An atomweight fight featuring Mei Yamaguchi has been added to the ONE: ‘A New Era’ card. The Japanese veteran faces Kseniya Lachkova in one of 16 fights now confirmed for March 31st.

Yamaguchi (18-11-1) was scheduled to face Bo Meng at ONE: ‘Call to Greatness’ last month but the Chinese fighter withdrew at the last minute. Instead the two time atomweight title challenger spent her time in Singapore training at Evolve MMA:

Yamaguchi has been matched with promotional newcomer Lachkova (9-2). She hails from Russia and is riding a four fight winning streak which has included one win in China.

ONE: ‘A New Era’ is set for the Ryogoku Kokugikan in Tokyo and is being hailed as the biggest card in the promotion’s history. It features former UFC champions Demetrious Johnson and Eddie Alvarez as well as four title fights.

Eduard Folayang defends his lightweight title against Shinya Aoki in the main event while Angela Lee challenges Xiong Jing Nan for the strawweight title in a fight that was originally booked for ONE: ‘Heart of the Lion’ last November.

Meanwhile Aung La Nsang defends his middleweight belt against Ken Hasegawa in a rematch while Kevin Belingon puts his bantamweight strap on the line against Bibiano Fernandes in a trilogy title bout.
