The tradition of brewing sake in wooden barrels is a prominent feature in the Japanese sake culture. Determined to maintain the culture of wooden barrel brewing for the next 100 years, Imayo Tsukasa Sake Brewery commissioned craftsmen to build new wooden barrels, and employees of the brewery took active part in their production as well. The sake brewed in those barrels has been named HITO TO KI – Japanese words meaning human, wood and moment. Through this design, Bullet Inc wanted to encourage the viewer to touch and feel the product rather than read and understand the information on it.
