Official artist and tour sources reviewed
back number identity and the verified 2026 Seoul dates
The page separates first-party artist facts, the official Asia schedule and TIXVOY marketplace availability so a future concert is not confused with a live listing.
The Gunma three-piece
The official profile says back number formed in Gunma in 2004 around Iyori Shimizu. The current line-up, in place since 2007, is Shimizu on vocals and guitar, Kazuya Kojima on bass and backing vocals, and Hisashi Kurihara on drums.
The same chronology connects the 2011 major debut to an established catalogue and records the sold-out five-dome in your humor tour 2023. These facts identify one specific band despite the ambiguity of the English phrase back number.
From five Japanese stadiums to Asia
Grateful Yesterdays Tour 2026 is described by the official profile as the band’s first five-stadium tour and largest production, with nine domestic performances. Those Japan dates ended on June 28 and are retained as history, not current stock.
The official additional-date announcement confirms the band’s first overseas performances in Taipei, Seoul and Hong Kong. Seoul is scheduled for September 12 and 13 at KINTEX Hall 9, with 16:30 doors and an 18:00 start on both days.
What the Seoul ticket facts do and do not prove
The official ticket page provides separate application routes for residents of South Korea and buyers living overseas. Its fan-club presale terms list standing admission at 17,000 JPY, a two-ticket limit and an age restriction that excludes children aged six or younger.
An official event announcement is not evidence that TIXVOY has inventory. This page exposes only listings actually synced to the marketplace; sales status, admission rules and organizer changes must be checked again on the official tour page.
