Pecteilis radiata

Pecteilis radiata (syn. Habenaria radiata) is a species of orchid found in China, Japan, Korea and Russia. It is commonly known as the white egret flower, fringed orchid or sagisō (鷺草). Pecteilis radiata grows with small tubers, from which grasslike leaves emerge. Flower spikes, which can be up to 50 cm tall, produce 2-3 white flowers that bloom in late summer. It is not to be confused with the white fringed orchid Platanthera praeclara, which is a North American species. Pecteilis radiata is the official flower of Setagaya ward, Tokyo.
