Asahara Shuzo is a family brewery located in Saïtama Prefecture, in the heart of the hills that precede the Chichibu mountains, northwest of Tokyo. It was founded in 1882 by Zenjiro Asahara when he was only 29 years old. Today Kenichi Asahara runs the factory, he is the representative of the 5th generation.

The locality of Saïtama is a relatively new terroir in the production of sake and does not enjoy the same reputation as other more "classic" regions. A recent story that has prompted Asahara Shuzo to innovate a lot to gain attention. Today, it offers products with a strong character, worn by two very young Toji in their thirties. Dynamic brewers and, above all, trained directly by Kenichi Asahara, a master in the art of handling yeasts.
