１ 近代日本の政治経済社会における富裕層の階層的、階級的変化の解明という研究目的に基づき行ってきた『人事興信録』のデータベース化について、第6次科学技術基本計画における人文社会科学の「総合知」創出のための研究データとしてどのように位置づけることができるのかにつき検討を行い、日本学術会議のシンポジウム「総合知創出に向けた人文・社会科学のデジタル研究基盤の構築の現在」（2022年1月22日）において報告を行った。
２ 『人事興信録』の第七版から第十版までの四つの連続した版を使って採録者の変化を分析し次の知見を得、論文として発表した。
・1度の改訂により、採録者が3～4割程度入れ替わっていることが明らかになった。
・テキストマイニングを用いて、継続率と職業に用いられている用語の関係を調査した。これにより、時期ごとに継続率が低い傾向にある業種を発見できることがわかった。 -
Elucidating the legislative history of the Civil Code and Commercial Code by developing the platform

This research has constructed an information platform for a cross-sectional study of the Meiji Civil Code, Meiji Commercial Code, Old Civil Code (Boissonade Civil Code), and Old Commercial Code (Roesler Commercial Code). This system provides access to the previously little-known drafts of the Old Commercial Code at each drafting stage, the legislative reference of the Meiji Commercial Code, the legislative reasons for each code, and a large volume of proceedings in chronological order.
This study quantitatively evaluated the similarities in the content through an exhaustive comparison of the referenced legislative examples. However, it is difficult to grasp the overall picture by simply arranging numerical values of similarity. Therefore, this study examined ways to visualize and show relationships based on similarity. -
Creation of a research base through a comparison of the terminology of six basics laws in East Asian jurisdictions

Grant amount：\31330000 （ Direct Cost: \24100000 、 Indirect Cost：\7230000 ）
This project successfully created an international network of legal experts who wish to know foreign laws deeper through the comparison of laws of Japan, China, Korea, and Taiwan. Based on this network, the project taught jointly at some graduate programs and produced various illustrations to highlight functional differences of the same terms. The illustrations are particularly useful in comparison of legislative drafting, procedure laws, and the use of the law. A vocabulary analysis clarified that each basic law uses a fairly unique set of vocabulary without sharing common terms. The further analysis of what terms six basic laws of four jurisdictions share waits for the completion of a shared vocabulary database for comparative law.

Political and Economic analysis of oligarchy network in modern Japan

Grant amount：\43550000 （ Direct Cost: \33500000 、 Indirect Cost：\10050000 ）
Regarding "Jinji Koshinroku (Who's who)," which is a book material, we constructed a database that stores its structured full-text by utilizing experience in information processing in legal informatics. This database makes it possible to extract and analyze the data needed by researchers in Japanese political history, Japanese economic history, and comparative politics.
Concerning the unexplained modern Japanese rich and elites, by using visualization of relative networks, we examine the "modern feudal social class" and point out its characteristics through intergenerational income mobility and educational background. -
Analysis of the relationship between Japanese Civil Code and foreign law in drafting process

Grant amount：\3900000 （ Direct Cost: \3000000 、 Indirect Cost：\900000 ）
The purpose of this research is clarifying the legislative history by identifying the various information of the basis of the Civil Code compilation and analyzing the relationships between them.
This research compared with the Civil Code and the Commercial Code to clarify the features of legislative reference of the Civil Code. As a result, it became clear that in the Civil Code, the percentage of references in Germany is considerably lower than in the Commercial Code, and also became clear that there are some countries the percentage of references is high in common in both the Civil Code and the Commercial Code. In addition, this research analyzed the degree of similarity between the draft of the Civil Code and the legislative reference.
The legislative material that became clear in this research is digitalized and published on the Web. -
Political and economic research regarding oligarchy in Japan in the 20th century: a survey from the biography of former Emperor Hirohito

Grant amount：\3510000 （ Direct Cost: \2700000 、 Indirect Cost：\810000 ）
This research project, based on the information extracted from the biography of former Emperor Hirohito (Showa-Tennou-Jitsuroku), analyzes the authoritarian regime centered around the former emperor and its transformation from the Meiji to the postwar period.
(a) This research formulated text data from the Emperor's biography and extracted the name and title of the individuals who were presented at Court. As a result, we could extract the names and titles of 44,322 presentees. A look at the list reveals that Imperial Princes, Lord Keepers of the Privy Seal, and Ministers of the Imperial Household were frequently granted an audience to the former emperor. Also, we tabulated monthly data showing the number of meetings with the the former emperor by each person from 1941 to 1944 and found that this data may reveal an aspect of some historical events during the period. (b) Associated with the project (a), we built a retrieval database of the legal news (Houritsu-Shinbun). -
Legal Information Base for analyzing foreign laws in the drafting process of the Japanese Civil Code

Authorship：Principal investigator Grant type：Competitive
Grant amount：\2730000 （ Direct Cost: \2100000 、 Indirect Cost：\630000 ）
The purpose of this research is to collect foreign laws referred in the drafting process of the Japanese Civil Code, and to clarify the relationship between the Civil Code and the referred foreign laws. The research specified that the draftsmen of the Civil Code referred to 34 countries or regions and their 124 laws, and examined 119 laws of them. The analysis revealed that each field of the Civil Code was likely to refer to different countries’ laws. Based on the results, I developed and opened the WEB system that enables us to analyze the relationship between the Japanese Civil Code and foreign laws.

Grant amount：\211380000 （ Direct Cost: \162600000 、 Indirect Cost：\48780000 ）
This project focused on the legal information of Japan, China, Korea and Taiwan (CJKT) and aspired to promote mutual in-depth understanding and study of comparative law. The results are as follows. The project developed through the CJKT collaboration an information sharing environment where 140,000 bilingual pairs (the original language and English) of statutes of the CKT, the digital images of Japan's English Official Gazette and 160,000 pairs of its bilingual text, and 13,000 entries of the standard translation dictionary of legal terms of the CJKT are compiled. The project developed the approaches for machine translation and the document type definition of Japanese statutes. The project learned the practice of Korea and the EU for "plain law" and developed a model of the "LawPack," an information package to enhance the knowledge of a particular legal topic. The "eLen" system with 980,000 rules of Japanese local governments made the crossover search on the stored data possible.
