About two decades ago, he got caught slipping before leaving the relationship.
In retaliation, his then gf shanked his ass.
He drove to the hospital on a scooter with the knife still in him.
Since Japan is funny about shame, he basically had to apologize for getting stabbed.
It made him more popular than ever - fans were interested in his return.
He put New Japan on his back, bringing the wrestling to the forefront after Inoki's MMA boner almost destroyed the company, and that's how Tana ate a scandal like a Scooby snack.
Shibata and Taichi have also recovered from adultery scandals, which are a little more damaging in Japanese culture.
