Tsuji Honten - in Katsuyama town, Okayama, Japan - was founded in 1804 by the Tsuji family. Today's brother & sister team, Soichiro & Maiko Tsuji, are the seventh generation brewers (Maiko-san is one of the few female toji in Japan!) The brewery originally brewed sake for the Miura family: local lords who governed Katsuyama. There are currently nine members of the team, which is why Tsuji Honten's brands are Gozenshu, meaning 'sake for gentlemen' and Gozenshu 9.

It is Tsuji Honten's aim to produce sake with both taste and clarity. They are pioneers of using omachi rice and an ancient, medieval brewing technique: bodaimoto.

'Rocky Mountain', 'Misty Mountain' and 'Mountain Stream' are all brewed using this ancient method first developed by monks during the Kamakura Period (1185-1333). The bodaimoto method produces sake with rich, deep, slightly sour and umami flavours.
