A transitional month with only two genuinely date-bound moments — autumnal equinox week and the mid-autumn moon — both quiet, both observed in private. The rest is weather (lingering heat, the first typhoons) and atmospherics, not events. Sparse on purpose.

Around Sep 23 · Tradition
Autumn equivalent of the spring Higan. Same seven-day window centered on the autumnal equinox (national holiday), same family-grave visits, same ohagi — although in autumn the same sweet is technically called botamochi. The semantic split between ohagi and botamochi is one of those Japanese distinctions even native speakers will debate.

Mid-Sep (varies by lunar) · Tradition
Mid-autumn moon viewing — the night the moon is at its visually best on the old lunar calendar (usually mid-September, sometimes early October). Households set out small white tsukimi-dango (15 of them, stacked in a pyramid), susuki (silver grass), and seasonal fruit. The TV evening news will sometimes show the moon live for a beat. People actually step outside to look.
