At the beginning of the 20th century, a unique artistic fusion emerged in Japan. As Western garden flowers – such as tulips, pansies, and roses – became increasingly popular in Japanese society, the master of woodblock printing, Tanigami Konan 谷上廣南 (1879–1928), captured this botanical invasion in a breathtaking way.
The “Pictorial Book of Western Flowers”
His masterpiece, Seiyō Sōka Zufu 西洋草花図譜 (Pictorial Book of Western Flowers), published around 1917, is a five-volume celebration of color. Unlike earlier botanical works that were often strictly scientific and medicinal, Konan’s woodblock prints are pure, unadulterated aesthetics. They were created for an audience that was beginning to fall in love with the exotic flora of the West.

Mastery of the Woodblock
Konan used the traditional Moku-hanga technique (multi-colored woodblock printing) to perfection. Each illustration is a “Nishiki‑e” – a “brocade picture” – where every single color requires its own hand-carved block. The results are images of incredible depth and luminosity. The way he layers the pigments gives the petals a velvet-like texture that a copperplate engraving could never achieve.
The Secret of Oyster Shells: The Radiance of Gofun
In the woodblock prints of Tanigami Konan – particularly in his masterpiece Seiyō Sōka Zufu (1917–1920) – there is a white that is more than just a color. It has a velvety, almost haptic texture that ordinary pigments cannot achieve. The secret behind this radiance is Gofun.
Art from the Sea
Gofun is a traditional Japanese pigment made from finely ground, weathered oyster shells. For centuries, it has been the “white gold” of Japanese art. To create it, the shells are aged for years before being crushed into a delicate powder and mixed with nikawa (animal hide glue).
A Tactile Experience
Unlike Western lead white, Gofun has a distinct physical presence. When applied to the woodblock, it creates a slightly raised surface. Konan used this to give white petals a three-dimensional quality. This “Oyster Shell White” reflects light in a soft, diffused way – lending the images a brilliance that feels almost alive.
It is this alchemy – the combination of the sea’s calcium, the forest’s wood, and the artist’s hand – that makes these works timeless treasures.
