OSAKA — American author and scholar Chalmers Johnson, whose views on postwar Japan angered American academics and Japan experts in the late 1980s but influenced a generation of students studying the country, died Saturday in California at age 79.

The cause of death was not immediately known.

Born in Arizona in 1931, Johnson served in Japan with the navy during the Korean War. He received his Ph.D. from the University of California at Berkeley and taught there and at other UC institutions between 1962 and 1992.
