Kaori Yoneyama
On April 5, 2015, Haruyama defeated Arisa Nakajima to capture the JWP Openweight Championship for the third time. She lost the title to Command Bolshoi on July 11. Following the loss, Haruyama announced she would retire from professional wrestling on December 27. As part of her road to retirement, Haruyama reunited with the now freelancer Tsubasa Kuragaki, but the two failed to capture the Daily Sports Women's Tag Team and JWP Tag Team Championships on September 22. In October, Haruyama and Kuragaki made it to the finals of Pro Wrestling Wave's 2015 Dual Shock Wave tournament, contested for the Wave Tag Team Championship, but were defeated there by Ayako Hamada and Yuu Yamagata. On December 27, Haruyama wrestled twice during her retirement event, first teaming with Tsubasa Kuragaki to defeat Command Bolshoi and Kaori Yoneyama in Harukura's final match together as a tag team and then defeating Kuragaki in the final match of her 18-year career.
