Tsuguko is a term used in Japanese culture to refer to a designated successor or apprentice, particularly in traditional arts and crafts. This role is often filled by someone who has shown exceptional skill and dedication, and they are expected to carry on the teachings and legacy of their mentor or master. In many cases, a Tsuguko is chosen based on their talent and commitment, ensuring that the knowledge and techniques of a particular art form are preserved for future generations. This practice is common in various disciplines, including Ikebana (flower arranging), calligraphy, and tea ceremony.
