Oya Stone is a natural tuff formed from volcanic ash 15-20 million years ago. Quarried in Oya Town (Utsunomiya, Japan), it features a soft green hue called "Green Tuff," created by its unique mineral content. Heat & Fire Resistance Oya Stone is heat- and fire-resistant, ideal for pizza ovens, coasters, trivets, and candle holders. Air Clean & Humidity Control Great for interiors, fridges, or shoe boxes-naturally purifies air, reduces odors, and balances humidity. Healing & Relaxing Effects Oya Stone contains zeolite, which emits negative ions and far-infrared rays—said to support cell health, immunity, relaxation, and balance. As a Natural Building Material Oya Stone has unique patterns with black specks called "miso," created from volcanic ash. Each piece is one of a kind, perfect for art and architecture. It regulates temperature and provides excellent acoustics-once used as natural refrigerators, today reborn as cafés, galleries, and studios.
