Japan's adult guardianship system has three types: guardianship (full incapacity, representative authority), curatorship (significantly insufficient capacity, consent authority for listed acts per Civil Code Art. 13), and assistance (insufficient capacity, specific authority granted by court). Guardians are appointed by family court, with fees typically ¥20K-60K/month based on estate size. Voluntary guardianship contracts can be made in advance via notarized deed.
