The Artist’s Final Mark
Japanese Rakkan Seals for Calligraphy and Art
A work of calligraphy is not complete when the brush is lifted. It is completed when the artist’s seal is placed. Designed for the balance, scale and spirit of your work, each KAMAKURA SIGNET rakkan is individually created and finished in our Kamakura atelier.
What Is a Rakkan Seal
A rakkan is the signature seal placed on a completed work of calligraphy, painting or other art. It identifies the artist, but it also forms part of the composition. Its size, position, shape and balance of red and white should support the work rather than compete with it.
A rakkan may contain your name, your art name, or a short phrase with personal meaning. In formal calligraphy, several seals may be used together. For many contemporary artists, one carefully designed seal is the natural place to begin.
A Tradition in the Tsukino Family
Our story began in 1898, when the first generation of the Tsukino family carved seals for a temple in Nara. Four generations later, we continue to create each artist’s final mark in Kamakura.
Mitsuhiro Tsukino is both a Zen monk and a nationally certified First-Class Seal Engraving Craftsman. His daily practice of zazen and calligraphy informs an approach based on restraint, balance and the considered use of empty space. Each design is made to belong to the artwork — not merely to sit beside it.
Today, Mitsuhiro designs the lettering and carries out the initial engraving. His wife, also a nationally certified First-Class Seal Engraving Craftsman, completes the final carving, test impression and finishing. Each seal passes through both pairs of hands before it leaves the atelier.
Choose What Your Seal Will Say
The right inscription depends on how you sign your work and how formal you want the seal to be. If you are unsure, tell us how you sign your artwork and let the master guide you.
Name seal
Your personal name, often used as a formal artist identification
Artists who sign with their personal name
Art name seal
Your personal name, often used as a formal artist identification
Calligraphers and artists with an established art name
Personal phrase or leisure seal
Your personal name, often used as a formal artist identification
A secondary seal or a more personal contemporary mark
Red Characters or White Characters
In a traditional pair, the name seal is often carved in hakubun and the art name seal in shubun. Contemporary artists may also choose one style according to the weight and atmosphere of the work. If you are uncertain, we will recommend the style that creates the better visual balance.
Shubun
The characters appear red against the paper

Hakubun

Rakkan Seals for Calligraphy & Art
Why the Traditional Shape Is Square
The square is the standard form for a formal name or art name seal. Its stable geometry gives the characters a clear frame and sits naturally within the vertical rhythm of calligraphy. Round and irregular seals are also used in painting, small works and leisure seals, but the square is the most versatile first choice.
Three Ways to Create Your Final Mark
Each material expresses a different relationship between the artist, the seal and the finished work. Japanese boxwood is our recommended standard. Kamakura-bori elevates the seal into a bespoke work of craft. Natural stone remains available for artists drawn to the classical tradition of seal carving.

Why We Recommend Japanese Boxwood
For generations, our family has arranged complex characters within the small end grain of wood. This experience allows us to create precise, balanced rakkan seals in Japanese boxwood, including very small seals for postcards and delicate work.
Boxwood is not presented as a substitute for stone. It is the material that most directly expresses our identity as Japanese seal engravers: controlled, durable and made to be used repeatedly over many years.
A Japanese Precedent in Wood Nakamura Randai
Wooden seals are not a modern substitute for stone. They also belong to the history of serious Japanese seal engraving. Nakamura Randai the First, one of the leading seal engravers of modern Japan, created seals in boxwood as well as other materials.
A pair of boxwood seals made by Randai for the Japanese painter Terasaki Kogyo is preserved in Japan’s Cultural Heritage Online database. The official record identifies the material as wood, specifically boxwood. This precedent shows that a wooden rakkan can carry both artistic authority and a distinctly Japanese approach to seal making.
KAMAKURA SIGNET continues this Japanese wooden seal tradition through the precise end grain engraving practiced by the Tsukino family since 1898.
Kamakura-bori The Masterpiece Line
Our highest rakkan line brings together two forms of carving: the seal face that completes the artwork and Kamakura-bori that transforms the body of the seal itself. Each piece is individually planned so that the carved decoration, lacquer finish and seal design form one coherent work.
Kamakura-bori rakkan seals are available in the complete size range: 12, 15, 18, 21, 24 and 30 mm. The pattern, finish, production time and price are confirmed through a personal consultation. This is not an added decoration to a standard seal, but a distinct work of Kamakura craft.
Choose the Right Size for Your Artwork
The correct size depends on more than the paper. We also consider whether the work is kanji or kana, the scale and strength of the brushwork, the amount of empty space, and whether one or several seals will be used. The guide below is a practical starting point.
12 mm — Postcards and small works
15 mm — Hanshi, shikishi and small works
18 mm — Medium works
21 mm — Hankiri and hanging scroll works
24 mm — Large works
30 mm — Extra-large works
Smaller and custom sizes are available upon request.

A Ritual in Four Steps
A rakkan is small, but it carries the artist’s identity every time it is pressed. We make each one with the same concentration given to the work it will complete.
1
Kanso 観想
Quiet Study
字入れ
Before the blade touches anything, there is silence. The master studies your name, your character, and how it should sit — finding the right balance and spacing the way stones are placed in a Zen garden.
2
Botto 没頭
Full Immersion
粗彫り
Cutting away the empty areas. Lost in the work, the master's bold, confident strokes give the seal its strength and life.
3
Seishin 整心
Calm Precision
仕上げ
The most exacting stage. A difference of just 0.1mm changes the dignity of the whole imprint. With a calm, steady mind and controlled breath, the master refines every line.
4
Zanshin 残心
Lasting Care
捺印
A Japanese idea meaning "the spirit that remains" even after an action is finished. The master's attention doesn't relax until the very first press of red ink onto paper — the moment your mark enters the world.
Frequently Asked Questions
Do I need an art name to order a rakkan seal
No. We can create a seal from your personal name, given name, initials, studio name or a short phrase. If you are unsure, choose Let the Master Guide You.
Should I choose shubun or hakubun
An art name is often carved in shubun and a personal name in hakubun. For a single contemporary seal, either may be appropriate. We will recommend the better balance for your work.
What size should I choose
Use the size guide as a starting point. If you send us a photograph and the dimensions of your artwork, we can recommend the most suitable size.
Is stone more authentic than wood
Stone is central to classical seal carving, while wood has long been used by Japanese seal engravers. Both are authentic. We recommend Japanese boxwood because it best expresses our workshop’s precision engraving heritage and is practical for regular use.
Can I order a round seal
Yes. Square is the standard first choice for a formal name or art name seal, but round and irregular forms are available by request.
Can I order two matching seals
Yes. A personal name seal in hakubun and an art name seal in shubun can be designed as a coordinated pair.
Can you create kanji for a non-Japanese name
Yes. Depending on the name and artistic intention, we can propose katakana, alphabet lettering or meaningful kanji. The final direction is confirmed before production.
