Japanese Hagi Ware

Hagi-yaki: the tea bowl that matures with time

Hagi-yaki (萩焼) comes from the city of Hagi in Yamaguchi Prefecture, at the far western end of the main island of Honshū, and is known above all for its chawan (tea bowls). A Japanese saying ranks tea bowls like this: "First Raku, second Hagi, third Karatsu." A new Hagi bowl at first seems reserved – a pale, shimmering glaze, a fine web of crackle, a simple unpainted form. Its real beauty only emerges through use.

Korean potters and the house of Mōri

The origins lie in Toyotomi Hideyoshi's Korean campaigns at the end of the 16th century. The feudal lord Mōri Terumoto brought two Korean potter brothers to Japan, who built the region's first official kiln near Hagi in 1604. One of them took the name Saka Kōraizaemon, which is still passed down today. In 1663 their pupil Miwa Kyūsetsu founded another kiln, from which the still important Miwa family of potters descends. The first Hagi chawan followed Korean bowls of the Joseon period, already highly prized by Japanese tea masters.

Clay, firing and glaze

Hagi-yaki uses a blend of several clays, the proportions varying from workshop to workshop. The main component is usually the light grey Daidō clay, discovered in 1717, supplemented by finer or more iron-rich clays such as Mitake or Mishima clay. The coarse, sandy material is fired in a chamber kiln on the hillside at about 1,180 to 1,340 degrees Celsius, for 14 to 40 hours depending on size. The slightly translucent glaze of feldspar and ash shrinks more than the clay on cooling – creating the fine crackle network called kannyū.

Hagi no nanabake: the seven transformations

Because glaze and body are porous, tea or sake slowly seeps through the fine cracks into the clay and darkens it over the years. This change is called Hagi no nanabake, "the seven transformations of Hagi" – not a fixed number of stages, but the observation that a well-used bowl keeps taking on a new face. Connoisseurs see this not as wear but as the true maturing of the piece in the spirit of wabi-sabi. Some collectors therefore dedicate a Hagi bowl to a single kind of tea.

The Miwa family and the 20th century

With the Meiji Restoration in 1868, the Hagi potters lost the protection of the Mōri house and had to survive as independent workshops. Artistic renewal came from the Miwa family: in the 1930s Miwa Kyūwa refined the glaze to a purer white, while his brother Miwa Jusetsu set new accents with powerful Oni-Hagi chawan of coarse, sandy clay. Both were named Living National Treasures, in 1970 and 1983 respectively.

How to recognize Hagi ware

Typical features are the soft, light body, a cream-white to beige glaze with pink shading and the fine crackle, together with an unglazed foot that shows the clay. Many chawan have a small notch in the foot ring called kirikodai; a common explanation sees it as a deliberate "flaw" that allowed pieces to be sold outside the lord's household. Among the glaze variants are Shiro-Hagi, pure white Hagi, and gohonte, with pale, often pinkish spots on a grey-beige ground. Our selection also includes darker interpretations in anthracite and grey-blue, with the reddish-brown body showing through at the edges.

Use: tea ceremony and sake

The Hagi chawan is made for matcha and only reveals its character when used. Hagi guinomi (sake cups) change in the same way through sake. Besides tea bowls, the Hagi tradition also includes vases, sake vessels and water jars for the tea ceremony. If you bring a bowl into everyday life rather than putting it in a display case, you can watch it mature over the years.

Care

Hagi has one of the softest bodies among tea ceramics. Soak a new bowl in lukewarm water for twenty to thirty minutes before first use, until no more air bubbles rise. Clean only with hot water and a soft sponge, without dish soap, which would seep into the clay, and never in the dishwasher. Let the piece dry completely upside down for one to three days before returning it to its cloth and wooden box, and never try to remove the brownish tint in the crackle.

What collectors look for

Many Hagi potters work in families that pass their craft down through generations; the signature and inscribed wooden box tell you about workshop and provenance. Older pieces may already show the first signs of nanabake – an asset for connoisseurs, not a flaw. Look at form, foot ring and glaze, and at whether the bowl sits well in the hand: with Hagi, it is ultimately use that decides its beauty.
