The United States is a dangerous place -- especially compared to Japan. The gun incident that killed a Japanese exchange student who was looking for a halloween party typifies the fear Japanese have about the United States. Producer Mary Beth Carlson examines the difference in safety between the countries, and interviews several Japanese women who teach courses in how to understand life in the United States -- including such American phrases as "duck" and "face down." She also talks with an American jazz musician who has found a safer way of life in Tokyo.
