Girl group Le Sserafim's debut Japanese EP “Fearless” ranked No.1 on Japan’s Oricon chart on Thursday.

Over 132,000 units of the EP were sold in just one day after its release Wednesday.

"Fearless" is now the highest-selling debut Japanese release for a fourth-generation K-pop girl group based on first-day sales figures.

Fourth-generation girl groups typically refer to those that debuted in or after 2019.

The Japanese EP has three tracks — "Fearless -Japanese ver.-," "Blue Flame -Japanese ver.-" and "Choices."

The Korean version of "Fearless" and the group's EP "Antifragile" (2022) previously topped Oricon charts last year.
