Original tekst - Japanski - はい、分かりました。

Hi Ian,
Does this mean: "Yes, I understand (I've understood)"?

The nuances are more like:

Okay, I see.

But "Yes, I understand" is an acceptable translation, I should think.
The "hai" here is not necessarily a "yes"-answer to a question asked by someone else, it just means "okay."
