Number_i has announced their first-ever world tour, which will begin with a five-dome tour across Japan before expanding overseas in 2027.

The tour will be divided into two chapters: "Chapter 1: Japan," launching in October 2026, and "Chapter 2: Asia & North America," scheduled for 2027.

The Japan leg, titled "Number_i LIVE TOUR No.III," will feature performances at the five major domes in Hokkaido, Tokyo, Aichi, Osaka, and Fukuoka—marking Number_i's first time headlining all five venues as part of a single tour.

Additional tour details, including dates and ticket information, will be announced at a later date.
