I need to obtain some additional information on Japanese introductions.
Do you mean the order of the first name and last name in Japanese names?
If that's what you mean then Yes, last names come before first names in Japanese, which is similar to many other Asian names. So we have, for example: 高橋 直希 - Takahashi Naoki Where Takahashi is the last name, and Naoki is the first name.
However, when Japanese introduce themselves to foreigners, it will be likely that they introduce their name in Western style (by putting their last name behind, making it Naoki Takahashi).
Therefore, I think you should not assume that the name coming first is always the last name. It is better if you learn and know common/popular Japanese last names so you won't be confused when they introduce themselves in either way.
