Ken Watanabe, an actor best known for his lead role in Broadway’s The King and I, has sadly been diagnosed with early-stage stomach cancer.

The 56-year-old star’s rep confirmed the news to People on Tuesday, Feb. 9, adding Ken has postponed his upcoming return to Broadway to instead focus on his health.

“I would like to ask for your understanding that the start of my performance in New York will be a little delayed,” Ken said in a statement released earlier this week. Prior to his diagnosis, Ken was expected to return to The King and I in March.
