‘One Piece’ Star Hospitalized for Injury: Kappei Yamaguchi Shares Update

One Piece star Kappei Yamaguchi, who voices Usopp in the Japanese anime series One Piece, is on the mend following a recent hospitalization. In back-to-back social media posts last week, the actor revealed that he was hospitalized and underwent surgery after he suffered a painful exercise-related injury.

Yamaguchi revealed his health scare in a May 29th post to X (formerly Twitter), telling fans, “I’m going to be hospitalized for a bit starting today. It’s for surgery on my shoulder because I overdid it weightlifting.” He went on to joke that he would “come back with cyborg shoulders,” adding, Let’s stay lively and energetic.”

In a follow-up post on May 30, the actor informed fans that he “was hospitalized” and was set to undergo surgery the following day, adding, “after that I have to go without food for a whole day.”

News of his hospitalization sparked a flurry of well wishes for the actor. Replying to his post, one follower wrote in a translated message, “Please take care of yourself. I wish you a speedy recovery!” Somebody else added, “Take care of yourself! I hope your surgery goes well!”

“Thank you for all your messages of support,” Yamaguchi wrote on May 30 amid the show of support. “I did too much weight training and tore my shoulder, and since it’s an area that doesn’t heal naturally I had to have surgery. So, it’s not that important and I’m sorry for worrying you. Starting tomorrow, I’ll be a cyborg with only my shoulders hacked.”

In a June 1 health update, the actor shared a photo of himself sporting a new accessory: an arm cast. He told his followers, “Even if your dominant hand is not convenient, Humans learn all kinds of skills.”
