The Japanese Silk Road
Oya stone is not only about building stone walls or granaries any more.
So what are the popular uses of this great resource?
I had the pleasure to talk with Shizukazu Sakamoto, head of Barnstone Co., Ltd., who processes the stone.
“Oya has more than 20 companies in the stone industry. Regardless of where you look, it is quite common for companies to sell Oya stones as thin boards to use in the house.
I often get orders for TV backboards and Kitchen back walls.
Being a porous wall and having cavities it can also help with balancing the humidity. Zeolite in the stone has a deodorizing effect and is sometimes used in hospitals and bathroom walls.
The stone boards being thin helps to keep the price more reasonable.
If you are living in Utsunomiya you have subsidies available for Oya stone installation for private residences and stores, it is definitely worth doing some reading about.”
