Meaning

Coexistence; symbiosis; the state of different individuals, communities, or species living together in mutual harmony or interdependence.

A noun used both in biology (symbiosis between species) and social/political discourse (intercultural coexistence, 多文化共生). In modern Japan, 共生社会 (inclusive society) is a key policy goal in discussions of disability, multiculturalism, and urban planning. Carries positive connotations of harmony and mutual benefit, going beyond mere tolerance to imply active, enriching interdependence.

2. 都市と自然の共生を目指した環境配慮型の開発が各地で進んでいる。 Environmentally sensitive development aimed at the coexistence of cities and nature is progressing in various areas.
