A Japanese year is more than four seasons. It turns through 24 solar terms — and within the "72 micro-seasons" (shichijuni-ko), the season shifts every five days. "Self-heal withers," "Cherry blossoms begin to open" — the delicate faces of the seasons that people of old once watched. Koyomi no Wa quietly tells you which one is unfolding today.
What season is today?
Today's micro-season, with clear, gentle notes anyone can read
A related ukiyo-e (public-domain masterpiece) and a classic haiku
Rokuyo, the lunar date, the sexagenary day, holidays, seasonal markers (Setsubun, Day of the Ox), and lucky days
The moon's phase, and the foods and flowers in season now
Beautiful, and quiet.
"The Wheel" — see the whole year as a circle of 24 terms
A washi-paper background that shifts with the seasons, and a tear-off-calendar opening
The dignified type of Shippori Mincho

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Updated daily columns so they no longer duplicate the 72 micro-season explanations.
The micro-season cards now focus on seasonal explanations, while the daily columns offer more companion reading on events, food culture, and everyday seasonal wisdom.
