After releasing their second Japanese single "Fallin' Flower" in April 2020, Seventeen announced their second Japanese EP 24H, which was to be promoted with a title track of the same name as a pre-release single.[1] The song "24H" was released on Japanese radio through the station Tokyo FM School of Lock on August 18.[1] It was digitally released alongside its accompanying music video on August 24.[2]
24H accumulated a pre-order volume of 450,000 copies in Japan and sold 240,000 copies during its first week of release.[3] It debuted at number one on the Oricon Albums Chart for the week of September 7 to 15, 2020.[3] Following Seventeen's other successes atop the chart with their Korean-language EPs You Made My Dawn and Heng:garæ, as well as their third studio album An Ode, this achievement marked Seventeen as the first foreign international male artist to top the Oricon weekly album chart with four consecutive albums.[3]
