All manuscripts must be written in English only. Authors who are not fluent in English must seek the assistance of a colleague who is a native English speaker and is familiar with the field of the work.

Length of articles: Articles may be revised by the manuscript which was submitted in 6ISTD. The maximum length of the text and references for each type of article should not be exceed about 25 pages. The manuscript are reports of original studies with new and valuable results. For the international readers, the manuscripts translated from Japanese to English may be submitted.

Manuscript form: A pdf file or the manuscript, including tables and figures, must be supplied. The abstract, text, references, tables, and figure legends must be typed double-space with wide margins more than 2.5 cm on one side of good-quality A4 paper. Incomplete or improperly prepared manuscripts will be returned to the authors without review.
A separate title page should be provided. The abstract, text, acknowledgments, references, tables, legends, and figures should begin on separate sheets and follow in that order. Standard abbreviations and units should be used: SI units are recommended. Abbreviations should be defined at first appearance, and their use in the title and abstract should be avoided. Generic names of chemicals should be used. Genus and species names should be typed in italic.

Title page: Titles should be brief, specific, and informative. Include the type of article; the full name(s) and affiliation(s) of authors; a short running headline; the full postal address to which proofs are to be sent, including a fax number, telephone number, and e-mail address; and 3-5 key words or phrases for indexing.

Abstract: A concise description (not more than 200 words) of the purpose, methods, results, and conclusions is required. Give only the most essential data. New and important aspects of the research should be emphasized.

Text: The text of experimental articles should be, if possible, divided into the following sections: Introduction, Theory, Materials, and methods (or Experimental), Results, and Discussion.

Symbols and equations: All symbols representing quantities will be set in italic unless otherwise indicated in the manuscript. Any special requirements for the appearance of symbols representing quantities and equations must be stated clearly in a note to the publisher. Any letters to be printed bold or in special fonts should be identified. Equation numbers flush right in parentheses.

References: Number references consecutively in the order cited in the text, not alphabetically. The accuracy of reference data is the authors' responsibility. Personal communications and unpublished data should not be included in the reference list but may be cited in parentheses in the text. If such a citation is from someone other than the authors, a letter should be submitted in which the direct quotation is given with the signature of its author. Unpublished papers accepted for publication may be included in the list by designating the journal followed by "in press" in parentheses. In the reference list, provide inclusive page numbers for all references and give the names of all authors (the use of "et al." in the reference list is unacceptable). Journal titles should be abbreviated according to The List of Serial Title Word Abbreviations published by the ISSN International Center. Citations of literature should be done in the text by numbers in brackets, e.g., [1]. For papers written in Japanese, follow the style of example 2.

Tables: Should be numbered consecutively with Arabic numerical in the order cited in the text. Each table should be given a brief informative title and should appear on a separate sheet. Explain in footnotes all abbreviations used.

Figures: In order to assure a readable appearance, the figures must be carefully designed. Especially the thickness of lines and the height of letters must be chosen such that no drop-outs occur after reduction of the figures to column size.
It is recommended to produce originals at a width of about 150 mm each. The thickness of lines should then be about 0.5 mm, the letter height should be 4.2 to 4.5 mm (12 to 14 pt). (In rare cases double-column figures are allowed. In this case the line-thickness should be about 0.3 mm, letter height 2 mm (7 pt).) Please do not use larger lettering than necessary and keep it at a constant size either in all parts of each figure or throughout the entire set of figures.
All figures, whether photographs, graphs, or diagrams, should be cited in the text and numbered sequentially with Arabic numerals. Each figure should be submitted on a separate sheet and should be of publication quality without any retouches in the printing office. A brief descriptive legend should be provided for each figure; legends should be typed on a separate sheet. The figures are labeled with their number and the name(s) of the author(s) on the front of the figure well outside the image region.
Related figures should be grouped into a plate on the one page. If plates are submitted, the figure parts, e.g., a, b, c, , should appear on the artwork.
