The Tohoku Journal of Experimental Medicine

Cover of the first issue

The Tohoku Journal of Experimental Medicine (TJEM) is a multidisciplinary English-language journal of medicine founded by the Tohoku Imperial University College of Medicine in 1920. TJEM is open to original articles in all branches of medical sciences and relevant areas, including clinical medicine, basic/translational medicine and social medicine. TJEM has contributed to the development of the world medical research. In April 2011, just after the Great East Japan Earthquake, TJEM added the field of disaster prevention sciences, including earthquake archeology. TJEM will continue to transmit the latest scientific information widely.

TJEM is one of the oldest periodicals in Japan. Since the first issue, TJEM has opened the door to the contributors all over the world, and introduced the results of medical research to the world widely (Top 30 Articles Most Frequently Cited). TJEM has been published continuously even at the height of the Second World War, except for the postwar 1946. Since 1981, the Tohoku University Medical Press, organized mainly by the professors of the Tohoku University School of Medicine, is responsible for monthly publication of TJEM. In addition, thanks to the support from the Japan Science and Technology Agency, all articles are available to the public at no cost, under Open Access by “Japan Science and Technology Information Aggregator, Electronic (J-STAGE).” The period between acceptance and publication averages about 16 days. This rapid process is one of the reasons why TJEM is supported from worldwide researchers.

For further improving the convenience of the readers, TJEM has adopted XML style with the support by the Grant-in-Aid for Scientific Research from the Japan Society for the Promotion of Science (JSPS) (abbreviated "Kakenhi" in Japanese) for "Strengthening International Dissemination of Information (No. 252007)." Accordingly, all articles are also available as HTML since April 2013.

Significance of publishing TJEM

The presence of high-level academic journals is one of a measure that indicates the cultural standard of a country. It is extremely important for Japan to publish English-language comprehensive medical journals such as TJEM and distribute it on an international scale. In fact, TJEM is found in the collections of the libraries of major universities and research institutions all over the world. Moreover, all articles published since 1920 are available to the public at no cost on website ( Over 25,000 articles are indeed downloaded every month. Tohoku University School of Medicine contributes to the development of the world medical research not only by promoting own research, but also publishing TJEM as a part of the international culture activity.

International peer review system

The editorial board consists of 12 members of the Tohoku University including the Editor-in-Chief and 28 members of outside university (17 of whom are non-Japanese, 13 countries). Its rapid and strict review process is carried out internationally. The review process (Review process averages: 15 days) for submissions are maintained with volunteer work based on collaboration between qualified referees around the world (in 2014, the total of 832 referees from 34 countries), the members of the editorial board and the Editor-in-Chief. Importantly, a large number of manuscripts are submitted from overseas, rather than universities and research institutions of Japan. Among 646 manuscripts in 2014, 79% were submitted from authors outside Japan. TJEM is the only journal in Japan that gets that degree support from overseas researchers. In 2014, the article acceptance rate was 18%.
