Health benefits make sustainability more meaningful

How Shikkui and Limix help create healthier indoor environment

Harmful pathogens (bacteria, viruses, mold spores), VOC gases, bad smells and house dust continuously circulate in any indoor air, originating from a variety of sources: dirt, skin cells, furniture, paint, wallpaper, pets, and any objects we use indoors.

The natural antimicrobial feature of Shikkui and Limix disinfects the air from microbes, and its high porosity not only helps bring indoor humidity to a comfortable level of 40-60% (recommended by ASHRAE), but also in combination with photocatalyst targets VOC gases breaking them down into harmless compounds. In addition, Shikkui surface being anti-static prevents dust accumulation, thus serving as anti-allergic.

History

  • Birth of Japanese Shikkui6th century (Asuka period)

    Lime plasters were first introduced to Japan from mainland Asia in the 6th century, following the spread of Buddhism. From that time, the lime plasters in Japan continued to develop and evolve independently based on the locally available resources. That is when Shikkui - the Japanese lime plaster was born and started to develop in its unique way.

  • Seaweed in ShikkuiSengoku period (16th century)

    The discovery of using seaweed as water retention agent and usage of plant fibers to reinforce Shikkui brought a boom in castle construction throughout the 16th century, during Sengoku period in Japan, when the country was in its civil war period for several decades. Shikkui as a finish coat provided a durable plaster coating of the castle walls, which was critical in times of wars, and protected the walls from rain erosion.

  • Shikkui still a luxuryEdo period (17th century)

    With the start of the Edo period renaissance, as the united country entered its famous non-military and culture transformation period. With common housing structures still mostly made of wood and sometimes earthen plasters, Shikkui still remained a special luxury finish layer over earthen plasters allowed only to the nobles, upper samurai society.

  • Great fire of MeirekiMarch 2, 1657

    With the growth of population and the spread of wooden housing highly concentrated in Edo (now Tokyo) region, the cases of fire spreading quickly from building to building became very frequent. The infamous Great fire of Meireki destroyed 60-70% of the Japanese capital and killed over 100,000 people. As a result, the Tokugawa Shogunate allowed Shikkui as finish layer to protect buildings from fire for everyone, not just the nobles. Since that moment, Shikkui started to spread all across Japan for both residential housing and commercial construction, especially merchant warehouses had thicker layer of Shikkui to protect the commodities from fire damage.

  • New aesthetic sideLate Edo period (18-19th centuries)

    The aesthetic side of Shikkui finishes also further developed in Edo period, with the boost in craftsmanship, application techniques and tools. With the exterior Shikkui applications serving as protection and aesthetic purposes, the interior Shikkui coated earthen wall provided both aesthetic and health benefits, enhancing air quality with its anti-bacterial and air cleaning properties, as well as durability.

  • Main finish coatingsMeiji period (19th century)

    During the Meiji period in the 19th century and the reforms in the social structures it brought, Shikkui finishes were also used on western brick constructions in modern design, remaining the main finish coatings once again. Many cultural buildings during that period, which are now classified as national and world heritage, were also mostly finished with Shikkui.

  • Tagawa Sangyo established1924

    Tagawa Sangyo established by Shichiro Yukihira in the city of Tagawa, Fukuoka prefecture, the region famous for its highly pure limestone deposits.

  • First commercial Shikkui in Japan1975

    Tagawa Sangyo launched the very first premixed commercial Shikkui lime plaster in Japan called Shirokabe. Shirokabe is still the best-selling traditional Shikkui product in Japan.

  • Limix as tile version of Shikkui2003

    While developing a panel-type Shikkui, Tagawa Sangyo applied “geo-mimicry” and created Limix - the tiles made of Shikkui and compressed with extremely high pressure (4,000 tons), without any heating process or binders.

  • Further innovations2010’s

    Development of modern Shikkui finishes, including decorative artisan products, sprayable and roller-applied paint-type Shikkui, highly humidity-regulating finishes, DIY Shikkui finishes.

  • Current and future development2020’s

    Continuous innovations and improvements of natural Shikkui technologies, with even stronger focus on respiratory health and the environment.
