This book deals with the topic of English loanwords in theJapanese language. Due to strong American influence after WW II, Anglicisms have become a monopolizing force among Western loanwords in Japan and make up about 90% oftheir stock, and almost 10% of the entire Japanese vocabulary.This monograph explores, among other things, their history,creation, functions and exemplary integration into thelanguage, which assimilates loanwords completely into theJapanese phonological and morphological system. It analyzes reactions from politics and society and deals extensively withthe issue of comprehension, showing that Anglicisms can indeedbe an enrichment to a language, even in great numbers.
