The Japanese seem to have a gift of finding weird and wonderful new ways to surprise people... Here are 7 of the craziest!

1 Jurassic Prank
You're happily walking down a corridor with your early morning coffee when you see this. Is it an emergency? Is there a fire?

2. Water Fountain
This is a suped-up water fountain. Let's see how the every-day citizens react.

3. Elevator
This next one is a classic. Who isn't afraid of elevators?

4. Wet Surprise
You're happily walking down a corridor one morning, when suddenly... You're completely soaked from head to toe. The amount of effort they've put in to hiding these water pits is outstanding. This guy sees a suspicious man-hole cover and cleverly avoids it. Danger averted.

5. Random Guy
Sometimes it's enough just to be a random guy.

6. Mob Pranks
Just a couple of typical Japanese guys... With handbags... Walking down a typical Japanese street. Kentaro has just withdrawn his life savings and is on his way to finally buy a motorbike. No more walking down dodgy alleys for him...

7. The Apocalypse
Just a normal woman having her hair done. When the hairdresser leaves her alone for 10 minutes...

Which of these pranks did you think was the funniest?
