Nigerian Ridwan Oyekola is ranked fourth in the Japanese featherweight division as Japan Boxing Commission released its new rankings for January on Jan. 30.

The 25-year-old Oyekola beat Thailand’s top-ranked lightweight Manat Sopatip with a first-round technical knockout on Jan. 22 in Japan’s southernmost prefecture of Okinawa for his third straight victory in Japan.

He has been fighting out of Okinawa’s Hiranaka Boxing School Gym since last September. Oyekola has an 11-1-1 win-loss-draw tally with six KOs.

Former amateur star Hayato Tsutsumi of Shisei Boxing Gym is also ranked sixth in the featherweight division as he decisioned Pete Apolinar of the Philippines on last New Year’s Eve for his second straight win after turning pro last July.

Among the 13 weight divisions from the minimumweight to middleweight, seven divisions are without champions as the then flyweight, super bantamweight, featherweight and super lightweight champions relinquished their titles, respectively.
