Timeless Timber, Ageless Quality

Kozai refers to a class of timber, used in the construction of traditional Japanese Kominka (古民家) – which literally translates to old house.

Built prior to the second world war, with their distinctive thatched styled roof, the Kominka you’ll see in modern Japan were built up to 400 years ago- a testament to Japanese architecture and craftsmanship.

Be it a 400 year old beam cut from a 1,000 year old tree, or a complete frame of a house first built 200 years ago, our aim is to preserve this limited resource by redefining the purpose in which these materials are currently used.

About Kozai Timber

Kozai Timber is run by Will Beresford, Australian and 30 year resident of Japan.

Outside the snow season Will has been renovating buildings throughout Nagano and studying old Kominka under the guidance of his Japanese mentor (3rd generation builder) of 29 years.

Kozai Timber has an endless supply of this handpicked ancient lumber that is currently shipped directly to Australia, and is available to be shipped abroad.

Whether it’s used in Western, Japanese, or contemporary architecture, “Kozai” is a piece of history to take pride in your next build.
