6. Hisae Watanabe (MMA record: 19-6)
If you’ve ever seen a woman dressed in a two-piece leopard-print outfit knock another woman into unconsciousness in the middle of the ring, it was probably Watanabe. This deadly knockout artist is Japan’s best female striker with 11 TKO victories and 8 knockouts to her name.
Perhaps the most impressive win of her career was the fight that earned her the DEEP ladies lightweight title—a devastating knockout over previously unbeaten Satako Shinashi.
