Eboya Hakobune Kunpuu Leafy Wind Small Fountain Pen
The Eboya Hakobune Kunpuu Leafy Wind Small Fountain Pen pairs green and black Japanese ebonite with a compact 128 mm clipless profile. Its warm surface, manageable proportions and 14K gold nib create a comfortable, balanced writing instrument for regular use. It is particularly suited to writers looking for a distinctive Japanese fountain pen without the width or visual weight of a larger model.
The Hakobune form
Hakobune (方舟) refers to an ark or vessel. Eboya associates the name with the wish that its fountain pens will carry happiness to their owners. The model expresses this idea through a traditional barrel shape with gently tapered ends and flat finials. Its clipless construction keeps the outline calm and uninterrupted while leaving the ebonite fully visible.
Kunpuu Leafy Wind ebonite
Kunpuu (薫風) is the green ebonite finish that Eboya calls Leafy Wind. The name suggests a fresh breeze passing through foliage at the beginning of summer. Green tones flow beside deep, almost black areas, giving the material a sense of movement and depth as the pen turns in the light.
Every barrel and cap is made from a different section of marbled ebonite. The proportion of green, the direction of the veins and the darker areas therefore vary naturally from one pen to another. This individual pattern is an essential part of the Kunpuu finish rather than a manufacturing irregularity. The discreet Eboya Made in Tokyo engraving identifies the origin of the pen.
Compact proportions for everyday writing
The Small version measures 128 mm when closed, with a diameter of 12.4 mm across both the barrel and cap. It offers a slim, manageable alternative to the larger Hakobune sizes while retaining a reassuring presence in the hand. The format works well for everyday notes, correspondence and longer writing sessions.
Ebonite feels naturally warm and comfortable to hold. Without a clip or heavy decorative trim, the design remains visually restrained and allows the green and black marbling to define the character of the pen from every angle.
Gold nib and international filling system
The Eboya Hakobune Kunpuu Leafy Wind Small Fountain Pen is fitted with a 14K gold nib for a controlled and balanced writing experience. Its compact body provides a natural grip without making the pen feel insubstantial, making it suitable for both brief annotations and extended use.
It accepts standard international cartridges and converters, allowing the user to choose between convenient cartridges and the broader selection of colours available in bottled ink. The Inktraveler presentation includes one compatible converter and one ink cartridge.

Caring for ebonite
Avoid prolonged exposure to direct sunlight, high temperatures or excessive humidity. When the fountain pen is not in use, keep it clean and dry inside its case, preferably in a dark place. A gentle wipe with a clean, soft cloth is sufficient for routine exterior care; abrasive cleaners and solvents should not be used.
Before storing the pen for an extended period, remove the cartridge or converter and rinse the section with water at room temperature. Allow every component to dry completely before reassembly, and never force the cap or filling system into place. Eboya advises against using pigment inks. Gradual changes in colour or gloss are natural characteristics of ebonite and should not be considered defects.
Frequently asked questions
What does Kunpuu Leafy Wind mean?
Kunpuu (薫風) is the Japanese name of Eboya’s green finish. The maker uses the English expression Leafy Wind to evoke a fresh early-summer breeze moving through leaves.
Do all Kunpuu fountain pens have the same pattern?
No. The balance and direction of the green and darker areas vary throughout every ebonite rod, giving each pen its own marbled pattern.
How compact is the Small version?
It measures 128 mm when closed and 12.4 mm across both the barrel and cap. It is the compact option within the Hakobune family.
Which filling system does it use?
It accepts standard international cartridges and converters. This Inktraveler presentation includes one converter and one ink cartridge.
Does the Hakobune have a clip?
No. The clipless construction is a deliberate part of the design and preserves the model’s clean, continuous outline.
Eboya and Japanese ebonite
Eboya is the writing-instrument brand of Nikko Ebonite Manufacturing, a Japanese company established in 1952 and recognised as the country’s only remaining ebonite manufacturer. Its expertise covers the production of ebonite rods, the development of coloured mixtures and the work required to turn the material into durable writing instruments.
The company began offering its own fountain pens under the Eboya name in 2009. Bringing material production and penmaking together keeps both stages connected to the same craft tradition. The Hakobune Kunpuu Leafy Wind reflects that approach through a restrained shape and a green pattern that belongs to one pen alone.
