【URL】

This is the URL assigned to the Detailed Information Window for each individual wooden tablet. The particular webpage can be accessed using this URL.

【ccession Number】

When a tablet has been assigned a number in a site report, that number is given here. Otherwise the value is given as zero.

【Text】

In principle, characters are displayed in their currently used forms, although exceptions are made for characters such as 龍, 廣, 寶, 嶋, 籠, etc.
Symbols used in transliterations of the text are given in the following table.

【Dimensions】

Dimensions are given in the three components of Length, Width, and Thickness (in milimeters).
Length is in principle the lineal measure in the direction in which the characters are written. It includes data reported through such terms as "length," "long side" and other variants of the term "long," plus "height," "item height" and other variants of the term "height."
Width includes data reported through terms including "width," "diameter," and also "external/internal dimensions."
Thickness also includes data reported as "depth" (front to back).
When a single wooden tablet is divided into multiple fragments, the dimensions of each fragment are given individually and separated as a set with a semicolon (in some cases the individual parts are labeled as "a," "b," etc.).
欠損や二次的整形によって原形を保っていない場合には、数字に（　）を付けました。但し、『木簡研究』では二次的整形の場合には（　）を付けないことになっています。 『木簡研究』掲載のデータをそのまま収録していますので、『木簡研究』から収録した木簡の寸法についてはご留意ください。なお、削屑については寸法を示していません。

【Form no】

This indicates the extant form of the tablet. The Nara National Research Institute for Cultural Properties currently uses the numbers in the table below to designate 18 types of form. The "end" of an item is considered to be a side oriented perpendicular to the grain of the wood. Also, as some investigating agencies have their own systems of form numbers, the particular site report may need to be consulted. Additionally, in some cases an extra digit precedes the form number, indicating the period
(5=Asuka, 6=Nara, 7=Heian).

【Bibliographic Information】

Bibliographic data for the report on the item. If a detailed report for the item appears after an initial general one, data given for the item's content are in principle those of the latter report with the earlier data deleted, and bibliographic data included for both reports.
There are cases however where the contents of the general and detailed reports are included in separate records in overlapping fashion.
For items reported in the Proceedings of the Japanese Society for the Study of Wooden Documents as well as in general or detailed reports, multiple bibliographic references are given.
Individual reports other than those mentioned above are not included until they are covered in the Proceeedings; hence the latter should be consulted for complete bibliographic data.
When multiple transliterations have been published, efforts are made to include only the latest versions, but as there are cases where this has yet to be done or multiple entries for the same tablet, the sources or the investigative agencies should be cross-checked carefully.
The sources currently covered in the database and their shortened references are given in the following table. (We regret that these data are available only in Japanese).

【Variant Character】

Explanation provided for characters in the text of a wooden tablet which cannot be reproduced as a printed character (or symbol).
In particular, characters not included in the UTF-8 character code are indicated as "〓," and explanations may be given in terms of the character's components (example: The character 〓 is 皿 written beneath 沈). Also, when notes are provided in a published report on a character's shape or written manner, that information is summarized.

【Wooden Tablet Shapes*】

Explanations of the shapes of tablets, noting missing portions, etc. Also, the uses for the tablets are sometimes given.

【ree Species*】

The type of tree used for the tablet. The following symbols are used: H = cypress; S = cedar; N = conifer; B = broadleaf; F = unclear, other.

【Grain Direction*】

The manner in which the wood of the tablet was cut. The following symbols are used: I = flat grain; M = straight grain; F = unclear, other.

【Site Name】

Name of the site where the item was recovered.

【Location】

The site or location where the tablet was recovered.

【Investigating party】

Name of the agency investigating the site where the item was recovered.

【Excavation No.】

Number of the excavation in which the item was recovered at the site. Please refer to the relevant bibliographic citation.

【Feature No.】

Number of the feature from which the item was recovered at the site. Please refer to the relevant bibliographic citation for details.

【Excavation precinct】

Designation of the excavation precinct from which the item was recovered at the site. Please refer to the relevant bibliographic citation.

【Tablet Type*】

The classification based on the tablet contents. A question mark at the end denotes an inference.

【Ancient Province】

Place names written on tablets are entered using orthographic forms found in Ikebe Wataru’s Wamyō ruijushō gungōriekimei kōshō (hereafter Wamyō ruijushō) as much as possible.
For indeterminate place names, or those for which multiple possibilities exist, these are listed successively with each candidate enclosed in parentheses; when one of the candidates is considered most probable it is listed first, without parentheses. When the name at the time the tablet was written differed from the form found in Wamyō ruijushō, the latter is written first, followed by the former enclosed in angle brackets: Wamyō ruijushō name 〈name in use at time of the tablet〉.

【Personal Name】

Personal names written on tablets. Because they are listed exactly as written, often only a portion of the entire name is given.
Indeterminate characters are enclosed in parentheses, and inferred names are enclosed with lenticular brackets (which look like this: 【】).

【Japanese Era Name】

Dates written on tablets are entered using Japanese era names for the years. Numbers have been transliterated into Arabic numerals.

【Western Calendar】

Western calendar years corresponding to years given in Japanese era names are entered, using Arabic numberals.

【Variant Character*】

Explanation of the form or contents of a tablet.

【Research Literature Data】

Research literature dealing with the wooden tablet that has been searched is listed. As bibliographic data, the title, author, journal, volume/issue, and year of publication are displayed.
For the journal, in principle only the initial report for the item is displayed. However, for monographs in which an item is secondarily reported with corrections or re-editing of the initial data, these are given precedence, and the relevant chapter title is displayed.
Accordingly, in some cases multiple links to literature exist, and in the Comments column notes such as "Previous two reports are corrected" or "Section X only is previously published, the remainder is new content," indicating the situation of revision of data as far as can be ascertained.
Also, links are displayed to other databases (Oguchi Masashi's "Ancient Japanese Historical Research Literature Inventory Database" of the Hosei University Research Center for International Japanese Studies, and the National Institute of Informatics CiNii [Scholarly and Academic Information Navigator]).
※For the time being, coverage is limited to articles appearing in the journal Proceedings of the Japanese Society for the Study of Wooden Documents, but augmenting the data for other research literature on a periodic basis is planned for the future.

【Annotations of words and phrases of the text】

This tree diagram shows the results of semantic classification of the terms in the text.Semantic classifications consist of three levels, and each term is marked with a tag (category or subcategory label). Tags often used in wooden tablets are linked with explanations in the glossary of the Mokkan Hiroba web site. These tags are the list of terms for a Category search.
