Some seasonal calligraphy specially for summertime!
The kanji are:
夏 = summer

It references the white fluffy clouds of summer which take many different shapes, including strange mountains!
This phrase is a special kind of Japaneses idiom known as a 四字熟語 (よじじゅくご、yo-ji-juku-go), or 4-character idiom. As the name suggests, these are idiomatic phrases made of 4 kanji characters.
