka 2010, p.2, my translation)."

However, if the text is written without first person pronouns, it seems odd to me to use "my translation". Does someone know another expression for that?

Thank you!!!
