Founded in London by Gow Tanaka in 2020, 3RD/DIADEM brings Japanese sensibility to contemporary objects.
We work with a compressed paper composite developed for high-end interiors: light in the hand, strong in daily use, resistant to water and heat. Every piece is made in East London, combining digital precision with hand finishing.
Our approach draws on Karesansui principles, clarity, balance, restraint, so the form can speak for itself.
