In a notable achievement, King & Prince's debut best album, "Mr.5," clinched the prestigious first position on the 2023 Billboard Japan Hot Albums chart. Released on April 19, "Mr.5" achieved the remarkable feat of surpassing one million in sales in less than three weeks, solidifying its status as the fastest-selling album of the year.

It's noteworthy that "Mr.5" marked this achievement during a time when King & Prince had five members. However, post-release, three members, Yuta Kishi, Sho Hirano, and Yuta Jinguji, made the decision to depart from the group and join TOBE forming the group Number_i as 3 members. Despite these changes, "Mr.5" stands as a testament to King & Prince's enduring popularity among fans.

Snow Man's 3rd album, "i DO ME," secured the second position, maintaining a consistent presence on the chart for a whole 28 weeks.

Stray Kids made a strong impact, claiming two spots in the top 6. Their Japanese 1st EP, "Social Path (feat. LiSA) / Super Bowl -Japanese ver.-," claimed the third spot with significant CD sales success.

SEVENTEEN made a notable impact as well, securing two spots in the top 5. "FML" claimed the fourth position, while "ALWAYS YOURS" secured the fifth spot, recording commendable CD sales. SEVENTEEN's consistent chart presence highlights their robust fan base in Japan and their enduring musical influence.

In 2023, the Billboard Japan Hot Albums chart paints a vivid picture of the dynamic Japanese music scene. King & Prince and Snow Man emerge as frontrunners, dominating the charts throughout the year. Notably, their chart dominance is complemented by the strong presence of Korean acts, showcasing the diverse and impactful nature of the music landscape in Japan.
