Abstract
Scholarly journals published by Japanese academic societies play important roles in dissemination and sharing of Japanese researchers' research results. To further promote their international distribution, internationalization of the Japanese academic journals in various aspects is required. In recent years, articles submitted from abroad to those journals seem to be increasing. In this study, we look the situation surrounding academic journals in Japan through detailed analysis on those journals with high percentages of foreign researchers' papers, based on the CJP database, produced by National Institute of Informatics.
