Jewels 13th Ring and 14th Ring

Background

Due to the 2011 Tōhoku earthquake and tsunami, Jewels 12th Ring was canceled. As a result of this, Jewels decided to change their planned schedule in order to combine Jewels 13th Ring and Jewels 14th Ring into a single date and location, the first one in the afternoon and the second one in the evening, and serve as fundraisers for Japan's earthquake relief and reconstruction efforts. The location and date originally planned for Jewels 14th Ring will be used for Jewels 15th Ring. As part of the relief efforts of the 2011 Tōhoku earthquake and tsunami, 13th Ring and 14th Ring are part of the Fight for Japan charity, a collaborative effort from several Japanese combat sports organizations.

The first four bouts announced were two kickboxing matches and two MMA matches on April 13, 2011 (2011-04-13). In a notable development, Yasuko Mogi, producer of MMA promotion Valkyrie, was present during the press conference to announce that the MMA bouts would be part of the theme Jewels vs Valkyrie, where fighters representing their respective promotions would face each other.

On April 23, 2011 (2011-04-23), Jewels added Mika Nagano vs. Emi Murata to the 14th Ring card and announced three more bouts for the 13th Ring card.

Four more matches were announced on May 1, 2011 (2011-05-01), two MMA bouts for 13th Ring and two grappling bouts for 14th Ring.

On May 6, 2011 (2011-05-06), Jewels added one shoot boxing match and one more grappling match to 14th Ring.
