FROM SCULPTURE TO WRITING: THE MULTIFACETED ART OF YOSHIKAZU TAKAI
Born in 1952 in Hyogo Prefecture, Japan, Yoshikazu Takai embodies an artistic metamorphosis that spans fields and generations. Initially famous as a sculptor, he expanded his influence into other areas of art and design.
Takai made a remarkable debut on the art scene with a solo exhibition in 1987 at the renowned Akiyama Gallery in Tokyo, marking the start of a distinguished career. Between 1987 and 1995, his successive exhibitions received praise both nationally and internationally. His large sculptures became landmarks in public spaces across Japan, adding a unique aesthetic touch to famous parks and squares.
However, change has always been a constant in Takai’s artistic approach. About ten years ago, he took an unexpected turn by focusing on the subtle world of stationery. This shift led to the creation of his stationery brand, "TETZBO".
By applying his unique artistic perspective, Takai developed stationery items that tell stories while encouraging individual creativity. Each "TETZBO" item carries the imprint of his sculptor’s background while exploring new artistic territories.
By making this bold change, Yoshikazu Takai demonstrated that artistic expression is not limited to a single medium. His transformation from a renowned sculptor to an inventive stationery creator illustrates his ability to reinvent himself while maintaining the emotional depth and complexity that characterize his work.
Today, he remains a lasting source of inspiration, affirming that a true artist is one who constantly evolves, continuously innovates, and always captivates.

Usage & Entretien

TETZBO EXPERTISE
What makes these pens unique
The work of the hand
Every manufacturing step is carried out by hand by Yoshikazu Takai. No industrial series, a gesture repeated piece after piece.
Le Chibien, metal pencil
The signature creation mimics a small freshly sharpened pencil, made of solid brass. Chibien means mini pencil.
Brass and iron
Unrefined base metals that darken and polish over time with handling.
No identical parts
Shapes, grooves, and finishes vary slightly from one piece to another. Your pen is truly one of a kind.
Repairable, rechargeable
The refills are standard Mitsubishi Jetstream references, and an Allen key is supplied with some models, such as the Chibien.
A master, a signature
Yoshikazu Takai makes it himself. Buying a TETZBO means receiving the work of a single pair of hands.
