Koji Ueno

How this identity was checked

The official the HIATUS biography names ウエノコウジ as the bassist. The official KIKKAWA KOJI LIVE 2026 page also places ウエノコウジ under Bass. The shared Latin given name Koji can make automated matching risky, but the full names are different: Koji Ueno is ウエノコウジ, while Koji Kikkawa is 吉川晃司. Official role credits confirm that they are two performers in one tour lineup.

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

Ueno’s work with the HIATUS is a central part of his band career. His appearance on Kikkawa’s official tour page shows another side of his live work as a support bassist. The two credits are complementary and help fans trace his performances across band and touring settings.

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.
