Kiyoshi Yasui   - Japanese Traditional Architect (December 6, 1925 - October 30, 2010)

The Japanese Gardening Organization honors the late Kiyoshi Yasui who’s knowledge, vision and sharing was the inspiration for this organization. Yasui-sensei recognized that the world was changing and thought the traditional Japanese way of ‘transfer of knowledge’ may not endure.  With this idea, he shared his knowledge of Japanese gardens and requested that it be provided to all those interested in learning about the traditions, methods and enjoyment of Japanese gardens.


Biography – Kiyoshi Yasui was born in Muko-cho, Kyoto in 1925 as the 14th-generation of a master builder family having a history of over 350 years.  After graduating from Ritsumeikan University, Kyoto in 1945, he joined his father’s company, Yasuimoku Koumuten Company, Ltd., and was involved in many projects in renovation, restoration and construction of authentic traditional Japanese structures such as temple, shrines, palaces and tea houses. He also worked actively to train successors in the field of traditional architecture and Japanese garden. For example, he founded the traditional architecture course in Kuma industrial high school, Kumamoto, and gave instruction to the students for 16 years. In 2001, he left the company and established his own workshop “Sei-Juku” to provide high level expertise to professionals from around the country through practical work, including preservation of cultural property and construction of sukiya-style house*. In later years, he took up many valuable timbers from traditional structures which were otherwise to be demolished and wasted, and has reserved them hoping to reuse. Before realizing his hope, Yasui died suddenly on 30 October 2010, aged 85. His will has been inherited by the members of Sei-Juku.

*Sukiya: One type of Japanese residential architectural style. The word originally denoted a building in which tea ceremony was held. It has come to indicate a style of designing public facilities and private homes based on tea house aesthetics, characterised by a use of natural materials. The beauty of sukiya-zukuri comes from the delicate sensibility of slender wood elements and other natural materials used, and the simplicity of ornamentation, if any. (source: Wikipedia).

安井清  (1925年12月6日 – 2010年10月30日) 日本の伝統建築家

安 井清は、1925年、350年以上の歴史を持つ棟梁家の14代目として生まれた。1945年立命館大学卒業後、父の会社である安井杢工務店に入社。社寺、 宮殿、茶室等の日本伝統建築の修理、建築プロジェクトに多数携わる。一方、伝統建築と日本庭園分野における後継者の育成にも積極的に取り組んだ。熊本県の 球磨工業高校に伝統建築科を創設し、16年間生徒の指導にあたった。また2001年に安井杢工務店を退社してからは自身のワークショップ「清塾」を設立。 文化財の保護や数寄屋建築等の実際の仕事を通じて、全国から集まった職人に高い専門技術を伝えた。後年は解体処分される伝統建築から貴重な建材を引き取っ て保管し、いつか再利用したいと考えていた。その実現をまたず、2010年10月30日、病気のため急逝した。享年85歳。彼の遺志は残された清塾生が引 き継いでいる。
