Our Story with Atelier Z
Our Visit to Atelier Z in Japan - 2024
In 2024, we had the opportunity to visit the Atelier Z workshop in Japan and meet Kokichi "Johnny" Motohashi and the Atelier Z team.
Seeing the workshop and discussing the instruments in person gave us a deeper appreciation for the craftsmanship and philosophy behind every Atelier Z bass.

Atelier Z at Guitar Summit 2026
In September 2026, RockSo Music welcomed Atelier Z to Guitar Summit in Mannheim, Germany, where we presented a selection of their Japanese-made basses to European musicians.
Kokichi “Johnny” Motohashi and his son Akimitsu joined us throughout the three-day event, giving visitors a special opportunity to meet the people behind Atelier Z and experience their instruments firsthand.
It was a pleasure to see bass players exploring the instruments, trying different models and exchanging thoughts with the Atelier Z team.
For RockSo, Guitar Summit marked another chapter in our relationship with Atelier Z, following our visit to their workshop in Japan in 2024.
We continue to offer a carefully selected collection of Atelier Z basses at our shop in the Netherlands, where musicians are welcome to visit, compare models and experience the instruments in person.
