Tunacao, a Japanese based Filipino fighter who fights out of the Shinsei gym, spent 5 rounds with Inoue as the Japanese youngster continued the preparation fro his WBO Super Flyweight world title bout against Argentinian veteran Omar Andres Narvaez (43-2-1, 23).
From what we understand Tunacao was selected as a sparring partner for several reasons. Not only is the Filipino a tough fighter, having given Shinsuke Yamanaka a really tough bout back in April 2013, but like Narvaez he is also a southpaw and has been competing in around the Super Flyweight and Bantamweight divisions for several years. It appears that the southpaw stance of Tunacao is the key to the sparring with Inoue learning more about fighting southpaws, something he has yet to actually do in a professional bout.
From Inoue's blog it seems Tunacao will be in his camp for 15 days with other notable fighters being brought in to further help with his training, at the moment however it seems those fighters are being kept under wraps for a few days.
