徳川家達
One of Grew's closest and most influential Japanese friends and allies was Prince Tokugawa Iesato (1863–1940), the president of Japan's upper house, the House of Peers. During most of the 1930s, both men worked together in various creative diplomatic ways to promote goodwill between their nations. The 1937 photo illustration to the right showd them having tea together after attending a goodwill event to commemorate the 25th anniversary Japanese gift of cherry blossom trees to the US in 1912. The Garden Club of America reciprocated by giving flowering trees to Japan.
