"Sagi-so" in Japanese means Crane-weed. The flowers are said to look like flying Japanese Cranes (Grus japonensis). These birds are considered auspicious (long-life, fertility, etc.) and so the orchid has acquired the same baggage. A reputation for being hard to grow has only enhanced the mystique, and unfortunately, because of this, thousands are poached from the few remaining natural sites lefted in this over-developed country. Soon to be extinct, like every other plant of any distinction here in Japan.
