Soho Study Group, founded in 1997 by Soho Sakai, Riji, and her students, provides continuing study of Sogetsu School's curriculum and concepts. Soho Sakai, is a renowned master teacher and artist; her students number in the hundreds. Many of her students have graduated to become strong and devoted teachers of Sogetsu School


We host workshops for our members, and present flower shows, demonstrations and displays at various community locations. In October 2007, we presented a 2-day Sogetsu 80th Anniversary celebration at the Oakland Museum of California, Floral Sculptures in the Gardens of the Museum.


We are a dedicated group of individuals who continue our study of Japanese flower arranging with workshops and educational meetings. Geared to expanding the membership's knowledge and understanding of the principles of Sogetsu Ikebana, and encouraging their creativity and artistic abilities, the meetings offer an opportunity to exchange ideas and grow as Ikebana designers.


With over 170 current members, more than 80 of them teachers, Soho Study Group represents a significant force in the contemporary Bay Area Ikebana community.
