The London production ran for 21 years and 8,949 performances, while the Broadway production ran for 18 years and 7,485 performances, making "Cats" the longest-running musical in both theatre districts for a number of years. "Cats" has since been revived in the West End twice and on Broadway once. It has also been translated into multiple languages and performed around the world many times. Long-running foreign productions include a 15-year run at the Operettenhaus in Hamburg that played over 6,100 performances, as well as an ongoing run in a purpose-built theatre in Japan that has played over 10,000 performances since it opened in 1983.
