小山本家酒造
Koyama Honke Shuzo
A good day. A good sake. A good time.
Our story
He trained in Nada and Fushimi.
Then he found this water.
Founder Matabee Koyamaya learned his craft in the great brewing towns of Nada and Fushimi, then moved east and began brewing in Urawa in 1788. In 1808 he found fine water in Sashiogi, Saitama, and built his own brewery there — the start of a commitment to quality that continues today.
Saitama terroir
One spring.
One address.
Since 1808.
Pure natural water, sourced from the Chichibu mountains and drawn from 180m below the brewery, gives the sake a clean foundation. Koyama Honke brings that place into every bottle with rice-led flavour and poised balance.
Traditional wisdom. Modern precision.
Quality first, always.
Ginjo standards
Purposeful rice polishing and controlled low-temperature fermentation reveal a refined aroma, clarity and elegant balance.
180m spring water
Pure water drawn from deep below the brewery creates a clean foundation, soft texture and poised finish.
Human craft + precision
Skilled makers, laboratory checks and modern production systems work together under a simple principle: quality first.
More than two centuries of saying yes to quality.
A happy day or a hard one — Koyama Honke brews sake to be by your side, whatever kind of day it has been.
