Purpose: The objective of this study was to compare Scopus journals published in East Asian countries—China, Japan, South Korea, and Taiwan—in terms of their open access status and metrics and to explore the implications of those findings for South Korea.Methods: To conduct this study, we selected four East Asian countries: China, Japan, South Korea, and Taiwan. We used journal information provided by SCImago Journal Rank (SJR) and Scopus. The following parameters were analyzed for journals published in East Asian countries: open access status, subject categories, quartiles, number of published documents, h-index, publishers, and citation rate.Results: In all East Asian countries, numerous commercial publishers publish journals. One exception is Science Press, a Chinese government-sponsored publisher, which published the largest number of journals in the East Asian region. Japan had the highest median number of years covered by SJR. However, the proportion of Q1 journals in Japan was the lowest of the East Asian countries. South Korea had the highest proportion of Q1 journals in the country’s total journal production. Publishers in South Korea published more open access journals than any other East Asian country. Despite publishing a high proportion of prestigious journals, South Korea lagged behind China and Japan in the number of Scopus-indexed journals.Conclusion: The findings indicate that South Korea has made significant progress in locally producing influential journals over the years. However, more efforts to publish international journals are required for South Korea to increase the number of Scopus journals.
