It’s a Japanese sake handbook to easily learn about Japanese sake. This handbook was produced for a Japanese sake seminar intended for people who work at restaurants and bars. The seminar was held in New York by Iinumahonke, a sake brewery located in Shisui, Chiba Prefecture. The handbook helps local restaurant owners and employees understand Japanese sake in more detail. Not only that, the pocked-sized design makes it easy for them to keep it close at hand and tell other people about the charm of sake.
