Japanese Actors

What is the likely possibility of meeting an actor on the streets of Tokyo? Or is there another way that you are more likely to meet them? Also, I heard that you can't take pictures with them but is this true?

It's true.
A lot of famous actors live in Tokyo.But meeting them is difficult,And we mustn't take apicture.
So you sould go to actors concert or handshake meeting.

There are no such places you can see the actor.
If you get to know the studio or TV station he goes regularly you may be able to meet him accidentally if you wait in front of the building.
And yes most of them refuse to take pics with fans. Some may not. It depends on his or his agent company's policy.

Hold up, wait a minute.... You mean if your in a public place, you cannot take a picture of an Actor or Actress or ask to take a picture with them?? You have to wait to be at the studio to take pictures of them?

Yuuki is that a law or is that a culture thing that you "mustn't take a picture"?

@Kay
Most of actors refuse to be taken pics. If you try to take one after being refused it will be criminal.

Kay: You could ask, but they're under no obligation to agree. And if you take the picture without their permission, in Japan, that's considered illegal (particularly if you then publish that picture). Japan has laws about privacy; if you intentionally photograph someone in a recognisable way in public without their permission, it's an offence. If you just take a picture of a sightseeing location, not intentionally photographing people (although they may end up in the photo), that's fine.

dot, dot, dot... thank you for explaining, I don't know how it works in Japan. So you cannot what they do in America, acting like a paparazzi.
