September 12th – September 17th, 2025 is Autumn – Middle of HAKURO (White dew)-44th KOU “Wagtails sing.”
Wagtails mainly live near water area. Both white wagtails and common wagtails can be seen around the SAI River.
Their chirping sounds match the autumn sky, especially in SHINSHU’s clear sky well. However, the autumn rain front has been stagnant for a while, so the clear autumn sky is hard to see. The wagtails also seem to be singing quieter than usual.
If you chase one, it will fly a little way ahead, stop, and walk around while swinging its long tail up and down. It doesn’t look like it’s trying to run away.
Japanese mythology says that the divine couple IZANGI and IZANAMI have learned how to have children by watching the movement of the wagtail’s tail.
