The Vending Machine Guide for Runners in Japan

There's a moment every visiting runner has. You're 6K into a run somewhere in Tokyo, it's hotter than you planned for, and there — glowing on a residential street corner at 6:40 in the morning — is a vending machine.

Japan's vending machines are the country's most underrated running infrastructure. They're everywhere, they're stocked, they work, and half of them will sell you a hot drink in winter. But the labels are mostly in Japanese and the choices are genuinely confusing. Here's what to press.

The three sports drinks, decoded

Pocari Sweat (blue and white) — The classic. Mild, slightly sweet, closest to a light isotonic drink. The unfortunate name is a translation artifact; it tastes nothing like its name suggests. This is the default correct answer for a hot run.

There's also Pocari Sweat Ion Water (lighter blue label) — same idea, less sugar, less sweet. If regular Pocari feels syrupy to you, this is the one.

Aquarius (usually a lighter blue/silver can or bottle) — Coca-Cola's competitor. Slightly more citrus, a bit lighter. Genuinely a matter of taste; runners here have strong opinions and there's no wrong answer.

OS-1 (white bottle with blue) — This one is different and worth knowing about. It's an oral rehydration solution, sold as a quasi-drug for actual dehydration and heatstroke, with much higher sodium and much less sugar. It tastes noticeably salty and not very pleasant.

Don't drink OS-1 casually — it's not a sports drink. But if you've badly overcooked a summer run and feel genuinely unwell, this is the thing to buy. You'll often find it in drugstores more reliably than vending machines.

What else is worth pressing

• Mugicha (barley tea) — unsweetened, caffeine-free, cold, and deeply refreshing. The most Japanese hydration choice there is.
• Water — obviously. Look for 水 or "Water"; usually the cheapest button.
• Green tea (お茶) — unsweetened by default in Japan. Do not expect the sweetened iced tea you may know from home.
• Hot drinks in winter — red buttons/labels mean hot (あたたかい). A hot corn soup or hot lemon after a cold January run along the Tama River is a small, perfect thing.

One warning: unsweetened is the norm here. If you want something sweet, you have to choose it deliberately — which is generally good news for runners.

What it costs

Most bottles run ¥130–180. Some machines, especially in residential neighborhoods and near stations, run cheaper — you'll spot ¥100 machines and occasionally ¥90. Prices are printed clearly on each slot, so you can see before you commit.

Do you still need coins?

Increasingly, no — but bring some anyway.

A growing share of machines take Suica, Pasmo and other IC cards (tap the reader, done), and many newer ones accept QR payment. But plenty of older machines, especially the cheap ones tucked into residential streets, are still coin-only.

The move that never fails: carry a ¥100 coin or two in a pocket. It weighs nothing and it works everywhere. If you're already carrying your phone with Suica loaded, even better — but the coin is the backstop.

Why this matters more than it sounds

Here's the thing that changes how you run in Japan: you don't need to carry water.

In most cities, a long summer run means planning a route around water fountains or running with a bottle or hydration vest. Here, you can head out with a coin in your pocket and know that hydration is 200 meters away in any direction, at any hour, in any neighborhood. Machines are lit and stocked at 5am. They're on riverside paths, at the base of mountain trails, outside temples.

That freedom is a big part of why running here feels so easy — and it's the same infrastructure logic that makes the konbini such a good recovery room.

So: Pocari for hot days, mugicha for taste, OS-1 only if you're in trouble, and a ¥100 coin in the pocket. That's the entire system.
