Three days before its first-ever event in Japan, the fast-growing ONE Championship fighting organization held a gorgeous news conference at a luxury Tokyo hotel on Thursday night.

Indicating the promoter's seriousness for one of the largest combat sports markets in Asia, ONE prepared a bout lineup that is arguably the richest in its eight-year history with several championship matchups for the Sunday event at Ryogoku Kokugikan.

The event, which is dubbed "ONE: A New Era," will kick off at 3:30 p.m. with preliminary matches.
