In 1873, Wahei Kimura created his sake which he named Kamotsuru, giving birth to a brewery that officially became a company in 1918. Producing exceptional sake requires not only high-quality water, but also perfect mastery of rice polishing. At the end of the 19th century, this step was limited by grindstones driven by water mills. The Satake company revolutionized the process in 1898 by inventing Japan's first rice polishing machine, achieving an unprecedented polishing rate of 75%. This advancement paved the way for sakes of exceptional finesse. From 1970 to 1988, Kamotsuru wins the gold medal at the National New Sake Competition for 18 consecutive years, dedicating the quality of its vintages. In April 2014, during an official dinner between Shinzo Abe and Barack Obama, it is a Kamotsuru sake that is chosen to be served, an honor that further establishes the reputation of this historic Hiroshima house.
