The name "Tenka no Shisei" comes from the phrase "Only the most holy man in the world can be wise and intelligent..." (Chapter 31) in "The Doctrine of the Mean," said to have been written by Confucius' grandson Zisi. "Tenka no Shisei" means a holy person with the highest virtue, and in China, a holy person sometimes refers to sake. From this, "Tenka no Shisei" was chosen to convey the meaning of the best sake that can rival the heavens. "Kiwami Hijiri Junmai Daiginjo Tenka no Shisei" is a sake made with Omachi rice with a polishing ratio of 20%. Omachi rice, the root of sake rice, is large and has a large spherical core, so existing rice polishing technology could only polish it to around 38% at best. However, by using a newly developed state-of-the-art rice polishing machine and improved Omachi rice, they took on the challenge of polishing to the limit and succeeded in polishing the rice to 20% of its original size. This was the first attempt in the world to do this with Omachi rice, and all of the proteins and lipids that cause unpleasant flavors have been removed, resulting in a sake with a new flavor.
