One in the morning, and the bar is still pouring. The room is low-lit, but you can read the label on the bottle. The bartender stays on his side of the counter. The music is quiet enough that the loudest thing in the room is ice.
None of that is only taste. Each of those three things sits just short of a line in the same Act, and the bar is on the side of every line that lets it still be open.
What the bar filed, and what it did not
Serving alcohol between midnight and six makes a venue a 「深夜における酒類提供飲食店 営業」 — a late-night alcohol-serving restaurant business — unless serving what the law treats as proper meals is its normal trade.
For that, the operator files a notification, not an application. Article 33 requires a notification to the public safety commission for each premises, giving the operator’s name and address, the name and location of the premises, and an outline of its structure and equipment. The Tokyo police publish the form. Nothing is granted here; something is declared.
This is the public-morals Act only. A bar also needs a restaurant licence under the food hygiene regime, which is a separate matter with separate concerns.
The three lines it must not cross
Cross any one of these and the same venue stops being a bar that notifies, and becomes a 「風俗営業」 — an amusement business — which needs a licence.
| Article 2(1) | The venue needs a licence if it |
|---|---|
| item 1 | provides 「接待」 while customers eat or drink |
| item 2 | operates at an interior light level of ten lux or less, measured by the method the National Public Safety Commission prescribes |
| item 3 | provides customer seating that is both difficult to see into and five square metres or less |
「接待」 has its own statutory definition, in Article 2(3): entertaining a customer in a manner that creates a convivial atmosphere. It is broader than it looks, and it turns on being hosted rather than on what is served.
Item 2 is the one that explains the room you are sitting in. Ten lux is dim. A working counter where someone is reading labels and measuring pours sits above it.
Why that decides the hour
Article 13 is where the distinction bites. A licensed amusement business may not trade between midnight and six in the morning. The prohibition attaches to the licensed category, not to alcohol.
There is a proviso, and it matters. A prefectural ordinance may permit trading after midnight, until an hour the ordinance sets, in areas the ordinance designates — and on particular days it defines for local customs. So this is a default with mapped exceptions, not an absolute.
Set against that, the bar serving you at two has, across most of the city, stayed on the notification side of all three lines. Its dimness has a floor, its seats are open to view, and nobody sits down with you. Not as a matter of taste: any one of those would put it in a category that had to close two hours ago.
The same logic covers the music. Letting customers 「遊興」 — be entertained — after midnight is a third category again, 「特定遊興飲食店営業」, and it needs a licence of its own. A late-night bar without one stays a place where you drink and talk.
The rule that turns away an 18-year-old
Article 32 applies most of the licensed-venue prohibitions to ordinary restaurant and bar operators, and for them the age rule is read as covering the hours from ten at night to six in the morning. Inside that window a bar may not admit anyone under 18 as a customer at all. Serving alcohol or tobacco to anyone under 20 is prohibited outright, at any hour.
That is a different rule from the one in the guide to smoking, which shuts under-20s out of a venue that is entirely a smoking room, whatever the time. Both can apply to the same bar on the same night, and they exclude different people.
What this page deliberately does not tell you
It does not say which venues hold which licence, and it gives you no way to work it out from the doorway. Ten lux is a measured figure, taken by a prescribed method, not something an eye can judge — a room can feel darker than it is. The categories above explain why late-night bars in Tokyo have the character they do; they are not a test you can run on a specific door.
This is a description of what the Act sets out. It is not legal advice, and nothing here is a judgement about any particular venue’s compliance.
Two of the things you cannot look up in advance are covered elsewhere: what a bar may add to your bill, and what it has to accept when you pay. The pattern by now is familiar. The durable answer is in the rule; the answer about the bar in front of you is at its door.
