The site will also be home to a state-of-the-art brewing and distilling research and teaching centre.
Managing director Gerald Michaluk said: “It may not at first appear there is a connection between Dreghorn and Japan, but there is.
“In Japan you will find a small piece of Scotland in the form of a church which once graced Dreghorn but which was dismantled and rebuilt in Tokyo.
“As well as the sake brewery, which will almost exclusively export its sake to Japan, there will be our research and development centre and a brewing and distilling training school, subject of course to licensing.
“We have been making sake on a very small, almost domestic, scale and are now ready to build a sizable facility.”
The Arran Brewery is applying for planning permission for the site, which used to house Dreghorn’s primary school. It hopes to be producing sake by this winter.
The company is raising funds for this and other projects through a “crowd funding” initiative which closes on April 4.
