Aims and Scope

The Circulation Journal is the official publication of the Japanese Circulation Society. Contributions from non-members are also accepted. Articles deal with either clinical or experimental investigation of the cardiovascular and related systems.

The Journal will also consider the publication of review articles summarizing the present state of knowledge in a particular field. Manuscripts must conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals as presented in N Engl J Med 1997; 336: 309-315 (

Please also note the following information.

Transfer of Copyright on Theses Published in Circulation Journal and its Predecessor to the Society

The Japanese Circulation Society provides services related to the secondary use for academic purposes of theses published in Circulation Journal and its predecessor, and these services include giving consent to requests for reprinting and publishing electronic journals. Providing these services, however, requires the transfer by the authors of the copyright on these works, including rights of reproduction and public transmission, to the Society.

Since May 1990, it has been clearly stated in the contribution rules that the copyright on theses published in Japanese Circulation Journal belongs to the Japanese Circulation Society. There is, however, no copyright agreement on works published prior to May 1990 between their authors and the Society.

Properly speaking, it should be confirmed whether the copyright on all works, excluding those whose copyright has lapsed, has been individually transferred to the Society, but for the reason cited above, it is realistically difficult to contact a large number of authors for approval.

Therefore, the Society would like to seek approval for the items listed below from the authors of these works.

On theses published in Japanese Circulation Journal prior to May 1990,

  • For academic purposes, the Japanese Circulation Society possesses the rights of reproduction, screening and public transmission (including the right of making transmittable) to all or part of the works published in Japanese Circulation Journal, including its supplements, and its predecessor.
  • The Japanese Circulation Society holds the right to allow third parties to exercise the same rights as described above for academic purposes.
  • If the Japanese Circulation Society earns income from the acts described in the preceding two items, it will use such income for its operation.

If you do not agree to the items specified above, please notify the office of the Society to that effect by March 30, 2007. If you fail to notify us by the deadline, we will understand that you agree to the items.

If authors contact the Society after the deadline because they did not know about this notice for some reason or other, however, the Society will explain to and consult with them. Your kind understanding and cooperation would be highly appreciated.

Sincerely yours,

Hiroaki Shimokawa, MD

New full-color style of the Journal

Circulation Journal will be a full-color journal from the issue of Vol.74 No.1. Therefore, the cost for colored figures will not be charged.

Submission of manuscripts with color figures is encouraged.

Supplementary files

We, Circulation Journal, started to receive supplementary files in addition to main document, table(s) and figure(s), with the aim to enhance the scientific level of the Journal. Up to 3 supplementary files will be received per manuscript, including video files.

Please try to keep the total file size to 5 MB at the most. Please also note that all supplementary files undergo peer review, and they will be published only in the online journal after acceptance. Please see the Instructions to the authors for further information.

New Section of the Journal (Images in Cardiovascular Medicine)

We have launched a new section called “Images in Cardiovascular Medicine”, in which manuscripts reporting image(s) with high scientific importance and impact will be published (usually 2 papers per issue).

Please see the Instructions to Authors for the further information.

Case Reports in Circulation Journal are no longer considered

From October 31 2008, Circulation Journal will no longer consider Case Reports. The journal aims to speed up editorial procedures between acceptance and publication and improve the Impact Factor.

While we cannot consider Case Reports, we are pleased to consider contributions of potentially important clinical papers of several cases as Clinical Investigations or Rapid Communications.

We would very much appreciate your understanding and continued support for Circulation Journal.
