[Translation from Japanese to English ] Sorry to mention so many times, but Yu is Ms. Yamada, not Mr. Sasaki. I know...

Original text

何度も申し訳ないのですが、Yuは、Ms.Yamadaのことです。Mr.Sasakiではありません。Mr.TanakaはYoですし、似た名前ばかりで混乱させてしまいますが、これらは日本人の名前として特別多いわけではなく、全くの偶然です。Ms.Yamadaには私から連絡しておきます。

Translation / English

Sorry to mention so many times, but Yu is Ms. Yamada, not Mr. Sasaki.
I know it's very confusing, where Mr. Tanaka's first name is Yo, but these names are not so common in Japan and it's only a coincidence. I'll contact Ms. Yamada myself for this case.

Translation / English

I hate to repeat it, but Yu is Ms.Yamada and is not Ms. Sasaki.
Mr.Tanaka is Yo. I made you confused by the similar names, but they are not especially many
as the Japanese name. It is just a coincidence.
I will contact Ms Yamada.

Mr.Takaka is Yo. It might be confusing as Japanese names sound similar.
But these names are not specially popular and just an coincident.
I will contact Ms. Yamada about this.
