Convenient Liquid Ink for Easy Writing

Liquid ink—often called bokuju—has been widely used since its invention in the mid-Meiji era.
Depending on the manufacturer, liquid ink may be classified as either glue-based or resin-based. These types differ in flow, gloss, drying speed, and suitability for different styles of calligraphy.

At Shoyu Online, we offer a variety of liquid sumi inks, from beginner-friendly options for children to high-grade inks for classical calligraphy, kana compositions, and kanji works—all at competitive prices. Please take a look and find the ink that best matches your writing style.

Try Various Inks and Enjoy Calligraphy

In recent years, liquid inks have evolved significantly. New formulations allow expressions closer to traditional solid ink (sumi sticks), while others reproduce the look of aged ink (koboku style). Trying different types of liquid ink can open up new creative possibilities and deepen your enjoyment of calligraphy.
