霞 ・ かすみ ・ kasumi
Mist. Haze. A stylized design of mist banks or clouds. Often depicted as interconnected horizontal shapes with rounded corners, creating the impression of floating clouds of mist. The motif can be used as-is, but is often part of an overall design.
Although as a pattern in kimono design the word kasumi mostly comes up, there are several words to indicate haze, mist, and fog in Japanese used depending on the type and/or season. Kasumi (霞・かすみ, -gasumi) and oboro (朧・おぼろ) refer to haze and mist of spring, whereas kiri (霧・きり, -giri) refers to the fog of autumn and winter. Kasumi mostly refers to mist or haze in daytime or evening. Oboro seems to refer more to nightly mist or haze. Summer being in between uses a mix of kasumi and kiri.
