意味

Cheating on a romantic partner or having an affair — being unfaithful in a relationship.

浮気 covers a range of infidelity from emotional cheating to physical affairs. The boundary of what counts as 浮気 is a frequent topic of debate — some consider flirty LINE messages or eating dinner alone with someone else as 浮気, while others only count physical intimacy. The phrase 浮気性 (uwaki-shō) describes someone with a tendency to cheat.
