Tsubame (Swallow)

Swallows come to Japan at the end of spring, and they spend a summer and raise chicks.

They usually build a nest of mud and grasses around human habitation.
Many Japanese look forward to the chickes growing safely.

Swallows are one of the most familiar presence for Japanese for a long time. So the motif of swallow is often used in a design of kimono and obi for summer.
