I'm mobile right now so I can't use the quote function. But Step, James said "Let me introduce myself, Hajimemashite, James Jirayu desu, yoroshiku onegaishimasu" which is the standard japanese greeting (i.e. Pleased to meet you) but literally, it translates to "for the first time (of meeting you) I am James jirayu, please take care of me/or I leave myself to your care" Oh and the song he sang is "Sakurazaka" by Masaharu Fukuyama, one of the most popular Jpop singers/actors of the semi older generation hahaha. I would say Fukuyama is comparable to Tik, and a bit older.
