The ROOZENITH is the signature monometal of back-to-back Japan National Champion Kohei Nishimura, built as a pure expression of precision, control, and refined competitive performance.
Drawing heavily from Kohei’s signature bimetal, the Zetica, the ROOZENITH carries over nearly identical size, weight, and shape to preserve the crisp responsiveness and effortless control that define his playstyle. Every movement feels sharp and deliberate, delivering the kind of direct feedback that lets advanced players push technical precision to its highest level.
The ROOZENITH embraces monometal simplicity as both a design philosophy and performance advantage. Without relying on added rim weight, its exceptional balance and stability are achieved entirely through careful shaping and weight distribution. The result is a remarkably pure playing experience that highlights accuracy, timing, and player input with incredible clarity.
The ZETICA is Kohei Nishimura’s third signature bimetal from Japan Technology, built to meet the demands of back-to-back Japan National Champion level competition play.
Designed as the next evolution beyond the Teseract, the ZETICA features an even wider profile to improve consistency on large movement tricks while delivering the precise control needed for technical execution in every direction. It is a competition focused design engineered to handle speed, dynamic movement, and technical complexity at the highest level.
Every element of the ZETICA was developed to match Kohei’s exacting standards. Its powerful bimetal construction delivers exceptional stability and rotational force, while its refined weight distribution creates a level of control that feels sharp, deliberate, and highly responsive in play.
