Given the dearth of ninja, out there, it is a good thing that there are still places you can visit which will give you tips on the kinds of skills true ninja need to survive.

It is important, for example, to know how to push on a wall so it will suddenly flip open and turn into a door. This is harder than it looks. You must know which side to push and how hard. Otherwise, you just look like you are throwing a temper tantrum.

It is also useful to know which floor boards conceal a deadly weapon in your home.

A true ninja adds to the myth that he and his kind can walk on water by wearing these “shoes.” They will enable you to cross a marsh (and thereby enter into castle property where, if you are skilled enough, you can assasinate someone), but not an actual ocean.

It is also good to know how to pull down the hidden English instruction signs. Admittedly, this would be a useful skill for many people, but so far it seems that only the ninja know where these signs are hidden.
