30 Lessons in about 10 months. After completing all the studies of the four curricula, lessons continue for acquisition of a Teacher’s Diploma (to be officially certified as Sogetsu teacher). At this stage, the curriculum composed of the four key words “Technique,” “Materials,” “Placement,” and “Creation” learned to get a more confident foundation of skills, knowledge, and greater creativity. At the same time, training is required to gain mental preparedness as a teacher. Upon completion of Curriculum 5, application can be made for Teacher’s Diploma Fourth Grade (the first stage of teacher’s diploma), a Hand-carved Kanban/Name board, and Hand-carved Sekisatsu/Nameplate.
