This is a type of orchid we call "Kocho-ran (胡蝶蘭)" in Japanese.
They are really gorgeous and smell heavenly. In Japan, this Orchid plant is often given as gifts to celebrate new companies or a launching of something.
These Orchid plants have long branches that droop over where the big flowers are growing neatly in a row. And it's a known fact, although I'm not sure if it's still true, that each branch costs about 10,000 yen. (About $100...or a little less now with the high yen rate.) Isn't that ridiculously expensive?
Most of these Orchid plants in the photo bellow had 5 branches each!
