GRe4N BOYZ 2026年 全国ツアー— GRe4N BOYZ Koriyama, Fukushima tickets

GReeeeN were Japan's longest-running unseen act. From their 2007 debut through 2024, the four-member group released commercial-chart ballads without ever appearing in music videos, television performances, or on-stage lighting cues — all four members had dental-medical careers, and anonymity served both creative distance and personal career compatibility. Kiseki, used in NTV's Rookies in 2008, became the generation-defining Japanese graduation song; Ai Uta ran on Pocky commercials; Haruka anchored graduation-season playlists across Japanese high schools. The 2024 rebrand to GRe4N BOYZ, announced as the group reopened themselves to live performance, dropped the eeee of the original name for a capitalized, abbreviated form. The 2026 tour is the first full nationwide run with face-visible members, and the setlist has been positioned around reworked GReeeeN-era material with live-harmony arrangements that were impossible to perform during the anonymous period. Venue philosophy is deliberately mid-size — the Zepp chain for standing-format nights, prefectural cultural halls for seated arrangements — specifically to preserve the acoustic intimacy of songs originally conceived for studio-only delivery. Foreign fans should prioritize the Zepp Haneda and LINE CUBE SHIBUYA dates for Tokyo access; regional dates fill smaller city culture halls that may require 2-3 hour train rides.
