This is the official journal of The Japanese Circulation Society.

―編集長ご挨拶

It is a great honor for me to be appointed as the 18th Editor-in-Chief of the Circulation Journal. It is a tremendous responsibility to take on this new position, and I will do my utmost to fulfill it with sincerity.
   Circulation Journal is the English-language official journal of the Japanese Circulation Society, with a long tradition since 1935 and an Impact Factor of 3.1 as of 2024. The Journal currently receives more than 900 submissions per year from all over the world, resulting in the lower acceptance rate less than 21%.
   I would like to look back at the history of the Circulation Journal. The first Editor-in-Chief was Professor Toshikazu Mashimo, and the English name of the journal was “The Nippon Journal of Clinical Angio-Cardiology” when it was first published in 1935. After several years of suspension of publication after the war, the journal was reissued as “The Nippon Journal of Angio-Cardiology” in 1947. In 1953, the name was changed to the “Japanese Circulation Journal” as a response to internationalization. In 1980, it became an English-language journal publishing only English-language articles, and in 1994 received its first Impact Factor score. In 2002, the Journal began publishing abstracts of all published articles in PubMed and changed its name to the current “Circulation Journal”. In 2019, we launched a sister journal, Circulation Reports, and began transferring relevant papers from among the submissions to the Circulation Journal.
   During this period, successive generations of professional editors have guided the journal: Toshikazu Mashimo (1935–), Takeshi Kure (1941–), Renjiro Kaneko (1943–), Kanshi Sasa (1947–), Kenta Omori (1949–), Magojiro Maekawa (1950–), Masao Takayasu (1975–), Shoji Hayase (1979–), Satoru Murao (1985–), Kazuo Yamada (1988–), Chuichi Kawai (1992–), Tsuneaki Sugimoto (1995–), Yasuro Sugishita (1996–), Masunori Matsuzaki (2000–), Hiroaki Shimokawa (2008–), Toyoaki Murohara (2016–), and Toshihisa Anzai (2020–). The journal has ceaselessly published high-quality original papers by leading researchers from around the world, as well as interesting and up-to-date review articles. Again, thanks to the tireless efforts of the immediate-past editorial team lead by Professor Toshihisa Anzai, the Circulation Journal has enhanced its scientific contribution.
   From August 2024, a new editorial team (https://www.j-circ.or.jp/english/cj/editorial-board/) will take responsibility for handling the papers submitted to Circulation Journal. We are humbled by this heavy responsibility and simultaneously excited by the pleasure of contributing to the development of cardiovascular research. Once again, I would like to express my sincere appreciation for the dedicated contributions of the Editors, who represent cardiovascular disease researchers in Japan and abroad.
   As the leading journal in the Asia-Pacific region, we welcome submissions of advanced research in all areas of cardiovascular medicine. While we welcome high-profile randomized controlled trials and expert reviews of the latest developments in the field, we will also carefully review and help young, ambitious, future-oriented researchers brush up on their work. The Circulation Journal introduces the latest journal papers with the hashtag #circ_j on the X (formerly Twitter) site (https://x.com/JCIRC_IPR). Please visit the site and enjoy the data with illustrations of the latest papers.
   We hope to enhance the scientific value of the Circulation Journal together with researchers in Japan, Asia, and around the world. We can build on the excellent achievement of my predecessors to further expand the academic and scientific significance of the journal.
