One of Japan's more popular authors of the last few months is an Osaka man who argues that the country's recent economic problems are a result of a conspiracy by ''international Jewish capital.''
Hundreds of thousands of Japanese readers have made best sellers of two books in which the writer, Masami Uno, asserts that Jews form a ''behind-the-scenes nation'' controlling major American corporations. He says the corporations include I.B.M., General Motors, Ford, Chrysler, Standard Oil, Exxon and A.T.&T.
''America is a Jewish nation,'' Mr. Uno writes.
