Singer and actor IU will hold a world tour for the first time in five years.

IU is set to perform four times at the KSPO Dome in Seoul on March 2-3 and March 9-10, kicking off the "IU H.E.R. World Tour Concert," according to IU's agency, EDAM Entertainment on Wednesday. The meaning of the concert title will be revealed later, the agency said.

IU will tour 18 cities in 12 countries including Seoul; Yokohama, Japan; Taipei, Taiwan; Singapore; Jakarta, Indonesia; Hong Kong; Manila, the Philippines; Kuala Lumpur, Malaysia; London; Berlin; Bangkok; Osaka, Japan; Newark, New Jersey; Atlanta; Washington; Rosemont, Illinois; and Los Angeles and Oakland, California. More venues will be added later.

IU's last concert tour, "Love, Poem," took place in 2019.

Meanwhile, IU is also holding a promotion to release her new song, "Love Wins," on Jan. 24 ahead of the world tour. The song comes just over two years after her last release, “Pieces.” On Wednesday, the singer raised fans' expectations by releasing posters and previews that appeared to be scenes from her upcoming music video. The music video features IU and her close friend V from BTS, and is directed by Um Tae-hwa, who directed the film "Concrete Utopia," released last year.
