KOCHI Plaster
Plaster
Kochi plaster has been highly praised in Japan for its whiteness, beauty, and durability. Its raw material is high-quality limestone mined from the mountains of Kochi, which are part of the Shikoku mountain range, and has been used as a plaster material in many buildings since ancient times. The limestone in this region is highly pure and contains few impurities, so when it is processed into plaster, its whiteness and smoothness stand out. As a result, Kochi plaster has a high reputation as the "white of Japan."
History
Looking back at the historical background, Kochi's history and culture, including the late Edo period patriot Sakamoto Ryoma, have contributed greatly to the spread of plaster culture. In particular, Kochi plaster, which has been used to repair and reinforce historical buildings such as Kochi Castle, plays an important role as a material that supports traditional Japanese architecture. For this reason, Kochi plaster goes beyond being a simple building material and has a special presence that is deeply connected to the history and culture of the region.

Five characteristics of Jomon Plaster
01. Health benefits
Plaster has antibacterial, antifungal and bactericidal properties due to its strong alkaline properties, inactivating 99.99% of viruses and bacteria such as coronavirus and influenza viruses, and preventing sick house syndrome, allergies and asthma.
It purifies the air and creates a healthy indoor environment. It is VOC-free, so it is safe for people with chemical sensitivity. It also improves immunity, self-healing ability and sleep quality
The fermentation action increases the number of good bacteria that promote health in the room, improving immunity, self-healing ability, and sleep quality.
02. Comfort
The humidity control effect keeps the humidity constant, providing a comfortable living environment throughout the four seasons. In winter, it warms you from the core of your body, and in summer, it creates a cool space. The purifying effect removes pet odors and other odors. The porous structure absorbs sound and the soundproofing effect creates a quiet and comfortable space.
03. Sustainability
CO₂ emissions during the plaster manufacturing process are neutralized by the CO₂ absorption of plaster walls, making it a sustainable building material that contributes to environmental conservation and the prevention of global warming. Humidity control and insulation effects reduce heating and cooling costs and electrical energy costs.
Harmony between nature and humans, made from 100% natural materials, it has a low environmental impact and a long lifespan, reducing running costs.
04. Psychological effects
The natural texture and color of Jomon plaster has a calming effect, and the warm aesthetics of this natural material provide a space of peace and healing. It creates a "purity" throughout the space, refreshing the mind and body. It provides a sense of tranquility, relaxation, and increased concentration.
The humidity-regulating effect creates a cool space in summer and a warm space in winter, so physical comfort leads to a psychological sense of security, which calms emotions, frees the mind, and promotes positive thinking.
05. Social contributions
Direct contribution to preventing global warming and protecting the global environment.
Zero environmental impact when disposed of, sustainable job creation, reduction of health damage, promotion of environmental education, social infrastructure that is resilient to natural disasters, and plays a part in global measures against global warming and protecting the global environment.
