Summary With the objective of understanding the entire process of a civil dispute, the specially promoted research on “Dispute Resolution and Civil Justice in the Legalizing Society” divided the process into three sub-processes and conducted one national survey for each. The three surveys were the “Disputing Behavior Survey,” which focused on the stage between the problem and the dispute, the “Legal Advice Seeking Behavior Survey,” which focused on the stage of legal advice-seeking behavior for problem-solving, and the “Litigation Behavior Survey,” which focused on the stage of litigation behavior after the lawsuit is filed.

This is the “Litigation Behavior Survey.” The “Disputing Behavior Survey” and the “Legal Advice Seeking Behavior” were published under survey numbers 1039 and 1040 respectively.

This survey is the combination of four surveys: “Civil Litigation National Survey/Case Record Survey,” “Nationwide Civil Litigation Parties and Their Lawyers Survey,” “Nationwide Civil Litigation General Public Survey,” and “Internet Survey.”

The party survey in the “Nationwide Civil Litigation Parties and Their Lawyers” comprises four types of questionnaires: “Plaintiff with a lawyer,” “Defendant with a lawyer,” “Self-represented plaintiff,” and “Self-represented defendant.” The lawyer survey comprises two types of questionnaires: “Plaintiff’s lawyer” and “Defendant’s lawyer.”

Further, in the “Nationwide civil litigation General Public Survey,” two types of questionnaires are used: General A, which uses the simple term “Trial,” as does the party survey, and General B, which uses the term “Civil Trial.”

The “Internet Survey” uses twelve types of questionnaires.

Allocation method
[Internet Survey]
With a target of 100 responses for each of the 12 types of questionnaires, the number of responses was allocated by the gender and generation in proportion to the total population. From the registered monitors (approximately 68,000 people), the survey company randomly sampled a number of people according to the number of responses received above, separated by gender and generation. Then, it asked the respondents to answer the survey on a dedicated homepage and received the answers until the allocated number was reached.
Mode of Data Collection Self-administered questionnaire: Paper
Self-administered questionnaire: Web-based (CAWI)
[Case Record Survey]
A total of 1,132 case records were randomly sampled from cases concluded in 50 district court headquarters across the country between January 1 and December 31, 2004. These samples were inspected, and the necessary items were transcribed using specially-developed computer software.

[Survey with Parties and Their Lawyers]
A questionnaire survey was conducted with the natural-person parties and lawyers in the 1,132 cases inspected in the Case Record Survey (self-administered survey (placement method) for the parties and mail survey for the lawyers).

A survey with a questionnaire with the same content as that of the questionnaire in the Survey with Parties was conducted (self-administered survey (placement method)).
