LIXIL's Face Bricks Used for Preservation and Restoration of Tokyo
Station's Landmark Red Brick Building
LIXIL recreated the color and condition of historical face bricks using original
manufacturing techniques.
Tokyo, Japan (October 3, 2012) -- Japanese housing equipment and building materials manufacturer
LIXIL Corporation (Head Office: Chiyoda, Tokyo; President and CEO: Yoshiaki Fujimori) is engaged

in the construction project to preserve and restore Tokyo Station's Marunouchi-side Building,which is designated as an Important Cultural Property by the Japanese government(Construction project owner: East Japan Railway Company). LIXIL successfully recreated historic
face bricks*1 used on the landmark Tokyo Station's landmark building (known as the Red BrickBuilding). LIXIL's face bricks are used on the outside walls of the 3rd floor, including the domed
roofs at the north and south ends of the building, all of which were destroyed during World War II(Approx. 400 thousand face bricks were used).

*1: Face bricks and exterior wall tiles: Often used for brick buildings constructed during the Meiji-Taisho era in Japan(from late 19th century to early 20th century). Face bricks are thin bricks placed on the structural brick walls to decorate
them. In later times, "tiles" installed on reinforced concrete structure buildings became popular construction materials.
Since the manufacturing method and usage of face bricks and tiles are same, "tile" has been used to describe bothmaterials since 1922.

In 1914, Tokyo Station's Marunouchi-side Building was constructed based on the design by arenowned Japanese architect Kingo Tatsuno. The Red Brick Building is a classic Meiji-Taisho era
Western style building. With domes at the north and south ends of the building, its imposing figure
has been a symbol of the gateway to Japan’s capital city, Tokyo. During the war in 1945, theoriginal station building lost its 3rd floor, including the domes at the north and south ends, thereby
becoming the 2-story building which many Japanese people are familiar with.
Making full use of its extensive expertise and knowledge in ceramic production, LIXIL took on thechallenge of producing red face bricks that would aesthetically harmonize with the original facebricks on the 1st and 2nd floors of the station building. LIXIL selected to partner with Akai Tile Co.,
Ltd. a Japanese tile manufacturer (Head Office: Tokoname, Aichi; President: Yuji Akai) for thisproject. LIXIL and Akai Tile have collaborated on many projects to restore various historicbuildings in the past. The test production for this project started in 2003. LIXIL and Akai began thefull scale production of the face bricks in 2010 after 7 years of trial and error. Over 15,000 facebricks were manufactured during the trial production phase of this large project.
LIXIL will continue to actively participate in tile restoration projects so as to protect and preserve
Japan’s valuable architectural heritage for the next generation.

Tokyo Station Marunouchi Station Building Face Brick Restoration
The red face bricks decorating the exterior walls of the Marunouchi Station Building are thesymbol of Tokyo Station, the entrance to Japan’s capital. When the building was originallyconstructed, five manufacturers took part in the production of the face bricks. Color tones of thered face bricks inevitably varied due to differences in the raw materials and kiln temperatures
used during production. Today’s modern ceramic technology makes it difficult to recreate thecolor variances caused by turn-of-the-century production. The authentic recreation of suchproduction conditions proved the greatest challenge in this project.
In order to reproduce the exterior of Tokyo Station as it was 100 years ago, LIXIL spent sevenyears in repeated trials to achieve aesthetic harmonization between the new face bricks andthose of the original construction.
1. The Greatest Challenge: Recreation of Distinctive Color and Subtle Color Variation(1) Reproduction of the Original Red Brick Color・Securing Raw Materials
In the early stage of the project, a decision was made to use the red soil of Japan's Chita
Peninsula, the same material used as the main ingredient of the face bricks at the time of thestation building's construction. However, it was expected that the difference in the location andtiming of mining would result in differences in chemical composition of the soil leading toconsiderable variation of color. This meant that even if test production was approved,difficulties could be encountered in reproducing the same color during the full-scale production.
To prevent such a problem, the 100 tons of the red soil required for full-scale production was
secured before test production commenced.
・Arranging Production Condition of the Kiln
The required "bright red color" cannot be recreated using modern-day firing temperatures(1,200 to 1,250 degrees Celsius). The same kiln temperature used at the time of the original
station building construction (1,000 to 1,100 degrees Celsius) needed to be replicated. Akai
Tile, an experienced restorer of historic tiles, made a courageous commitment to dedicate oneof their production kilns to this project in order to meet this challenge.
(2) Recreation of Color "Variation"
The color variation of face bricks at the time of the original station building's construction was
the inevitable result of many factors involved in the face brick production such as; the mining of
raw materials, kiln firing temperatures, and conditions in the manufacturing plants., Accordingto the records of the original construction, even though strict standards were applied to facebrick production in order to achieve color uniformity, the acceptance rate was a mere 40%.
Now color uniformity is far more manageable thanks to the vastly advanced modern kilntechnology. However, this project required production conditions to be controlled so that colorvariation was intentionally created. This was an enormous challenge. Firing conditions andraw material formulas were repeatedly adjusted and tested. The color tones of all the trial
samples were measured (colorimetrically analyzed) and recorded. Over 50 conditions weretested and approximately 100 samples were produced for each of those conditions. To
prepare for full-scale production, large lot production was also tested. Ultimately, 15,000
samples were produced before the production conditions were finalized.

2. After Completion of Full-Scale Production
After the decision was made to start the full-scale production in 2010, the color tones weremeasured again at the project site which confirmed conditions for full-scale production. Based on
the results, it was decided to use three different conditions for the face brick production and mix
placement of the face bricks on the exterior walls of the station. It was also decided to produce
face bricks for corner areas combining manual production with normal production processes.
Approximately 400,000 tiles were produced during the full scale production from late 2010 toearly 2011. Although the full-scale production was completed within 2 weeks, it was the result of7-years of testing and trial production.
