Collection: Vermilion Sumi Ink (Shu Ink)

SHUBOKU

Vermilion — A Color That Has Enriched Japanese Culture Since the Tenpyō Era

In ancient Japan, vermilion—known as tan—was treasured for its brilliance and symbolic power. As noted in the Manyoshu, the vivid vermilion used on the pillars of Heijo-kyo and Tenpyō-era temples served both decorative and protective purposes, making it one of the most valued pigments of the time.

In the late Muromachi period, vermilion was introduced to Hakata in Kyushu. Because of its rarity, mining and sales were strictly controlled, and private production was prohibited. Only after the Tokugawa Shogunate authorized its manufacture in 1609 did vermilion ink (Shuboku) begin to be produced. The use of vermilion for corrections and seals became common during the Meiji era.

From Pigment-Based Vermilion to Genuine Mercury Vermilion

High-quality vermilion ink is made using refined mercury, creating a vivid, lustrous red that maintains its beauty over time. More affordable types use pigment-based substitutes, which may fade with age.

For artists seeking the finest quality, we recommend mercury-based vermilion (honshu). These inks are noticeably heavier due to their mercury content, making weight a useful clue when comparing inks of similar size.

Our collection ranges from accessible pigment-based vermilion inks in various hues to top-grade professional formulations, allowing you to select the perfect vermilion for calligraphy, seals, corrections, or artwork.
