Hansō Sōshitsu (Sen Sōshitsu XV) — 15th-generation Urasenke tea master

Lineage and name

The title Sen Sōshitsu denotes both lineage and office. The practice of inheriting a hereditary name is common among classical Japanese arts: the personal family name and the professional iemoto name are distinct. In this naming convention the ordinal (XV) marks his place in a continuous line of teachers responsible for preserving their school's forms and teachings.

Role and activities

As an iemoto of Urasenke, Hansō Sōshitsu has overseen instruction, codification of procedures, and outreach. His duties typically include maintaining traditional procedures of tea masters, authorizing instructors, and representing the school in cultural exchanges. He has been associated with efforts to teach chanoyu to a broad public and to adapt educational programs for both Japanese and international students.

Typical responsibilities of an iemoto include:

• Teaching core rituals and utensils, and preserving ceremonial etiquette.
• Issuing certificates and leading formal training programs.
• Promoting tea culture through public events, lectures, and publications.

Urasenke itself is one of the main streams of the Sen family tradition that trace back to Sen no Rikyū, the influential 16th-century tea master whose aesthetic and procedural innovations shaped chanoyu. Urasenke, alongside related lines, emphasizes both the spiritual and practical aspects of the tea gathering, balancing prescribed forms with adaptability for modern audiences.

Hansō Sōshitsu's tenure is part of a long institutional history in which successive iemoto have acted as cultural custodians: safeguarding tea-school archives, fostering teacher networks, and serving as visible representatives of Japanese intangible cultural heritage.
