Koji Kikkawa

How this identity was checked

The official biography uses the Japanese name 吉川晃司 and documents his debut in 1984. Koji Kikkawa is the Latin-script form of the same name. COMPLEX, THE GROOVERS and the touring musicians are separate artists connected to Kikkawa through band history or live collaboration.

This profile follows the names and roles stated by the cited official or label sources. A tour credit describes the part a musician performs on that tour; it does not make that musician another name for the headliner or for an entire band. Career facts are kept separate from dates, venues, ticket areas, prices and delivery details that may change.

Career and performance relationships

Kikkawa has an established solo career as a singer and actor, and his official biography also describes his work with COMPLEX as a separate part of that career. On the 2026 HIGHER! HIGHER! tour, the official event page bills Kikkawa as the artist and lists each supporting musician by instrument.

How to read the ticket information

An official tour credit identifies who is scheduled to perform, while each linked TIXVOY event page provides the date-specific buying details. Before purchasing, check the exact performance, venue, start time, seat or standing area, quantity, delivery method and seller notes. If a lineup changes, follow the latest official event announcement and the updated event page.
