There are rules in using the public toilets in Japan of course, just like how the sign shows it:

Let’s see now, sit properly, don’t squat on the toilet seat, don’t stick your head into the toilet bowl, don’t pee standing up (for the men), no fishing (what in the world are we to fish in there anyway?) and no dog style peeing at the urinals (very creative).

Then there is the more serious part of using signs about Japan’s public toilet:

I didn’t know using the toilet can be a threat to the strengthening of protection – unless, getting stuck in the toilet bowls requires attention from the national security.

OK, this is really funny. Before I looked closely at the photo, I thought the green guy is kids, you know, toilet size for kids:

Just in case the alien pays a visit, I suppose.

I bet the inventor of this got his/her idea while peeing:

How about that, battery than works by using pee. Not bad for an invention. Just make sure you dun get too overexcited and spill the “juice” in the battery or you’ll have a “scented” battery as well.

This drink is not as refreshing as it sound. Might be appetizing for a meat-eating zombie though.

To imagine the “frightfulness” of buying the ticket.

“Alice in the Wonderland” can tell you about a rocking door and other weird happenings.
