同居, pronounced dokyo in Japanese, refers to cohabitation or living together. This term describes the arrangement where two or more people share the same living space, typically a home or apartment. 同居 can occur among various groups, such as family members, romantic partners, friends, or roommates.

In the context of family, dokyo often refers to multiple generations living under one roof, such as grandparents, parents, and children. This arrangement can have cultural significance, offering benefits like shared responsibilities, financial savings, and strengthened family bonds. However, it can also present challenges related to privacy, space, and differing lifestyles.

In non-family contexts, dokyo is common among students, young professionals, or individuals seeking to reduce living costs by sharing rent and utilities.
