Eboya Yatate Kaze Medium Fountain Pen
Eboya is the last Japanese workshop dedicated exclusively to the production of ebonite. Each fountain pen reflects a strong commitment to traditional craftsmanship backed by decades of technical know-how. Ebonite—one of the earliest industrial polymers—is made by vulcanizing natural rubber with sulfur (between 25% and 50%), and is valued for its durability, stability, and natural sheen. Engraved on the barrel, as on all Eboya pens, is Eboya Made in Tokyo, a clear mark of origin and authenticity.
This Kaze version—meaning wind in Japanese—features a deep blue-green tone developed exclusively for the bamboo models. It is not used on any other Eboya pen. Ideal for writers who want a distinctive everyday fountain pen, and for collectors looking for low-production pieces with a unique identity.
Concept and design
The name Yatate refers to a traditional Japanese portable inkwell used from the Kamakura period by samurai, and later in the Edo period by scholars and merchants. This modern interpretation keeps clean lines and balanced proportions where function leads the design. Hand-polished ebonite adds warmth and an organic feel that modern synthetic materials rarely replicate.
The Kaze color is exclusive to the bamboo models (Ricchiku and Yatate) and is not used on any other Eboya model. Its deep blue-green finish reinforces the idea of movement and flow, echoing wind as an invisible yet constant presence. The gold-toned metal clip adds an elegant, understated contrast while keeping the overall look balanced.
Functionality and filling system
Fitted with a 14K gold nib individually adjusted by the craftsmen at Nikko Ebonite Manufacturing, the Medium nib delivers a smooth, precise, and well-controlled writing experience. The pen uses an international cartridge or converter filling system, allowing compatibility with a wide range of fountain pen inks. To better appreciate the Medium size and its balance in hand, you can watch the official Eboya video here: watch on YouTube.
The precise assembly of every component, combined with the character of the ebonite, results in a fountain pen with remarkable quality and consistent performance from the very first stroke.
