Shirai has been on WWE’s radar since first being contacted by them in 2016. A deal was reached last May but WWE discovered a heart issue so the offer was pulled. Shirai was later cleared after a full medical exam and her name had come up again in recent weeks. Dave Meltzer of the Wrestling Observer Newsletter listed her name as someone that was likely to get a WWE deal this year.
The rumors about her going to WWE heated up when she lost the Wonder of Stardom title on Wednesday night but the Observer reports that the title change had nothing to do with WWE and Stardom did not know she was leaving until Sunday.
The Observer reports that the company has made offers to other wrestlers from Japan in the UK, most notably Toni Storm. She is under a WWE UK contract and will be wrestling on the UK Championship Tournament show. There’s no word yet on when Shirai will start with WWE but it would seem likely that they would want her in the Mae Young Classic tournament that tapes in August.
