Samidare (五月雨 – Early Summer Rain)
The rainy season, known as tsuyu (梅雨) in Japan, has begun nationwide.
The light rain that lasts for a long term in this season is referred to as samidare (五月雨) in Japanese.
Sa (さ) means “god of fields” and midare (みだれ), which is also written as 水垂れ (literally meaning “water dropping”) and means “rain.”
In other words, this term implies that rain in the rainy season is a blessing for farmers who grow crops.
Incidentally, the Chinese characters for samidare is 五月雨, the literal meaning of which is “Fifth month rain.”
ちなみに、さみだれの漢字「五月雨」の文字どおりの意味は “May rain” です。
Since the month here is the lunar calendar, “5th month” corresponds to around the middle of June in the current calendar.
