Tachibana Yasukuni

Tachibana Yasukuni (橘保国, 1717-1792) was an Osaka-based painter and book illustrator of the mid-Edo period, best remembered as the son and artistic heir of Tachibana Morikuni (1679-1748), the prolific Kano-school illustrator whose woodblock-printed picture books, or ehon, helped define the genre for eighteenth-century Japan. Yasukuni was born into a household that was already deeply embedded in the commercial book trade of Kamigata, the Kyoto-Osaka cultural region, and his career carried forward his father's project of translating the brushwork and compositional repertoire of Kano painting into the more democratic, broadly disseminated medium of the printed pattern book.

Morikuni had studied with Tsuruzawa Tanzan, a Kano-school painter in Kyoto, before settling in Osaka and devoting his career to producing illustrated books that brought Kano motifs, brush techniques, and compositional models to a wide audience of artisans, amateur painters, and connoisseurs. His landmark works, including Ehon shahō bukuro (1720), Unpitsu sōga (1749), and Ehon tsūhō shi (1729), circulated widely and served as essential reference texts for two generations of Japanese craftsmen and painters. When Morikuni died in 1748, Yasukuni inherited both the studio and the publishing relationships that supported it.

Yasukuni's most important original contribution to the ehon tradition was Ehon noyamagusa (絵本野山草, Picture Book of Mountain and Field Plants), first published in 1755 in five volumes from the Osaka publishing house. The book is a botanical compendium organized around the four seasons, presenting Japanese flora — peonies, hydrangeas, lotuses, irises, chrysanthemums, daffodils, vines, grasses, and dozens of other species — through woodblock illustrations that combined the observational accuracy of Edo natural-history drawing with the calligraphic line and atmospheric composition of Kano painting. The work was reprinted multiple times during the eighteenth and nineteenth centuries and became one of the most influential Japanese botanical reference books of its era, supplying pattern motifs for textile designers, ceramic painters, lacquer artists, and later generations of ukiyo-e printmakers.

In addition to Ehon noyamagusa, Yasukuni produced or contributed illustrations to several other Kamigata ehon, continuing the Tachibana family practice of organizing pictorial reference material around themes — flowers and plants, birds and animals, human figures and occupations — that could serve both as aesthetic appreciation and as practical models for other artisans. His style maintained the Kano-school grounding of his father's work, with confident brush-derived line work and balanced spatial compositions, while exhibiting a slightly softer, more naturalistic treatment of botanical subjects that reflected the broader eighteenth-century interest in honzōgaku (natural history studies) and the importation of Chinese and Dutch botanical illustration conventions through Nagasaki.

Yasukuni died in 1792 at the age of seventy-five. He represents an important transitional figure in eighteenth-century Japanese visual culture: an Osaka professional who carried forward the Kano tradition through the printed book, who participated in the rising eighteenth-century interest in scientific botanical observation, and whose Ehon noyamagusa continued to circulate as a practical reference text well into the late nineteenth century. Surviving copies of his books are held by the Library of Congress, the Metropolitan Museum of Art, the British Museum, the Art Institute of Chicago, and major Japanese institutional collections.
