Early life
Tsuji was born on December 11, 1974 in Hirakata, Osaka, Japan. She graduated from the prestigious Chukyo Women's University; a university notable for its wrestling family. During her time there, Tsuji placed third in Women's Freestyle Wrestling (51 kg) in the 1997 Asian Championship.

Mixed martial arts career
Tsuji spent the majority of her career competing in the now-defunct Smackgirl promotion. She debuted with defunct promotion Ax on December 26, 2001 in the event Ax - Vol. 2: We Want To Shine with a victory by submission (armbar) over the previously undefeated Ikuma Hoshino, who at the time was the most accomplished female Japanese MMA fighter. This would be Hoshino's only loss in her MMA career.

Tsuji debuted in Smackgirl at Smackgirl - Royal Smack 2002 on April 7, 2002, defeating Hiromi Oka by submission due to a rear naked choke. Including her debut, Tsuji would go on a winning streak of 8 consecutive victories; in the process winning the Smackgirl Japan 2002 Cup Middleweight Tournament on June 28, 2005. In her ninth professional bout, she faced Brazilian fighter Ana Michelle Tavares. Tavares defeated Tsuji with a triangle armbar submission in Tsuji's debut for the Deep promotion at Deep - 11th Impact on July 13, 2003. In this match, Tsuji injured her left shoulder. This was Tsuji's first defeat in MMA. She avenged this loss years later.

After her first loss, Tsuji won her next four fights and then faced Hisae Watanabe at Smackgirl - Road to Dynamic!! for the first Smackgirl Lightweight Championship on June 28, 2005. Tsuji won the title after defeating Watanabe by armbar at 3:51 of the first round. She would go on to successfully defend the title five times until the demise of the Smackgirl promotion.

On September 6, 2007, Tsuji would get the chance to face Tavares again. At the event Smackgirl - Queens' Hottest Summer, Tsuji was able to avenge her only loss at the time by defeating Tavares via KO at 4:47 of the first round. After defending her title for the last time against South Korean Seo Hee Ham, Tsuji debuted in Valkyrie at the promotion's inaugural event Valkyrie 1 on November 8, 2008, where she defeated Mei Yamaguchi by decision. Tsuji became the first Valkyrie Featherweight Champion on April 25, 2009 by defeating American fighter Kate Martinez.

Her 14-fight winning streak came to an end on February 11, 2010 when she rematched Mei Yamaguchi, who this time was able to defeat Tsuji with a rear-naked choke in only 76 seconds. This was just the second time that Tsuji was defeated and the first time that she was defeated by a fellow Japanese fighter. This is considered one of the biggest upsets in the history of women's mixed martial arts.

Having recovered from surgery on her knee and shoulder, Tsuji returned to MMA in a Jewels vs. Valkyrie bout against Saori Ishioka at Jewels 15th Ring on July 9, 2011 in Tokyo, Japan. She defeated Ishioka by unanimous decision.
