After returning to Japan, he quickly won clients for Wrightian residential designs, eventually totaling close to 400. He also continued to design buildings for the Jiyu Gakuen campus over the next 40 years, each suffused with the spirit that Wright and Arata instilled in the original school.

Raku's indefatigable energies were devoted to spreading the Gospel of Wright in a dozen other ways as well. He translated works on and by Wright, and wrote and lectured extensively himself. He was active on the committees to save the Imperial Hotel (which failed) and Jiyu Gakuen Myonichikan (which didn't), and led the very popular Wright Tours to the United States for over 10 years. Raku received the Wright Spirit Award in 2000 for his contributions to keeping the great architect's legacy alive in Japan.   (KS)
