Rebounding from her stunning upset loss to Mei Yamaguchi, Tsuji put on a dominant performance, easily besting promotional postergirl Saori Ishioka after two rounds.
Also featuring on one of the most stacked cards in recent Women's MMA history: Megumi Fujii put an aggressive beating on Mika Nagano for the second time, Seo Hee Ham bested a game Mei Yamaguchi and Hitomi Akano utilized judo and leglocks to edge out Roxanne Modafferi. Full results after the break.

Cornered by Strikeforce heavyweight Josh Barnett, Megumi "Mega Megu" Fujii was also in splendid from - putting on a highly aggressive performance in her second victory over 2009 Jewels 54 kg Rough Stone Grand Prix champion Mika Nagano.

Unfortunately, Jewels officials decided that the bout was to be contested under limited rules, which prohibit striking to the face on the canvas. Given the she did not have to worry about strikes on the mat, Nagano's defensive grappling was good enough to see her through to the final bell. Had the bout been contested under normal MMA rules, it would be hard to imagine the bout making it to the judges.
South Korean kickboxer Seo Hee Ham (pictured below, right) picked up her third successive win of the year, besting the highly rated Valkyrie featherweight ace Mei Yamaguchi. Ham's cracking kicks punished the legs and body of Yamaguchi through the two round bout, the grappler unable to secure a much needed takedown against the striker. Yamaguchi was able to trade competitively with Ham early on, but a clear power difference meant that she was fighting a losing battle.

The bout was originally booked for Sengoku's end of year event in 2010 but Modaferri was struck down with illness the day of the event.
In a battle of the Jewels goliaths, Hiroko Yamanaka battered Bolormaa "Esui" Erdenebileg before snatching the armbar victory midway through the second round. Despite their similar size, Yamanaka had a clear power and technique advantage, beating her Mongolian foe into the corner and softening her up for the submission.
