The Story of Rice Shochu Nurtured in Hitoyoshi-Kuma, Kumamoto
Both sake and rice shochu are born from the same ingredient: rice. And yet, their flavors are strikingly different. Sake offers a clear, gentle sweetness, while rice shochu is known for its dry aroma and light, clean finish. The reason such distinct spirits can emerge from the same raw material lies in one added step: distillation. Sake is brewed; rice shochu is distilled. They begin in the same place, sharing the same pure rice and water, yet arrive at entirely different destinations. In that sense, sake and rice shochu are like siblings.
Kuma: The Home of Rice Shochu
One of Japan’s most celebrated regions for rice shochu is Hitoyoshi-Kuma, in southern Kumamoto Prefecture. Surrounded by the Kyushu Mountains and blessed with pure underground water and abundant rice fields, this area has been producing rice shochu for centuries.
The shochu made here is known as Kuma Shochu and is protected as a Geographical Indication under WTO agreements. It is a system similar to France’s AOC designation for wine: only products made in a designated region, with specified ingredients and methods, may bear the name. Kuma Shochu is, in every sense, a spirit inseparable from the land that created it.
Koji: Three Faces of the Same Rice
The flavor of rice shochu changes dramatically depending on the type of koji used.
Yellow koji, also used in sake brewing, creates a fragrant, refined, and delicate style. Black koji, used in Okinawan awamori, brings out deep richness and a full, aromatic character. White koji, which sits somewhere between the two, produces a clean, well-balanced profile and is widely used in rice shochu production today.
Even with the same rice, changing the koji reveals three entirely different expressions. Here, one finds the depth of Japan’s fermentation culture, where flavor is gracefully entrusted to the quiet work of microorganisms.
Another Layer of Craftsmanship
Building upon these foundations, many distilleries introduce their own subtle innovations. Some polish the rice to extreme degrees and prepare ginjo-style koji. Others use sake yeast and yellow koji, applying a three-stage fermentation process before long-term aging. Techniques refined over generations of sake brewing are now woven into the world of distilled spirits. Rice is a remarkably generous ingredient, one that continuously welcomes the imagination of its makers.
Warm It, and the Aroma Opens Further
Rice shochu also has a tradition of embracing temperature. It can be mixed with hot water or gently warmed. These serving styles bring out the roasted notes and underlying umami of the grain. Like warmed sake, it reflects a distinctly Japanese wisdom: letting temperature become an integral part of the flavor experience.
To Bangkok: Another Rice-Born Spirit
In Bangkok, awareness of sake has grown considerably. Rice shochu, however, despite sharing the same origin, is less frequently discussed.
“Beside sake, there is another spirit made from rice.” That perspective could offer a fresh entry point into Bangkok’s food culture. From the unique terroir of Kuma and the meticulous selection of koji to the intentional nuance of temperature, rice shochu offers a narrative waiting to be uncovered, layer by layer. (Mr. Bacchus)
