What Is “Niji kakurete miezu” (虹蔵不見)?

"Niji Kakurete Miezu" (虹蔵不見, "Rainbows Hide and Are No Longer Seen") is one of Japan's "Shichijūni Kō (72 microseasons)" and marks the first microseason of "Shōsetsu" (小雪) within the "Nijūshi Sekki (24 solar terms)". It typically falls between November 22 and November 26 each year and refers to the time when "rainbows disappear from the sky and can no longer be seen." While rainbows are common in spring and summer, they gradually become less visible as winter approaches, when the air grows drier and sunlight becomes weaker. The "Shichijūni Kō (72 microseasons)" is a traditional calendar that reflects the ancient Japanese appreciation for subtle changes in nature and the progression of the seasons. Among these seasonal markers, "Niji Kakurete Miezu" is especially known for capturing the quiet transition from autumn to winter. The character "蔵" ("to hide" or "to be concealed") evokes the image of rainbows retreating from the sky, as though preparing themselves for the coming winter. In recent years, interest in the "Shichijūni Kō (72 microseasons)", traditional Japanese month names, and seasonal expressions has grown significantly. As a result, "Niji Kakurete Miezu" has attracted attention in contexts such as haiku, traditional Japanese lifestyles, and seasonal greetings. For those interested in the beauty of Japanese culture and its rich seasonal vocabulary, "Niji Kakurete Miezu" offers a glimpse into the sensitivity and deep connection to nature that have long characterized the Japanese way of life.
