What Is Amazake?
Amazake (甘酒, literally “sweet sake”) is a traditional Japanese fermented rice beverage with a thick, porridge-like consistency and natural sweetness. Despite its name, the most common variety contains no alcohol at all — the sweetness comes entirely from the natural breakdown of rice starch by koji mold enzymes.
Amazake at a Glance
- • Base: Steamed rice fermented with koji mold (or sake lees)
- • Alcohol: Zero (koji type) / Up to 1% (sake lees type)
- • Texture: Thick and porridge-like, sometimes strained smooth
- • Season: Traditional winter/New Year drink; now year-round
- • Temperature: Served hot in winter, chilled in summer
Amazake has been consumed in Japan since at least the Nara period (8th century). It was traditionally served at temples and shrines during festivals as a warming, nourishing drink for visitors — this tradition continues today, with amazake commonly offered free or at low cost at shrine hatsumode (New Year) events and summer festivals. It is classified as “drinking sweets” (nomu wagashi) in Japanese food culture.
The Two Types of Amazake
Koji Amazake (米麹甘酒)
Made by fermenting steamed rice with koji (Aspergillus oryzae mold) at around 55–60°C for 6–8 hours. The koji enzymes break down starch into glucose and maltose, creating natural sweetness without any added sugar. Contains zero alcohol.
- ✓ Non-alcoholic (safe for children, pregnant women)
- ✓ Rich in glucose, B vitamins, amino acids
- ✓ Thick, porridge-like texture with rice grains
- ✓ Milder, cleaner flavor — the “traditional” type
Sake Lees Amazake (酒粕甘酒)
Made by dissolving sake kasu (sake brewing by-product) in hot water with added sugar. Contains 1–8% residual alcohol depending on preparation. Has a more complex, slightly alcoholic character and thinner consistency.
- ✓ Rich in protein and amino acids from sake production
- ✓ Distinctive sake-adjacent flavor profile
- ✗ Contains alcohol — not for children or drivers
- ✗ Not appropriate during pregnancy
When buying bottled amazake at convenience stores or supermarkets, always check whether it is “米麹” (kome koji, non-alcoholic) or “酒粕” (sake lees, contains alcohol). The label will clearly indicate alcohol content. Most modern health-focused amazake products use the koji method.
Where to Drink Amazake in Japan
Shrine and Temple Events
The most atmospheric way to drink amazake in Japan. During hatsumode (New Year shrine visits, January 1–3), most major shrines offer free or ¥200–¥300 hot amazake to visitors. Setsubun events (February) and summer festivals often feature amazake stalls. Fushimi Inari Taisha (Kyoto), Meiji Jingu (Tokyo), and Narita-san Shinshoji Temple all serve amazake seasonally.
Specialty Amazake Cafés
A growing number of amazake specialty cafés have opened in Tokyo, Kyoto, and Osaka — serving amazake with seasonal toppings (kinako, yuzu zest, ginger, matcha), alongside wagashi. Nihombashi Amazake-an (Tokyo) and Amazake Alley (Kyoto's Ninenzaka) are popular destinations.
Convenience Stores and Supermarkets
Bottled amazake is widely available at every convenience store in Japan, particularly in winter. Morinaga, Kikkoman, and Hakkaisan brands offer quality packaged versions. Hot amazake dispensed from vending machines or convenience store hot drink sections is common from October to March.
Health Benefits of Amazake
Koji amazake is often called “drinkable IV drip” (nomu tenteki) in Japan due to its remarkably bioavailable nutrient profile:
- Glucose: Directly absorbed by the body without digestion — provides rapid energy. Traditional use during illness or after physical exertion.
- B Vitamins: Vitamin B1 (thiamine), B2 (riboflavin), B6, and B12 produced during koji fermentation — supports metabolism and energy production.
- Essential Amino Acids: Koji fermentation produces all essential amino acids the body cannot synthesize itself.
- Resistant Starch & Fiber: Supports gut microbiome health; the koji fermentation process produces prebiotic compounds.
- Ferulic Acid: An antioxidant compound found in rice bran, concentrated in fermented rice products — linked to anti-inflammatory properties.
Note: amazake is relatively high in calories due to its glucose content. It is nutritious but should be consumed in moderation as part of a balanced diet. Diabetics should consult a physician before consuming amazake regularly due to its rapid glucose absorption.
How to Make Koji Amazake at Home
Simple Home Method
Ingredients: 200g rice koji (乾燥米麹, available at Japanese grocery stores), 200g cooked rice, 400ml water
Step 1: Cook rice and let cool to about 60°C (140°F).
Step 2: Crumble rice koji into the warm rice. Add water and mix well.
Step 3: Keep the mixture at 55–60°C for 8–10 hours. Use a rice cooker on “keep warm” setting, a yogurt maker, or an insulated box.
Step 4: Stir every 2 hours. The mixture will become sweet as the koji enzymes break down starches.
Step 5: When pleasantly sweet (taste test), the amazake is ready. Blend smooth or serve with rice grains. Refrigerate up to 5 days.
Serve hot with a pinch of grated ginger (warming spice) or cold with yuzu zest in summer. Temperature is the critical factor — above 65°C kills the koji enzymes before fermentation completes; below 50°C encourages unwanted bacteria. A kitchen thermometer makes the process much more reliable.
