The information exists.
It is only written in Japanese.

Standards, label rules and house customs in Japan are documented somewhere public — and almost never in English.

An editorial still life of Japanese bottle labels, travel documents and a quiet Tokyo bar

One document at a time

This desk takes a single published standard and explains what it actually requires, what it does not, and how to check a claim yourself.

The document, not a summary

Every claim names the statute, the article or the industry code it comes from, and links to it. You can check us.

The limits, stated

Where a rule is voluntary rather than law, that is the most important sentence on the page — so it is written down, not implied.

A visible review date

Regulation moves. Each page carries the date its claims were last checked against the source, and the sources are monitored weekly.

Sake

Reading a Japanese sake label

Junmai, ginjo and daiginjo have exact production requirements. Read the rice-polishing number, ingredients and designation without turning them into a quality ranking.

Whisky

Reading a Japanese whisky label

What the words on the bottle establish, and what they are permitted to leave out. Sourced to the Liquor Tax Act, the National Tax Agency and the industry code.

Tokyo

What a Tokyo bar may do

Charges, smoking, payment, licensing hours. The rules that decide what happens to you at the door and on the bill, none of which are published in English.

Worked example

The small print, one line at a time

Every bottle carries a boxed block on the back. It looks like an ingredient panel. It is a tax declaration, and the difference is worth money to you.

01 / 06

製造者 Manufacturer

The company liable for the tax. Not, on its own, evidence of who distilled the spirit — those can be different companies, and the label is not required to say so.

02 / 06

製造所所在地 Address of the production site

Where the bottling or blending was carried out. A Japanese address here does not establish that anything in the bottle was distilled in Japan.

03 / 06

内容量 Volume

The one figure on the panel that means exactly what it appears to mean.

04 / 06

品目 Tax category

A tax word, not a quality word. The category permits a bottle in which nine parts in ten are added neutral alcohol.

05 / 06

アルコール分 Alcohol content

Required. Note what is not required alongside it: nothing about maturation, cask or origin.

06 / 06

And that is the whole list

Alcoholic drinks are exempt from the ingredient, allergen and origin declarations that food carries. A producer may add them. None has to — so their absence tells you nothing at all.

The reference

Every term on the bottle, in one place

A thirteen-page reference that does what a 700-word page cannot: the full label vocabulary, term by term, with what each one establishes and what it never does.
