A sister university of Harvard was named Yenching University in Peking, China, and was an American missionary school. The Japanese Army could not come into this University until the Pearl Harbor attack. Torii was sent to this American area in China by the Institute, where his China anthropology studies reside, during the Second Sino-Japanese War. On 6 December 1951, Torii and his family returned to Tokyo, Japan. They arrived at Yokohama on a ship from Tientsin, China. In 1920 Torii was honored for an Ordre des Palmes Academiquesiques of France. The award disappeared within the university. In 1964 the "Torii' Memorial Museum" was established by Tokushima prefecture, at Naruto area. It is in a Japanese traditional castle on the top of Myoken Mountain. Funds came from local people, showing their memory and love for Ryuzo Torii. In 2010 the Museum moved to Tokushima city in the "Forest of Culture" area. In 1901 he married Kimiko, daughter of a famous samurai in Tokushima. She was talented in music, language and education. In the wake of Yoshino Sakuzō's criticism of Japan's Imperial ambitions in Korea, Torii aligned himself with those who justified Japanese annexation on the grounds that the contemporary consensus worldwide in linguistics, anthropology and archaeology was that the Korean and Japanese people were one and the same 'race/people' ("dōminzoku").
