The three famous waters of Japan are the water of Hakkoda Sukayu in the Tohoku region, the water of the Yoro mountain range, and the water of the Tanzawa mountain range in the Kanto region, all playing crucial roles in Japanese sake brewing.
Sake breweries in Kanagawa use the rich groundwater from the Tanzawa mountains as their brewing water, with many locations even being selected for the Ministry of the Environment’s “Top 100 Famous Waters. This exceptional water is the foundation of Kanagawa’s premium sake.
Believing that good sake is made with good rice, Izumibashi is one of the few breweries in Japan that both polish and grow their own sake rice. Their proprietary junmai, crafted with attention to the unique properties of each rice field, benefits from this meticulous approach. At Izumibashi, they use a traditional tool called a kojibuta to make their koji. This traditional sake-brewing tool requires three times the effort compared to modern methods but allows for precise control over water volume and temperature, ensuring the highest quality. They produce their koji in small batches, each carefully tuned to the unique characteristics of the sake rice from each producer.
Kikkawa Jozo has been making sake since 1912 but in 2012 their brewmaster Masanori Mizuno took them in a radical new direction. Their Afuri sake is bold and brash, with lively flavors and prominent acidity. They draw well water from Mt. Afuri, an unusually mineral rich water source that allows for vigorous fermentation. Primarily low polish their rice is mostly milled to just 90% remaining allowing for the full flavor of the grain to come through. In addition they have revived older methods of developing acid making for bold and unusually tart sake perfect for food pairing.
Since 1872, Kumazawa Brewing Company, the only sake brewery in Shonan, Kanagawa, has been dedicated to crafting high-quality sake through a handcrafted, small-batch method that reflects the unique climate and character of the Shonan region. Their label, Tensei, offers “Song of the Sea,” which uses special Yeast Number 9, a sake yeast discovered in Kumamoto Prefecture that is ideal for ginjo sake, producing rich aromas and clear flavors. Additionally, “Infinite Summer” is made from “Gohyakumangoku” rice, sourced from Toyama and Shonan. The rice is polished to 60%, and Yeast Number 9 is used for fermentation. This rice imparts a juicy sweetness to the sake, which is bottled within 24 hours of pressing to preserve its delicate aroma and freshness.

The name of their sake label, “Tensei,” is inspired by an ancient Chinese proverb from the Five Dynasties period. An emperor of the Later Zhou Dynasty described the ideal color of celadon porcelain with the phrase “The rain has passed through the sky and the clouds have broken through” (雨過天青雲破処), referring to the clear, vivid blue of the sky after the rain, as the clouds begin to disperse. Inspired by this legendary hue, the brewery strives to create sake under the “Tensei” label that embodies the same refreshing clarity and richness.
To mark its 140th anniversary, Kumazawa Brewing Company is leading the “Sake Rice Project,” an initiative that bridges the region’s rich traditions with its future. Known for excellent rice cultivation since the Yayoi period, the area saw many rice fields abandoned due to post-war land reforms and agricultural policies that separated rice farming from sake brewing.
In response, the brewery has partnered with local farmers, listening to the land’s needs, and revived the tradition of making sake from locally grown rice. The aim is to produce sake unique to the region while preserving the beautiful rural landscape for future generations.
Today, 35% of the rice used in their sake comes from their own harvest, giving the sake a distinctive and unmatched quality. By maintaining consistent brewing practices, they aim to fully utilize the rice grown in this land.
As the sole sake brewery in Shonan, Kumazawa Brewing Company is committed to reclaiming abandoned farmland and continues to work towards producing sake with locally sourced rice. This effort is vital for supporting the community’s future, and the brewery is dedicated to pursuing this mission.
