In February 2022, Kozo KATO (Katokozo) and Ifuku Yobun (Ifuku Hirofumi) formed the “Old Rookie Unit” with a high performance and a sense of running music. Immediately after the formation of the unit, the unit has attracted attention in various fields and is actively engaged in live-activities and CM tie-ups in various regions, mainly in Fukuoka. The first one-man LIVE was held in March 2023, when Kazuaki Yamada and Atsuzane Yamamoto were added to the support members and the live activities were carried out as a four-person organization. Although Ifuku withdrew in October 2023, the momentum has not declined, and it has gained support from a wide range of generations, both young and old. Currently, he is also in charge of the theme song of the 2023 Nagasaki International Television “Yabarabi Genki Declaration.”
