This article explores the legal age for living alone in Japan and how minors can manage to do so. The legal age of adulthood is 20 years old, meaning that anyone under this age is not legally allowed to live alone without an adult guarantor or guardian. There are visa options available to those over 18 years old, such as an educational visa or working visa that allows minors to stay in the country without having an adult guarantor or guardian. Living alone at an early age has both pros and cons depending on individual circumstances, and tips are provided on how to live independently in Japan. Resources such as websites, counseling services and job search assistance are also discussed.
