Yoshiko Tamura is a Japanese retired professional wrestler. Tamura was trained by the All Japan Women's Pro-Wrestling (AJW) promotion, made her debut in September 1994 and worked for the promotion for three years, winning the AJW Junior Championship, before taking part in a mass exodus led by Kyoko Inoue and following her to the newly founded NEO Japan Ladies Pro-Wrestling promotion. Recognized as the "Ace" of NEO, Tamura performed with the promotion from its first event to the last, in the process becoming its most accomplished wrestler, winning the NEO Single and NWA Women's Pacific Championships a record seven times and the NEO Tag Team Championship three times. All in all, Tamura held the NEO Single and NWA Women's Pacific Championships for 2,074 days and successfully defended them 38 times. After being inducted into the NEO Hall of Fame, Tamura ended her sixteen-year career on December 31, 2010, retiring at the end of NEO's final event.

The World Championship Wrestling (WCW) Women's Cruiserweight Championship was a singles women's professional wrestling championship in World Championship Wrestling for smaller women. It was created as a joint venture between WCW and GAEA Japan. The weight limit for the women's cruiserweight division was 130 lb. The first champion was crowned in a four-woman tournament that began on an episode of WCW Monday Nitro on March 31, 1997 and concluded on April 7, 1997. Since the tournament final was only shown on WCW Main Event, and the results were never mentioned on WCW television again, it is speculated that the title was created solely to be used by the GAEA promotion in Japan. In fact, the title was defended and changed hands twice in Japan before being abandoned in early 1998.
