  • 精細せいさいCommon
    na-adjective, nounLeans toward 'fine; minute; detailed': it describes finely detailed work, descriptions, or data rather than a person's careful character, so it is seldom the word for a meticulous personality.

Choose 几帳面 for a meticulous personality, 細心 for careful caution, 周到 for thorough planning and preparation, 丹念 for painstaking care in handwork, and 精細 for finely detailed work or descriptions.
