Sendai Girls' Pro Wrestling
On January 17, 2016, Sendai Girls' Pro Wrestling held Sachiko's retirement event, during which she wrestled twice. First she and Chisako successfully defended the Sendai Girls World Tag Team Championship against Chihiro Hashimoto and Mika Iwata, relinquishing the title immediately after their win. Then Sachiko, along with ten other wrestlers taking part in the event, wrestled in a battle royal, which was won by Chisako, who pinned Sachiko to end her career. Sachiko and Chisako held possession of the WWWD World Tag Team Championship belts until February 28, when Meiko Satomura returned them to Diana.
