The Story of Akashiya

Akashiya was founded in 1716 in Nara, the city where Japanese brushmaking has been practiced for over a thousand years and which remains the country's main center for handmade fude (writing brushes). The workshop spent its first two centuries making traditional calligraphy and painting brushes (bristle bundled, glued, and shaped by a single artisan from start to finish), and that one-brush-one-maker discipline is still the standard for every piece in the line today.

Over the past century Akashiya has extended that craft into adjacent territory: the Sai brush pen series, fountain-pen-style brush pens with their own ink reservoirs, watercolor brush pens in traditional Japanese color sets, sumi-e and nihonga brushes for fine detail and broad strokes, and even makeup brushes. The common thread across all of them is the way the tip holds and releases ink, which is the part of brushmaking that takes the longest to learn and is hardest to mechanize.

What you are holding is a small piece of a 300-year continuous practice, made in the place where Japan's brush tradition began.
