Cup Sake Launched the Day the Tokyo Olympics Opened

Cup sake carries a reputation, and the reputation is train stations, vending machines and drinking alone. Some of that is earned. Most of it is out of date.

10 October 1964

That is the launch date, and it is not a coincidence. It is the day the Tokyo Olympics opened.

The idea came from Ozeki's tenth-generation president, Bunjiro Osabe, and it was blunt: make something you can drink straight out of the container, anywhere, without a set, without warming it, without a second piece of equipment. One go, 180ml, with a pull tab on top.

The slogan was anytime, anywhere, and the target was young people who were not attached to how sake had always been drunk. It worked. One Cup Ozeki has shipped somewhere around four and a half billion of them since.

Why 180ml Is the Right Number

One go is the traditional Japanese unit for a serving of sake, and it is what a tokkuri holds.

So the cup did not invent a portion. It took the portion that already existed and removed everything around it. That is a smaller idea than it looks and a much better one, because nothing about the drinking changed. Only the dishes did.

It is also, genuinely, the right amount. Enough to sit with. Not so much that you have committed to a bottle you now have to finish or waste.

The Reputation, and What Changed

For decades the format meant cheap sake, because cheap sake was what went into it. Convenience stores, kiosks, vending machines, shinkansen platforms next to an ekiben.

What has happened more recently is that serious breweries looked at a single-serve, sealed, well-portioned container and worked out there was no reason it had to hold bad sake. So now you get junmai, ginjo, even daiginjo in cups, and the artwork on the outside has become its own collecting hobby.

The format was never the problem. The contents were.

What We Pour

We keep a couple, and they are deliberately not the same kind of thing.

The Kaika Sanomaru is a tokubetsu junmai from the oldest brewery in Tochigi, with the city's mascot character on the cup. It is considerably better sake than the packaging is trying to suggest.

The Kikusui Perfect Snow is a nigori at 21%, which is high for anything undiluted, and it is Japan's best-selling nigori.

Why Order One Here

If you do not know sake yet, this is the cheapest possible way to find out what you like. You are not committing to a 720ml bottle on the strength of a description, and you are not asking somebody to explain a list to you first.

Open it, drink it, decide. Then order the thing you actually want.
