Haruyama made her professional wrestling debut for the JWP Joshi Puroresu promotion on January 23, 1998, facing Erika Watanabe at Korakuen Hall. Later that year, Haruyama won the Souseiseki Cup, JWP's tournament for rookies. Haruyama followed that up by winning another tournament the following year to become the new JWP Junior Champion. After graduating from the junior division, Haruyama became one of JWP's top wrestlers, winning back-to-back MVP Awards in 2003 and 2004 and culminating in April 2008, when she defeated Azumi Hyuga to win JWP's top title, the JWP Openweight Championship for the first time. Haruyama held the title for two years, making successful defenses against the likes of Kaori Yoneyama, Kyoko Kimura, Leon, Ran Yu-Yu and Yumiko Hotta, resulting in her winning yet another MVP Award 2008. Her reign ended in April 2010, when she lost the title to Nanae Takahashi in her ninth defense.
Meanwhile, Haruyama also excelled in tag team wrestling. After JWP Tag Team Championship reigns with Azumi Hyuga and Kaori Yoneyama, she formed the tag team "Harukura" with former junior division rival Tsubasa Kuragaki. The two won their first JWP Tag Team Championship in August 2007 and during their fourteen-month reign, unified the title with the new Daily Sports Women's Tag Team Championship in August 2008. Harukura held the titles for another eleven-month reign from December 2010 to November 2011. In April 2012, Haruyama regained the JWP Openweight Championship from her tag team partner Tsubasa Kuragaki and held it for six months, before losing it to Emi Sakura. In January 2013, Harukura started their third reign as both the Daily Sports Women's Tag Team and JWP Tag Team Champions with a win over the team of Arisa Nakajima and Command Bolshoi. After a seven-month reign, they lost the titles to Heart Move (Hanako Nakamori and Morii). On October 14, 2013, Haruyama defeated Kuragaki, who was making her final appearance for JWP, before her resignation from the promotion. After a short-lived partnership with Manami Katsu, Haruyama found a new partner in Ice Ribbon wrestler Aoi Kizuki, with whom she won the 2015 Tag League the Best.
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.
