In the world of Japanese traditional culture supported by washi paper, there are various types, but ganpi paper reigns at the pinnacle.
This paper, also called “the king of washi,” has been used for important documents and artistic works since ancient times due to its elegant texture and extraordinary durability.
Particularly, ganpi paper created using traditional techniques passed down in the Izumo region is highly valued both domestically and internationally.
This article introduces the charm and characteristics of ganpi paper, as well as its modern applications.
What is Ganpi Paper?
Among the various types of washi paper, ganpi paper stands as the most noble and can be considered the ultimate sheet that embodies the essence of Japanese culture. Its characteristics, backed by history and tradition, continue to captivate many people today as an art form that transcends the mere framework of paper.
History and Origin of Ganpi Paper
The history of ganpi paper is ancient, having been handed down for over 1,200 years, as evidenced by its inclusion in the Shosoin Imperial Repository. This paper, treasured by nobles and temples from the Nara to Heian periods, was refined alongside the development of Japanese culture and used for calligraphic arts and Buddhist scripture transcription.
In particular, Izumo ganpi paper, as a representative example of Izumo Folk Art Paper established through extensive research by Living National Treasure Eisaburo Abe, continues to be highly valued today.
Materials and Manufacturing Process of Ganpi Paper
The rarity of ganpi, the main raw material for ganpi paper, further enhances the paper’s value.
The main raw material for ganpi paper is wild ganpi that grows naturally in Shimane Prefecture. The ganpi fiber is extremely long and strong, which is the secret to the paper’s strength.
It is made using the traditional method called “board-drying,” where the paper is attached to wooden boards and dried in the sun, creating a unique texture. Through this labor-intensive process, a texture that can never be obtained with other washi papers is achieved.
Why Ganpi Paper is Highly Valued
Ganpi paper, which has been loved for centuries, has a charm that other papers do not possess.
The primary reason ganpi paper is valued is for its unparalleled quality.
It features a unique glossy surface and crisp paper body, a refinement that cannot be imitated by other papers. It also boasts high strength and durability, with approximately three times the strength of regular washi paper.
This allows works and writing to be preserved for generations. In cultural property preservation, ganpi paper is also valued for its excellent characteristics.
The Appeal of Ganpi Paper and Its Differences from Other Washi Papers
Ganpi paper, which has a special presence among washi papers, stands apart from other washi papers due to its unique characteristics. Understanding these differences will help you appreciate the true value of ganpi paper more deeply.
The appeal of ganpi paper, in a word, is “elegance.” The high-quality feel you experience when you hold it and the growing attachment as you use it will be an experience difficult to obtain with other papers.
Comparison Between Ganpi Paper and Other Washi Papers
The differences between the three major raw materials for washi paper bring individuality and different uses to each paper.
The three major raw materials for washi paper are kozo (paper mulberry), mitsumata (Oriental paperbush), and ganpi (Diplomorpha sikokiana), each with its own unique characteristics. Among them, ganpi paper is considered the most luxurious and has been used for special purposes.
Differences Between Ganpi Paper and Kozo Paper
Understanding the difference in characteristics between kozo paper, which is widely used in daily life, and ganpi paper, which shines in special settings.
While kozo paper is a representative of durable and practical washi paper, ganpi paper has a more delicate and elegant texture. Kozo paper is suitable for everyday use, whereas ganpi paper is often used for special works and documents.
Kozo fibers are relatively thick, whereas ganpi fibers are extremely thin and long, resulting in a dense paper with transparency.
Differences Between Ganpi Paper and Mitsumata Paper
While sharing a common trait in glossiness, there are differences in texture and strength.
Mitsumata paper is a beautiful washi paper with glossiness, but ganpi paper combines an even higher quality gloss with strength.
While mitsumata paper has a soft and warm texture, ganpi paper gives a sharper and more elegant impression.
Mitsumata can be cultivated, but ganpi is harvested from the wild, making it more rare and valuable.
The Beauty and Functionality Unique to Ganpi Paper
The appeal of ganpi paper lies not only in its beauty but also in its excellent functionality for practical use.
The greatest feature of ganpi paper is its exquisite texture, which combines a silk-like translucency that lets light through, a glossy surface, and a perfect balance of crispness and flexibility.
These characteristics allow it to accurately capture the movement of the brush and beautifully express the subtle gradations of ink.
It also excels in ink adhesion, allowing for clear reproduction of details in print works, thus expanding the possibilities for artistic expression.
Characteristics of Ganpi Paper
The characteristics of ganpi paper are evident not only in its visual beauty but also in its high practicality. These diverse properties enable its use in various applications.
Thinness and Transparency
The transparency of ganpi paper, which is delicate yet has a strong presence, enriches the expression of light and shadow.
A characteristic of ganpi paper is the beauty of its fibers visible when held up to the light. This delicate transparency is also prized for use in lamp shades and shoji paper.
The seemingly contradictory properties of thinness yet strength could be said to be the greatest appeal of ganpi paper.
High Durability and Preservation Quality
Ganpi paper, which increases in flavor with time, is ideal for valuable works and documents intended for long-term preservation.
Ganpi paper has surprisingly sturdy strength and durability, boasting about three times the strength of regular washi paper. Due to this characteristic, it is suitable for long-term preservation of important documents and art works, capable of maintaining its beauty over hundreds of years.
It is also resistant to insect damage and is highly valued in cultural property preservation.
Smooth Writing Experience
The surface of ganpi paper, which allows the pleasure of moving a brush or pen across it, inspires creative motivation.
The surface of ganpi paper is extremely smooth and uniform. When writing with a brush, ink, or pen, there is an exquisite balance between pleasant resistance and smoothness, allowing the writer’s intentions to be accurately expressed on the paper.
Writing a letter on this elegant ganpi paper naturally gives rise to heartfelt text.
Color Variations
You can choose between the type that preserves the natural texture and the white type with a pure impression, according to your needs.
Izumo ganpi paper comes in an unbleached type that preserves the natural texture and a white type that has undergone bleaching.
The unbleached type has a warm, natural color that increases in flavor over time.
The white type gives a pure and modern impression and has the effect of beautifully displaying the color of colored inks and paints.
Uses of Ganpi Paper

Calligraphy
Ganpi paper, which maximizes the beauty of ink gradation and lines, gives calligraphy works a special dignity.
As a calligraphy paper, ganpi paper has the characteristic of vividly expressing the delicate movements of the brush and beautifully showing the gradations of ink. It is particularly suitable for works requiring advanced techniques or those intended for display and preservation. With minimal bleeding, allowing the outlines of lines to be clearly expressed, it is also ideal for small script or seal script, where the expression of details is important.
Seal Carving and Printmaking
In seal carving and printmaking, which require expressive detail, the characteristics of ganpi paper greatly affect the quality of the work.
As a paper for seal carving, ganpi paper has an appropriate thickness and softness, with the characteristic of making the seal impression stand out clearly. In printmaking, it has the characteristic of good ink adhesion and faithful reproduction of fine lines and blurs. It is particularly suitable for techniques requiring precise expression, such as woodblock printing and copperplate printing.
