Sake: Japan’s National Drink
Sake — nihonshu in Japanese — is brewed rice wine with a history stretching back over 2,000 years. Unlike wine, which is produced by fermenting grape sugar directly, sake requires a two-stage process: first, koji mould converts rice starch into sugar; simultaneously, yeast ferments that sugar into alcohol. This parallel fermentation produces a drink of remarkable complexity — ranging from light and floral to rich and umami-dense — at alcohol levels typically between 14–18%.
How Sake is Classified
Japanese sake law defines quality grades based on the degree to which the rice grain is milled (seimaibuai — the percentage of the grain remaining after polishing):
- Junmai: Pure rice sake, no added alcohol. Full-bodied, often slightly acidic, pairs well with food.
- Honjozo: Small amount of distilled alcohol added — lightens the body and enhances aroma. An excellent entry point.
- Ginjo: Rice milled to 60% or less. Lighter, more aromatic, fruity notes.
- Daiginjo: Rice milled to 50% or less. The premium category — delicate, complex, often floral.
- Junmai Daiginjo: Pure rice, milled to 50% or less. The apex of the classification system.
Beyond classification, sake also varies by temperature serving style (warm/atsukan vs cold/reishu), filtration (muroka — unfiltered), carbonation (sparkling), freshness (nama — unpasteurised), and regional water character.
Major Sake Regions
Nada (Hyogo): The largest sake-producing district in Japan, known for strong, dry sake made with Miyamizu water from the Rokko mountains. The brands Hakutsuru, Kiku-Masamune, and Nada Gogo are based here.
Fushimi (Kyoto): Produces soft, slightly sweet sake using the gentle Fushimi spring water. Gekkeikan and Kizakura are the major names. The canal-side kura (breweries) of Fushimi Momoyama are a popular tourist area.
Niigata: Famous for tanrei karakuchi — clean, dry, light sake that pairs with the region’s seafood. Kubota and Hakkaisan are internationally recognised Niigata brands.
Akita, Yamagata, Fukushima: Tohoku produces some of Japan’s most celebrated sake, with breweries using pristine snowmelt water from mountain ranges.

Sake Bars and Tasting Events
Sake izakaya (nihonshu-specialising bars) in Tokyo, Osaka, and Kyoto offer curated lists of 30–150+ sake from small regional producers, with staff who can guide selections by region, style, and food pairing. Sake events — including the annual Sake and Shochu Makers’ Association tastings and regional festivals like Niigata’s Sake no Jin (March) — bring together dozens of breweries under one roof for ¥2,000–¥3,000 entry with unlimited tasting.
