The sake brand name, "Tama no Hikari," which is also the brewery's name, comes from the "Tama" of Kumano Hayatama Shrine in Kishu, to which the first generation Nakaya Rokuzaemon revered, and the "Hikari" (light) of Amaterasu Omikami, the child of the principal deities Izanagi-no-Mikoto and Izanami-no-Mikoto. It is said that the name was bestowed upon the brewery by the chief priest with the wish that the sake would "shine brightly, reflecting the light of the divine spirit." For the sake rice, they use carefully selected sake rice varieties that they source directly, including Yamada Nishiki, Omachi from Okayama, and Iwai from Kyoto. They carefully mill the rice in-house using a flat milling method to avoid damaging the white core of the rice, pursuing the best possible flavor from the rice. For the brewing water, they use groundwater flowing through the Momoyama hills, resulting in mellow-tasting junmai ginjo and junmai daiginjo. It is recommended as a sake to enjoy with meals, as it enhances the flavor of a wide range of dishes. While it can be enjoyed chilled, you can further appreciate the richness of the rice by serving it lukewarm or warm. The current logo is inspired by the "diamond ring" that appears when light returns to the world after a total solar eclipse. It embodies the desire to be an indispensable presence that illuminates daily life like the sun.
