Lee Jae Jin

Lee Jae Jin (이재진) is one of the structural reasons FT Island still works as a live band nearly two decades in. Officially positioned by FNC Entertainment as bassist and vocalist, he supplies both the low-end drive and the second-line vocal lift that keeps the trio format balanced around Lee Hong Gi and Choi Min Hwan.

That role becomes clearer when the group moves back into touring mode. FT Island's 2026 FaTe routing across Asian markets was not built on nostalgia alone. It was built on a band that can still play. Jae Jin sits at the center of that credibility, and his own catalog extends beyond group work through the Japanese solo mini album scene.27. For HITKULTR, he reads less like a supporting member and more like one of the key musicians keeping Korea's idol-band lane durable.
