《Characteristics》
Otani-yaki is one of the representative ceramics in Shikoku (Western Japan), originating in Oasa Town of Naruto City in Tokushima Prefecture 230 years ago.

In producing large-size ceramics, such as body hight-tall jars or water lily pots, "Ne-rokuro (literally, lying wheel)" method is used at forming, which is especially famous for its unique pair work - one forms the clay, while the other lying on the floor kicks the pottery wheel to rotate it. The Nobori-gama, (literally, climbing kiln) for firing them is said to be the largest kiln in Japan.

In recent years, from folk crafts to characteristic artworks, many ambitious works are created, which cherishes the warmth of rustic lifestyle kept from old times.

Materials Main raw materials are clay of Hagiwara, Sanuki and Himeda, and glaze made with Himeda clay, lime, wood ash, feldspar, silica and iron is used.
Crafting Processes [1] Crushing
Porcelain clay is crushed after drying. It usually takes one week for drying, but some types of product need more time.

[2] Filtering (Sifting)
Roughly crushed porcelain clay is sifted with sieve, and sort out to make large and small-sized pottery.

[3] Mixing
Water is added into the sifted fine clay.

[4] Wedging
Sifted clay is put into the wedging machine and mixed well with water.Then, required amount of clay is taken from the lump to make potteries of desired size. Forlarge ones, "Shino (string-shaped clay)" is made to form the products out of it

[5] Forming
Large products are formed using Keri-rokuro (literally,kicking wheel) or formed by a pair work called Ne-rokuro (literally, lying wheel) One of the craftsmen shapes the clay, while the other lies on the floor and kicks pottery wheel to rotate it.
Small products are formed using electric wheel.

[6] Drying
Products are dried in the shade for about 20 days, and then sundried.

[7] Glazing
Glazing is applied on half-dried products with a dipper. Products are uniformly soaked with ash glaze made from wood ash, bone ash, iron and manganese.

[8] Loading
Large products are put on shelf board one by one and all layers are stacked horizontally in the kiln.
Small products are put in spaces between large products or piled up on the shelf to optimize the productivity of the kiln.
Until all large and small products are loaded in Nobori-gama (literally, climbing kiln), it takes 1-2 weeks by 10 craftsmen.

[9] Firing
Products are fired at about 1,250℃ using firewood as a fuel. Firing process in Nobori-gama takes about 5-6 days and nights until complete baking, and in electric furnace or gas furnace, it takes about a whole day and night.

History In 1780 (late Edo period), a craftsman, whose name was Bun-emon, came to Bungo (now Oita Prefecture, Southern Japan) to make a pilgrimage to 88 temples in Shikoku. He made potteries with red clay of Kanigaya in Otani village. It is said that this was the start of Otani-yaki.

In Meiji period (19-20c), ceramic jars were mainly produced for indigo dyeing

In Taisho period (20c), the wartime boom and many changes of people's lifestyle affected the style of Otani-yaki.

And now, various products ranging from large ceramic jar to plate wares of daily use are being produced.
