What Is “Shimo yamite nae izuru” (霜止出苗)?

"Shimo yamite nae izuru" (霜止出苗) is one of Japan's Shichijūni Kō (72 microseasons), a traditional seasonal calendar that divides the year into finely observed changes in nature. This particular microseason falls around late April each year. It is the second phase of Kokuu (穀雨, "Grain Rain") in the Nijūshi Sekki (24 solar terms), and its name means "the frost ends and rice seedlings begin to grow." It marks the time when the chill of early spring softens and full-scale farming activities begin in the fields and rice paddies. During the season of "Shimo yamite nae izuru," preparations for rice planting are underway throughout Japan, and the fresh green of young rice seedlings becomes increasingly visible. The sharp cold of the mornings and evenings gradually fades, bringing a steadier warmth that helps crops grow more easily. It is also a time when the transition from spring to early summer can be strongly felt in nature, with vibrant fresh greenery covering the mountains and colorful flowers coming into full bloom. The Shichijūni Kō (72 microseasons) calendar reflects the wisdom of people in old Japan, who lived with deep awareness of even the smallest changes in the natural world. The phrase "Shimo yamite nae izuru" beautifully expresses Japan's seasonal culture and its close connection to agriculture. Even today, it remains a beloved seasonal expression, often appearing in haiku, traditional Japanese culture, and seasonal greetings.
