The walls of the Imperial Hotel were adorned with rare yellow scratch face bricks, produced at the Imperial Hotel's brick manufacturing factory in Tokoname. Hatsunojo Ina and his son Chozaburo were invited as technical advisors and, following trial and error by skilled craftsmen, four million bricks and tens of thousands of intricate terracotta pieces were produced, perfectly shaped to meet Wright's specific requirements. Following the completion of the hotel, Ina took on the equipment and the workers of this factory, creating the foundation of Ina Seito (INAX).

Inside the hotel, ornamental perforations enriched the light and shadow of the interior as sunlight filtered in from the skylights and windows. Wright's calculated use of light combined with scratch faced bricks, carved Oya stones, and intricately designed terracotta produced attractive silhouettes, creating a unique and majestic aesthetic experience.

Terracotta Decorations

Following the Great Kanto Earthquake in 1923, new large buildings such as department stores, banks, and government agencies were rebuilt with reinforced concrete and covered with ceramics. These buildings, embellished with flamboyant decorative terracotta, symbolized the recovery of Tokyo.

The trend of decorative buildings quickly spread to other major cities. Decor from various parts of the world was adopted in the designs of ornamental terracotta, and Japanese customs such as symbols of the owner were often also included in the designs.

Equipped with the knowledge gained producing terracotta pieces for the Imperial Hotel, Ina Seito (INAX) became one of the leading terracotta manufacturers in Japan.

Earthenware Pipes Key to Japan's Modernization

  • Before becoming involved in the production of bricks and terracotta for the Imperial Hotel, Hatsunojo Ina started an earthenware pipe manufacturing business in 1902 and operated a mass-production factory in Tokoname.

  • While pipes were produced in various parts of Japan, those produced in Tokoname and by Ina Seito (INAX) were known for their high quality and used in major cities such as Tokyo, Yokohama, Nagoya, Osaka, and Kobe.

Steel rods and rails recycled from rail-tracks were placed around the great kiln to support and protect the brickwork from the expansion and contraction caused by the change in temperature of the kiln.

The great kiln with a 21m-tall chimney built in 1921 still stands today at the INAX MUSEUMS in Tokoname. The kiln was coal-fired from 14 furnace openings placed evenly on both sides. Due to its extensive size, it took three to four days to fire and 10 days to cool down the kiln. Large pipes with a diameter of 90cm along with other products such as clinker tiles were produced in this kiln during its 50 years of operation. The kiln and the chimney are designated as registered tangible cultural properties of Japan.

When firing this kiln, salt was inserted with coal at high temperatures to render vitreous coating on the products to make them waterproof. The walls of the kiln chamber are still shiny from the salt glaze that built up over time.
