This article has been retracted from Japan Marketing Journal, Vol. 41, No. 4 (Mar. 31, 2022), pp. 18–28.
Reasons for retraction
The article mentioned above was placed under suspicion of self-plagiarism as well as duplicate submission from the author’s book, Profiting Strategy, Tokyo: Toyo Keizai, published on Nov. 26, 2021, by a reader. Accordingly, as publicly notified in the submission guidelines, an investigation of the facts was carried out by the Editor-in-Chief based on the procedure recommended by the Committee on Publication Ethics (COPE). The author admitted the charges, gave testimony that self-plagiarism and duplicate publication occurred because the above-mentioned book was published earlier than previously planned (in 2022 or later), and realized that the retraction should be instigated. Thus, the Editor-in-Chief, within his discretion, decided to retract the article.
