2. Prepare the manuscript in Microsoft Word, using A4 portrait orientation, 12-point character size, horizontal writing, and, in principle, double spacing between lines. Use a standard font (such as MS Mincho for Japanese or Times New Roman for English).
3. Enter special characters and symbols properly.
4. On the title page, indicate the type of paper/article, Japanese title, affiliated institution, affiliated department, authors' names, and authors' contact information (affiliation, postal/zip code, address, phone number, fax number, and email address).
5. Display the line numbers in the left column of the manuscript's main text.
6. At the bottom center of the manuscript, indicate the page number, with the title page being page 1.
7. For terminology, use modern kana orthography and, with the exception of medical terms, Joyo Kanji.
8. For weights and measures, use CGS units only.
9. For foreigners' names, drug names, and other scientific terms and chemical terms, use the original language.
10. Capitalize the first letter of proper nouns and German nouns.
11. When a foreign word can be expressed in Japanese, use Japanese notation in principle. Also, when a foreign word is written in katakana in a dictionary of medical terms or Japanese dictionary, it is preferable to write the word in the katakana used in the dictionary rather than in the original language.
12. Terms that are often repeated in a paper can be abbreviated. In such cases, write the full term the first time it appears and then use the abbreviated form thereafter.
Examples: distal gastrectomy (DG) peripheral parenteral nutrition (PPN)

14. In principle, use no more than three (3) Japanese keywords. Use appropriate terms that will enable searches to find the intended paper.
For original papers only, ensure that the purpose, target and method, results, and conclusions are in order and do not exceed 400 characters. For commissioned papers, review articles, clinical experience papers, case reports, institution updates, and research reports, regardless of type, limit the abstract to a maximum of 400 characters.
For original papers, write an English abstract. The English abstract should contain the same content as the Japanese abstract (A4, double spacing, 250 words maximum). The title, affiliated institution, and authors' names are not included in the 250 words.

Ethics Review of Research Paper
In accordance with the provisions of the "Ethical Guidelines for Life Science and Medical Research Involving Human Subjects", an appropriate review by the Ethics Review Committee registered in the "MHLW Research Ethics Review Committee Reporting System" must be received at the start of research.

For case reports, comply with the "Guidelines for Protecting Patient Privacy in the Society Meeting Presentations and Medical Papers, including Case Reports". Whenever possible, obtain consent to publish the paper from the patient or patient's family, and preferably state that fact in the main text.
