Naorai created a new form of sake by distilling it without heat, allowing the flavor of the sake to remain intact. To represent the depth and tranquility of Japanese culture, "shide" (paper streamers) are used to help connote a sacred area. To express the beauty of the sake, Nosigner traced the shape of a water-filled balloon created by surface tension and connoted the moment when purified water droplets drop.

Naorai, a visionary brand in the Japanese sake industry, originates from the remote island of Sankaku, home to around 30 residents. The brand's journey began with the conception of "MIKADO LEMON," a unique sparkling lemon liquor. Operating in a shrinking Japanese sake market, Naorai has consistently sought to find a unique purpose that only they could fulfill. Committed to preserving and passing down the diverse and rich culture of Japanese sake, which has flourished in over 1200 breweries across Japan, Naorai focuses on the harmonious coexistence of human activities with nature, flora, fauna, and microorganisms. This inspiration stems from their learning at the Lemon Garden on Sankaku Island. Naorai strives to redefine the regional strengths of various areas through sake, adopting a perspective that focuses on their virtues. Their dedication to creating sake is meticulous, emphasizing quality ingredients, traditional brewing methods, and flavor, with the goal of producing beverages that enhance both physical and mental well-being. The brand values transcending time and space, endeavoring to honor and continue traditions. Naorai envisions a future where like-minded individuals come together, share a drink, and engage in "Naorai," a slow, deliberate journey towards realizing their shared dream. Naorai's story and history evolve over time, symbolizing their commitment to "brewing" time and societal connections through their sake.
