The [IHADA Brass] architectural hardware changes in appearance as it ages becoming attached to the places and people who use them.

The brand [MATUREWARE by FUTAGAMI] is FUTAGAMI’s new brand for a line of architectural hardware products which started in February of 2015. The brand’s name is derived by replacing the word ‘hard’ in “hardware” with the word ‘mature,’ an ode to the naturally developing patina that occurs over the course of time, a characteristic of all FUTAGAMI products. MATUREWARE is produced with the intent that these architectural hardware pieces will grow with the people who use them and the spaces where they are installed.

FUTAGAMI Co., Ltd. / Manufacturer

“Futagami” is a brass foundry founded in the city of Takaoka in Toyama Prefecture in 1897, mainly manufacturing Buddhist altars and sculptural crafts such as lit lamps. In 2009, Oji Masanori (handicraft designer) rediscovered the beauty of IHADA (crude casting surface), which is the finish that comes from the process of sand casting, and launched the brand “FUTAGAMI” with a line of brass living ware. FUTAGAMI’s IHADA naturally develops a patina that occurs over the course of time resembling an aging/growing process which is also influenced by the place and people using them. This characteristic is expanded to a new line of products, in the architectural hardware brand [MATUREWARE by FUTAGAMI] which launched in 2015.
