Since the end of World War II the Japanese have become an economic power in the world. As an economic power the Japanese have many dealings with the United States. After World War II there was a tremendous rise in Japanese immigration to the United States. While immigration was not new to the United States the Japanese immigrants were very different from former immigrant groups (Montero, 1981). One major difference is the Japanese were able to maintain a standard of living that was close to that of the majority group (Jiobu, 1981). Because Japanese immigrants have accomplished this, it is important to study what they do differently that allows them to adjust to life in the United States more readily. One area where Japanese society is very unique is in their worship of religions. They do not restrict themselves to one religion but in fact many individuals practice two or more (Ruiz, 1969). Whether Japanese immigrants after their practice of various religion upon immigration to American or maintain it has not been a topic of study that has been inquired into. This proposed study would investigate what changes occur in the Japanese spiritual practices upon immigration to America as well as hypothesize what the causes and benefits of the changes are.
