Micro-season 51 of 72 · Sep 18 – Sep 22
Swallows depart.
Tsubame saru
The swallows that arrived in spring now gather on telephone wires at dusk, preparing their long journey south as the air carries the first true coolness of autumn.
In the slanting light of mid-September evenings, swallows congregate in restless flocks, their calls sharp against the deepening blue. The air has shifted — no longer the heavy humidity of summer, but something thinner, cleaner, carrying the faint sweetness of ripening persimmons from nearby orchards. One feels the year beginning its slow turn inward.
Nature notes
Swallows perch in long rows along power lines, their numbers swelling each evening before they disappear southward by month's end. Silver grass (susuki) catches the low sun along riverbanks and hillsides, its plumes just beginning to unfurl. The cicada chorus has fallen silent, replaced by the evening songs of bell crickets and pine crickets, their delicate trilling carrying through open windows.

At the table
Pacific saury marinated in soy and mirin before grilling, the sweet glaze caramelizing against the fish's natural oils as autumn appetites deepen.
Freshly harvested chestnuts steamed with rice and a touch of salt, their subtle sweetness embodying the quiet abundance of early autumn.
Mixed rice cooked with an assortment of autumn mushrooms including shimeji and maitake, fragrant with the forest floor after rain.
Lotus root slices sandwiching seasoned meat, battered and fried — the satisfying crunch echoing the crispness arriving in the autumn air.
Cultural note
This micro-season marks the departure of swallows, birds long considered auspicious in Japan. Farmhouses traditionally welcomed their nesting under eaves, believing they brought good fortune and protected against fire. Their leaving signals autumn's true arrival, and in old farming villages, people would note the day of their departure as carefully as their spring return — a living calendar written in wing and sky.
燕去る空に残りし風の道

Swallows depart — / left behind in the sky / a road of wind
Where the swallows gathered yesterday, only the wire sways gently, holding the memory of wings.
