Introducing the Warring-States Japan Battle Data

This article introduces the “Warring-States Japan Battle Data,” a new data set covering 2,889 battles occurring within Japan during its warring-states period, from 1467 to 1600. The dataset contains fifteen variables covering various features of the battles, including the date, location, participants, initiators, and victors, among others. This article introduces the sources of the data, describes the collection procedures and coding rules, presents basic descriptive statistics of key variables of interest, and applies the battle data to an important question in the political violence and international relations literature: whether conflict “contagiously” diffuses across time and space. The data introduced here should be of interest to scholars of international relations, civil conflict, Early Modern East Asia, and Japanese history, among others.

本文介绍了「日本战国战役数据集（Warring-States Japan Battle Data）」——一套覆盖1467年至1600年日本战国时期境内2889场战役的全新数据集。该数据集包含15项变量，涵盖战役的多维度特征，包括作战日期、地理位置、参战主体、发起方与获胜方等。本文阐述了该数据集的来源、数据收集流程与编码规则，展示了核心关注变量的基础描述性统计结果，并将这套战役数据集应用于政治暴力与国际关系研究领域的一个重要议题：冲突是否会在时空维度上发生传染性扩散。本文所呈现的这套数据集，将为国际关系、国内冲突、近代早期东亚研究以及日本史等领域的学者提供研究参考价值。
