"Yomenanohana," or kalimeris "yomena," is a weed that flowers unnoticed in the fields, and for Kyoko Mita, it is the perfect name for a museum for unknown artists.

Having taught a watercolors course titled "A Hundred Flowers of the Four Seasons" at the Asahi Culture Center in Tachikawa, western Tokyo, for 14 years, Mita, 60, has met many extremely talented students.

Her pupils are generally women. They range in age from 20 to 85, but many only started the course after turning 60.
