As tensions between the US and Japan increased during 1941, the US government compiled a list of suspected 'subversives' that included many Buddhists priests. Japanese American Christian ministers were not targeted in the same way. After the Japanese attack on Pearl Harbor, military authorities quickly arrested and detained many of the people on this list. While Japanese Americans living in Hawaii were not subject to removal and incarceration, the islands spent the war under martial law. The military authorities placed restrictions on the ability of Buddhists, in particular, to gather and worship as normal at places like the Hawaii Shingon Mission. Suspicious neighbors even vandalized many shrines and temples in Hawaii. Fortunately, the Mission survived and remains as a testament to the rich and resilient history of Buddhism in America.
