So Much for Polite: What I Found at a Mountain Car Wash

I’d just spent the morning at a campsite tucked into the mountains — the kind of place where the loudest sound is a river and someone’s kid learning to skip stones. Tents scattered across a field, a few cars parked in the grass, everyone moving slower than usual. If you asked me to describe Japan in one image, I might have used that one.

Then I needed to rinse the mud off my car, and I found the local self-service car wash.

It’s called Car Pika Land Kujira — a small, unremarkable spot wedged against a quarried hillside, open from 6am to 9pm, the kind of place you’d drive past without a second look. But the signs posted around it told a completely different story than the campsite did.

The first one was a liability waiver, the kind you’d expect anywhere: if something happens while you’re using the equipment, the owner isn’t responsible. Fine. Standard.

The second was more specific than I expected: no washing muddy trucks or farm vehicles. Not “please be considerate” — an outright refusal. It took me a second to realize why. A place like this survives on a handful of drains built for regular cars, not a farmer hosing off half a rice paddy’s worth of mud from a truck bed. One customer with the wrong vehicle could clog the whole system for everyone else that day.

The third sign was the one that actually stopped me. In red and yellow, it warned against dumping outside trash — especially convenience store bento containers and empty cans — and said, in no uncertain terms, that anyone caught doing it would be reported to the police immediately. Cameras were watching. It wasn’t a suggestion. It read like a warning you’d post outside a building that had already had enough.

I think I’d absorbed, without really noticing, this idea that Japan runs on soft language — the kind of politeness that hedges everything, that would rather imply a rule than state it outright. And a lot of the time, that’s true. But somewhere between the campsite and the car wash, I remembered that softness is a choice Japan makes in certain contexts, not a personality trait. When something is actually at stake — shared equipment, a drain that only works if everyone follows one rule, a small business that’s clearly dealt with a specific problem more than once — the language stops hedging completely.

It reminded me of the “no trespassing” signs you’d see nailed to a fence back home, except somehow more specific, like whoever wrote it had a very exact incident in mind. Which, if I had to guess, they did.

If you want to see the actual signs (and the very peaceful campsite that came right before them), I filmed the whole thing — it’s up on the Threads account now. Have you ever had a “wait, really?” moment somewhere that seemed totally harmless at first?
