In the old Japanese calendar, the year was not divided into four seasons. It was divided into seventy-two.

Each kō (候) lasted roughly five days and was named for a natural event: "East winds melt the ice." "Bush warblers sing in the mountains." "Peach blossoms begin to bloom." "Swallows return." "Chrysanthemums bloom yellow." "Bears retreat to their dens."

Seventy-two names. Seventy-two invitations to notice that the world has changed — again — since you last looked.

Why So Many Seasons?

Because change happens continuously, not quarterly. The Western four-season model is useful but coarse. Spring is not one thing. It is a procession of micro-events: the first thaw, the first bud, the first blossom, the first warmth, the first green. Each of these is distinct. Each deserves its own attention.

The seventy-two seasons are a training programme for awareness. They teach you to notice the world at a resolution that most modern people never achieve. When you know that this particular week is "Swallows return," you begin to look for swallows. You begin to notice the sky differently. You begin to pay attention to what is arriving and what is departing — not in the abstract, but in the specific, observable, daily reality of the natural world.

What This Teaches Us

We are not paying attention. Not to nature, not to the passage of time, not to the small changes that accumulate into large ones. We move through our days on autopilot, noticing only the dramatic — the storm, the heatwave, the first snow — and missing the thousands of subtle transitions in between.

The seventy-two seasons say: the transitions are the substance. The space between the dramatic events is where life is actually happening. Pay attention to it.

How to Start

You don't need to memorise seventy-two Japanese season names. You need to step outside each morning and notice one thing that is different from yesterday. The light. The temperature. The sound of the birds. The colour of the leaves. One observation, each day, for a month. By the end of the month, you will be living in more seasons than four.
