After returning to the United States in 1935, Naka settled in California, where he would become a revolutionary force in the world of bonsai. He co-founded the California Bonsai Society in 1950 and served as its president for an incredible 32 years. He was instrumental in launching the National Bonsai Foundation, which led to the creation of the National Bonsai & Penjing Museum in Washington, D.C.. While he traveled the globe teaching, he famously declined offers to lecture in Japan, humbly stating that it would be "like trying to preach to Buddha".
