Sake and drinking in Japan
Sake grades follow rice polishing and added alcohol. The drinking age is 20 and the duty-free limit is three bottles of about 760 ml.
Sake grades turn on two things: how far the rice is polished and whether alcohol is added. Junmai means rice, koji and water only, while ginjo and daiginjo mean 60% or less and 50% or less of the grain left. The drinking age is 20, and each adult can bring in three bottles of about 760 ml duty-free. Drinking outdoors is not illegal nationally, though JNTO advises against street drinking.
| Topic | Rule | Basis |
|---|---|---|
| Drinking age | 20 | Ministry of Justice |
| Duty-free limit | 3 bottles of about 760 ml per adult | Japan Customs |
| Public drinking | Not illegal nationally | JNTO |
| Whisky standard | Voluntary since 2021 | Industry association |
How do sake grades work?
The Japan Sake and Shochu Makers Association sorts sake into special-designation sake (tokutei meisho-shu) and regular sake (futsu-shu). The grade names below belong to the special-designation group. The figure is the share of the rice grain left after polishing, so a lower number means more polishing.
| Grade | Rice left | Notes |
|---|---|---|
| Junmai daiginjo | 50% or less | No added alcohol; koji rice 15% or more |
| Daiginjo | 50% or less | Added alcohol allowed; koji rice 15% or more |
| Junmai ginjo | 60% or less | No added alcohol; low-temperature fermentation |
| Ginjo | 60% or less | Added alcohol allowed; low-temperature fermentation |
| Tokubetsu junmai | 60% or less, or a special method | No added alcohol |
| Tokubetsu honjozo | 60% or less, or a special method | Added alcohol allowed |
| Honjozo | 70% or less | Brewer's alcohol up to 10% of the polished rice weight |
| Junmai | No minimum | Rice, koji and water only |
Junmai in a name means no added alcohol. Junmai on its own has no polishing minimum, so the word alone says nothing about how far the rice was polished.
How old do you have to be to drink?
You must be 20. Adulthood fell to 18 on 1 April 2022, but the limit for drinking and smoking stayed at 20, per the Ministry of Justice. The duty-free alcohol allowance below does not apply to anyone under 20. Rules on minors in bars and the drink-driving limit were not found.
How much alcohol can you bring in duty-free?
Each adult can bring in three bottles of about 760 ml each without duty, per Japan Customs. Duty-free alcohol is also exempt from liquor tax.
This is the allowance for bringing alcohol into Japan. The limit for taking sake home is set by your home country and is not covered here. A customs page also gives duty rates for amounts above the allowance, but it carries no year, so no rate is shown here.
Can you drink in public?
Yes, nationally, but drink where it is normal. JNTO’s local laws page says drinking outdoors is not illegal, that hanami picnics are normal, and that you should keep calm.
Another JNTO page, on travelling mindfully, advises against drinking on the street or outside convenience stores, which it says may bring police attention or fines. The two pages differ in tone. Read together: it is legal, so drink at a picnic or in a venue and skip the street and the front of a convenience store. Local bylaws vary: news reports (secondary) described a Shibuya ward ordinance banning drinking in streets and parks from 18:00 to 05:00 since 1 October 2024, without a fine, and its 2026 status is unclear right now. Follow any posted signs.
Before you go Keep outdoor drinking to hanami-style picnics and stay calm. Skip the street and the front of convenience stores.
How do you pour and drink with others?
Pour for others, not yourself. JNTO’s food etiquette guide gives the table rules:
- Pour for the people around you and hold your glass while it is poured.
- An empty glass signals that you want a refill.
- Leaving a drink unfinished is fine.
At an izakaya, a small otoshi dish arrives automatically and is charged as a table fee. JNTO says it is not free and you cannot choose or swap it. Ordering food in Japan covers otoshi, booking and the rest of the table manners.
What are shochu and awamori?
Honkaku shochu is single-distilled shochu made by a traditional method from natural ingredients, per the association’s shochu basics page. Okinawa’s version is awamori. The legal definitions of kou-rui and otsu-rui shochu were not found.
Awamori holds the geographical indication Ryukyu, per the National Tax Agency. It uses rice koji made with black koji (Aspergillus luchuensis) and a pot still. Awamori aged 3 years or more is called kusu. The techniques arrived more than 500 years ago.
Is Japanese whisky legally defined?
Only by a voluntary industry standard. The Japan Spirits and Liqueurs Makers Association set it in February 2021, and it has been fully in force since April 2024. It requires:
- Saccharifying, fermenting and distilling in Japan.
- A distillate under 95% alcohol by volume.
- At least 3 years in wooden casks of 700 litres or less, in Japan.
Caramel colour is allowed. The standard binds association members only, so a producer outside the association is not bound by it and the standard is not a guarantee on every bottle. Press reports say a logo was adopted in March 2025 and that a geographical-indication application to the National Tax Agency was planned for early 2026. The result is unclear right now.
To verify The rules come from a Japanese-language news summary and a Suntory page, not the official standard. Read the association’s own text before you quote them.
Can you visit a distillery or brewery?
Two visits have confirmed details. Nikka’s Yoichi distillery in Hokkaido runs a free guided tour of about 70 minutes, for 1 to 9 people, by reservation only, and walk-ins are refused. The distillery is closed 23 December to 7 January. Check Nikka’s page for current rules.
The Gekkeikan Okura Sake Museum in Fushimi, Kyoto, is open about 9:30 to 16:30 and closed at Obon and New Year, per a Fushimi sake guide page. Admission is $2 (¥300), souvenir included (medium confidence); older pages show $3 (¥400) and $4 (¥600), so confirm before you go.
Dollar figures use about ¥155 to US$1 and are rounded; you pay in yen, so check the rate.
Hakushu prices and dates and brewery visits in Nada and Niigata were not found. The Food guide gives the last known Yamazaki details.
Where next?

Halal and kosher in Japan covers mirin and cooking sake, and Eating vegetarian and vegan in Japan covers dashi. For alcohol before an onsen bath, read Onsen etiquette.
