Kigo Rikka (りっか 立夏), or Summer Stand, is one of the 24 solar terms (にじゅうよんせっき 二十四節気).
Kanji origin:
Kanji 立 means "stand," "rise," or "establish."
Kanji 夏 means "summer."
Therefore, kanji 立夏 literally means "standing summer."
Summer Stand:
At the Summer Stand, the temperature changes from warm to hot. Light changes from the mild light of spring to the dazzling light of summer. Our hearts get excited, and outfits become lighter in advance of the season.
In the Japanese archipelago, Summer Stand falls after the flower-viewing season (はなみ 花見).
Writing tips:
For a haiku starter, "preparation for summer" might be a good motif.
Typical symbols are "open windows," "shorts," or "sandals" for beginner writers because these items express the summer mood in a straightforward way.
Other symbols are "ice cream" or "refrigerators" for intermediate writers because these items express the summer mood in an indirect way.
