The AWA Japan Women's Championship was a women's professional wrestling championship in the AWA Superstars of Wrestling promotion.
AWA Superstars of Wrestling's version of the AWA World Women's Championship was created in 1999, claiming the lineage of the original World Women's Championship of the American Wrestling Association (AWA).
However, in 2007 World Wrestling Entertainment (WWE) sued AWA Superstars of Wrestling promoter Dale Gagner over his use of the AWA name, which WWE owned.
In 2007, the title was renamed to the AWA Japan Women's Championship, following the inaugural champion Sherri Martel's death on June 15.
AWA Superstars of Wrestling, wanting to still recognize the current champion, recognized then-world champion Nanae Takahashi of Pro Wrestling Zero1 and Pro-Wrestling Sun as the first AWA Japan Women's Champion.
