Popular singer Namie Amuro, who has a strong fan base in Asia, said Wednesday she will quit show business next September.

"I, Namie Amuro, would like to take this opportunity to inform all of my fans of my decision to retire as of Sept. 16, 2018," the 40-year-old singer said on her website.

The surprise announcement by Amuro — known for megahits such as "Can You Celebrate?" and seen as a fashion phenomenon in the 1990s — came after she marked the 25th anniversary of her music career on Saturday and performed a commemorative concert over the weekend in her home prefecture of Okinawa.
