People in Japan usually have a tea ceremony on special events - Japanese festivals or holidays. Japanese Tea ceremonies are also held daily at Japanese tea gardens - there are a few of them in Tokyo (see http://www.tokyo-top-guide.com/Japanese_Gardens.html). Admission fee to these Japanese tea gardens is very reasonable, and the tea ceremony is a shorter version of the traditional Japanese tea ceremony ritual. If you are coming as a tourist to Tokyo - the Okura hotel also holds a tea ceremony in a private room, this naturally costs more than the Japanese tea gardens.
The Japanese tea ceremony can be held indoors or outdoors. If it is indoors, it is a a simple room with a scroll and a place to store the tea equipment.
It's not really a ceremony, but rather a ceremonious way of preparing and drinking tea. "Tea Ceremony" is just what we call it in English. In Japanese it's called "The Way of Tea."
Most surviving ceramics from this period appear to be tea sets for use in the traditional Japanese tea ceremony, or chanoyu.
In a Japanese tea ceremony you are either invited by the tea master or someone arranges a ceremony at a tea house and they invite you as a guest. However at events in temples you just need to pay for a ticket
