Every other hotel I've been to in Japan was excellent, but this one was.... not.

We walk in, the clerk didn't speak any English. That's fine, I don't expect any different, and my travelling companion grew up in Yokohama and is fluent. (But is relevant in a second.)

Got to the room, sat down on the futon (a mat on the floor, very common in Japanese hotels that don't cater to foreigners), and I look at the pretty spotted pattern on the wallpaper.

Then I realized that the spots were moving.

Then my companion noticed the same moving spots on the blankets we were sitting on, it was some type of small round beetle.

We immediately marched down to the front desk to demand a refund and leave. Except that my companion can't do that, Japanese is too polite to demand. So I had to start yelling in English (a great language for yelling, even (especially?) if the listener doesn't speak it). We finally got a refund and headed out to find a place that wasn't crawling with bugs.
