A traditional Japanese calendar contains seventy-two micro seasons (known as Kō), each marking a moment in Nature’s annual journey. Ice thickens on streams. The first peach blossoms appear. Wild geese fly north. The unfolding year is full of small acts of change, of renewal – observable to those ready to look. Plums turn yellow. Wagtails sing. Rice ripens. Silkworms feast on mulberry leaves. Effervescent, Ko, with its delicate striations, shifting and shining before the eye, evokes this custom of truly seeing, of watching the ephemeral and finding wonder.
