On September 23, 2005, Ohka wrestled at an Ibuki event, where she and Kyoko Kimura faced Atsuko Emoto and Ayumi Kurihara in a Two Out of Three Falls match, during which she broke the anterior cruciate ligament in her left knee. Ohka underwent an immediate surgery on her meniscus and on February 16, 2006, also underwent a surgery to repair the ACL. The injury would leave her sidelined for almost two years. Despite her inactivity from in-ring competition, Ohka kept making semi-regular appearances for JDStar, including producing her fifth anniversary event on August 20, 2006. During early 2007, JDStar announced that it was going out of business, which led to Ohka hurrying back to make one final appearance for the promotion. On July 16 at JDStar's final ever event, Ohka wrestled rookie Misaki Ohata to a five-minute time limit draw in what was billed as a "prologue" to her real return match.
