Japanese Kanji for Health: 健康 — What the Word Is Made Of

The Japanese kanji for health consists of two characters: 健 (strong, 11 strokes) and 康 (well-being, 11 strokes). Together, 健康 (kenkō) means 'health'. The first character contains the radical 'person' 亻, the second goes back to the idea of peace and prosperity. The word is not written with a single kanji.

Japanese health is assembled from 'strength' and 'peace': not the absence of illness, but a state in which the body is strong and life is well-ordered. Hence the greeting お元気ですか — a question not about symptoms, but about whether a person has vitality.
