JO1 discography

Japanese boy band JO1 has released three studio albums, one video album, seven singles, thirty one promotional singles, and sixteen music videos with Lapone Entertainment. Formed through the reality competition show Produce 101 Japan, JO1 debuted in 2020 with the single Protostar and the Japan Hot 100 number-one song "Infinity". The single made the group the seventh Japanese artist to sell over 300,000 copies of a debut single in the first week. It was followed by the single Stranger and its lead track "Oh-Eh-Oh", both of which peaked atop the Oricon Singles Chart and the Japan Hot 100, respectively. The group's first studio album, The Star (2020), debuted at number two on the Japan Hot Albums chart.

In 2021, JO1 extended their streak with three number-one singles—Challenger, Stranger, and Wandering. The latter earned the group's first double platinum certification from the Recording Industry Association of Japan (RIAJ) for shipments of over half a million units. The singles were followed by Kizuna (2022), which became the group's first number-one album on the Japan Hot Albums and Oricon Albums Chart. JO1's number-one album streak continued in 2023 with Equinox, which was preceded by the singles Midnight Sun and Tropical Night. The former marks the group's first single to sell more than 600,000 copies in its first week on Billboard Japan, while the lead track, "SuperCali", lasted two weeks on the Japan Hot 100's top six.
