ONE Championship’s upcoming flyweight tournament field is set, and the opening round will take place at the promotion’s biggest event yet. “ONE Chmpionship: A New Era” takes place March 31 at Ryogoku Kokugikan in Tokyo and is the promotion’s debut in Japan. There are four title fights at the top of the card, plus the promotional debut of former UFC and Bellator lightweight champion Eddie Alvarez. But as if that wasn’t enough, the card also now will feature four first-round fights in ONE’s flyweight tournament, which includes former UFC flyweight titleholder Demetrious Johnson in his debut with the promotion. The promotion today announced the field and the brackets for the flyweight tournament. On one side, Johnson (27-3-1) takes on Yuya Wakamatsu (10-3), and Ivanildo Delfino (8-0) meets Tatsumitsu Wada (20-10-2)
