Eboya Ricchiku Kaze Wind Green Medium Fountain Pen
The Eboya Ricchiku Kaze Wind Green Medium Fountain Pen transforms the shape and visual flexibility of bamboo into a Japanese ebonite writing instrument. Its blue-green and black marbled body, clipless silhouette and 14K gold nib create a distinctive yet balanced design. It is ideal for writers seeking a comfortable handcrafted fountain pen with a pattern that is unique to every piece.
Concept and Design
The name Ricchiku (立竹) means “standing bamboo”. Eboya shaped the model to express the beauty, strength and flexibility of a bamboo stalk growing towards the sky. The raised sections along the body recall its natural nodes, while the absence of a clip preserves a sleek and continuous silhouette. The discreet Eboya Made in Tokyo engraving confirms its origin.
The Kaze finish—meaning “wind” in Japanese—is officially classified by Eboya as Bluegreen. It combines blue-green marbling with a black base, creating visual depth and movement reminiscent of bamboo swaying in the wind. The pattern develops irregularly: some pens display a greater proportion of black, while others reveal stronger green or blue tones.
Each body is made from the original colored ebonite developed by Nikko Ebonite Manufacturing, ensuring that no two pens look exactly alike. The material-forming process may also create distinctive patterns on the top of the cap, including small stars, spirals or irregular shapes. The body can display concentric and undulating lines reminiscent of the growth rings found in wood.
Functionality and Filling System
The Ricchiku Kaze Wind Green Medium is fitted with a carefully tuned 14K gold nib designed to provide smooth, precise and controlled writing. Its 15 mm diameter offers a stable grip, while the Medium size provides a substantial presence in the hand without reaching the larger proportions of the Ricchiku Large.
The filling system accepts both international standard cartridges and converters, compatible with brands such as Pelikan and Rotring (not compatible with Montblanc, Waterman or Caran d’Ache). Each body is individually hand-turned and polished in Tokyo. The careful assembly of all its components, together with the color of the ebonite, results in a writing instrument of remarkable beauty and quality.

Care and Maintenance
To preserve the color and natural luster of the ebonite, avoid prolonged exposure to direct sunlight, heat and humidity. Store the pen in a dark place and occasionally wipe its surface with a soft cloth. If the pen will not be used for an extended period, remove the ink and flush the filling system thoroughly with water.
Before changing ink color or manufacturer, clean the section and feed with water until no ink residue remains. Eboya specifically advises against using pigment inks in its fountain pens.
Frequently Asked Questions
What does Ricchiku mean?
Ricchiku means “standing bamboo”. The body of the fountain pen visually reproduces a bamboo stalk and its characteristic raised nodes.
What does the Kaze finish mean?
Kaze means “wind” in Japanese. Eboya classifies the color as Bluegreen, a marbled combination of blue-green and black inspired by bamboo moving in the wind.
Does every pen have the same marbled pattern?
No. The balance of black, green and blue, as well as the distribution of the streaks, varies between individual bodies. These differences are a natural characteristic of marbled ebonite.
Does the Eboya Ricchiku have a clip?
No. The clip is deliberately omitted to preserve the clean, continuous silhouette of a bamboo stalk.
Which filling system does it use?
The pen accepts international standard cartridges and converters. The presentation includes one converter and one ink cartridge.
Can pigment inks be used in this fountain pen?
No. Eboya specifically advises against using pigment inks in its fountain pens.
Brand History and Philosophy
Eboya is the writing instrument brand of Nikko Ebonite Manufacturing, a Tokyo company established in 1952 and recognized as Japan’s only remaining ebonite manufacturer. Ebonite is produced by combining and vulcanizing natural rubber with sulfur, creating a durable material with a warm feel and a characteristic luster developed through careful polishing.
In 2008, Nikko Ebonite succeeded in developing its own colored and marbled ebonite varieties. One year later, it opened the Eboya shop and began selling its original fountain pens. The Ricchiku reflects this combination of technical knowledge and Japanese design sensitivity: a nature-inspired instrument whose shape, texture and color are defined by the way the material is formed and finished.
“Like a bamboo stalk moving in the wind, the Ricchiku Kaze brings strength, flexibility and serenity to every written word.”
