Kiln Plaza and Museum (Downdraft Square Kiln)

What the Kiln Plaza and Museum (Downdraft Square Kiln) Is

The Kiln Plaza and Museum (Downdraft Square Kiln) (窯のある広場・資料館（倒焔式角窯）, Kama no Aru Hiroba Shiryōkan) is a brick downdraft kiln of 1921 and the two-story timber building that shelters it, in Okuei-cho, Tokoname City, Aichi Prefecture, entered on Japan's register of Tangible Cultural Properties on 12 June 1997. The shed is tiled, has two floors and covers 373 square meters of ground.

A downdraft kiln works against gravity before it works with it. Flames rise off the fireboxes to the crown of the chamber, turn downward, pass through the stacked wares and exit into a flue beneath the floor. Heat therefore circulates instead of escaping straight up the stack, which suits thick, heavy pieces that need long, even firing. This particular kiln is fired from both sides, so the wall of brick facing you carries a row of stoke holes rather than a single opening.

What came out of it was drainpipe. Tokoname supplied clay pipe for the water and sewer systems that Japan laid down as it industrialized, and this workshop is thought to have specialized in the largest sizes made in the town, roughly 90 centimeters in inner diameter. Shochu bottles and clinker tile were fired here as well. Production stopped in 1971.

The building reopened as a museum in 1986. Inax, which had just changed its corporate name from Ina Seito, restored the kiln, the shed and the chimney to mark the occasion. Everything that is now the INAX Live Museum grew outward from this one structure.

Why It Is on the National Register

Registration is the lighter of the two systems Japan uses for built heritage, aimed at buildings and structures of the past century and a half that give their surroundings a recognizable character. The Kiln Plaza and Museum (Downdraft Square Kiln) went onto the register under the criterion for structures contributing to the historic landscape of the country, and it carries registration number 23-0006.

Tokoname has fired clay since the medieval period, but the industry that built the modern town was not teaware. As demand for drainage and conduit pipe grew, square kilns and brick chimneys multiplied across the hillsides. Most were pulled down after the economic boom years. Kilns preserved in the open air survive in several places; a kiln still standing inside the workshop built around it is a good deal rarer, and that combination is what the register recognizes here.

The brick chimney on the same site is registered separately, as number 23-0007. The two are physically one system, joined by an underground flue, but the register classifies one as a building and the other as a structure of another kind, so they appear as two entries.

In November 2007 the kiln and the chimney were together recognized by the Ministry of Economy, Trade and Industry as part of Japan's modern industrial heritage.

What to Look For

Visitors walk into the firing chamber. Decades of stoking left their record on the brick, and the surface inside reads quite differently from the tidy exterior. Standing in the middle of it gives you the volume of the thing in a way no photograph manages.

A projection-mapped sequence plays on those walls, putting flame colour and the movements of the kiln crew back into the empty chamber.

Then look up. The roof trusses of the shed are exposed above the plaster walls, heavy timber posts and beams meeting overhead, so that wood, white plaster and brick all sit in the same field of view. The black-painted exterior was standard for Tokoname factory buildings, and the museum has kept it.

Conservation work ran for three years starting in 2016, and the Kiln Plaza and Museum (Downdraft Square Kiln) reopened in October 2019. The owner set out to hand the century-old fabric on for another fifty or hundred years, and the team went as far as matching the texture of the wall finish and the roof tiles.

The displays around the kiln include the wooden forms, presses and hand tools of the pipe trade, along with photographs of the town at its industrial peak. Part of a tunnel kiln 80 meters long, which ran in an Inax plant until 2005, has been re-erected in the same hall. Seeing the two side by side lays out the shift in ceramic manufacturing from firing one batch at a time to firing continuously.

Visiting the Kiln Plaza and Museum

The Kiln Plaza and Museum is open as one of the exhibition halls of the INAX Live Museum, and the interior can be walked through freely. Doors open at 10:00 and close at 17:00, with last admission at 16:30. The museum closes on Wednesdays, except when a public holiday falls on one, and over the New Year period. Since the main reception desk sits inside this building, arriving visitors buy their tickets here before anything else.

One ticket covers every hall on the site: 1,000 yen for adults, 800 yen for university students, 500 yen for junior and senior high school students, 250 yen for elementary school pupils and 900 yen for visitors aged 70 and over. Preschool children enter free, as do holders of a disability certificate together with one carer. Cash, credit cards, electronic money and code payments are all accepted.

Photography is allowed, and the owner encourages visitors to post their pictures on social media. Tripods, monopods, selfie sticks and flash are not permitted in the exhibition rooms, and shooting for magazines, broadcast or any commercial purpose needs advance clearance.

The nearest station is Tokoname on the Meitetsu Tokoname Line. Change there to a Chita Bus and get off at INAX Live Museum-mae, two minutes on foot. Walkers coming through the Pottery Footpath district should allow a 20-minute walk after the Tokoname Ceramic Hall, or a 15-minute walk after the Tōei climbing kiln. Drivers reach the site in roughly seven minutes off the Tokoname interchange, and parking for 80 cars is free.

Prices and hours change. The figures above were checked on 30 August 2026, so confirm them on the official site before you travel.
