Nirinsou is a representative wildflower of Japan that heralds the arrival of spring in the mountains. It grows wild all over Japan, forms colonies on forest floors and along rivers in mountainous areas, and often blooms abundantly. Blooms in April in the lowlands and May in the highlands, The young leaves are a familiar wild flower for Japanese people who are also used for wild plants. In a certain grassy area, Nirinsou leaves spread like a carpet, Bathed in sunlight, the flowering Nirinsou sways comfortably in the gentle breeze. Many Nirinsou flowers seem to be singing in chorus celebrating the arrival of spring. I became obsessed with photographing them swaying in the wind. Nirinsou's English name is windflower, and the windflower name suits them very well.
