There's no mistaking summer in Japan. Any summertime anime scene will have their distinct chorus in the background. I say background, but sometimes it can feel as if you're wearing these things as headphones. They certainly have an awesome song.

The thing is, I miss them when they're gone. I look forward to their calls all year, as they signify that summer is really here. It's also a noise not familiar to the UK, so I only associate it with Japan. Cicadas in different countries seem to have a different pitch. Apparently it's only the males which call, but I've not looked close enough to check.
We go on our summer holiday today, so I'm not sure when I'll next make a new post.
