Japan: Weekly Aggregated Political Violence and Demonstration Events

The Armed Conflict Location & Event Data Project (ACLED) provides weekly aggregated counts of political violence, civilian-targeting, and demonstration events in Japan. The data is organized into country-year and country-month summaries to track longitudinal trends in civil unrest. This dataset was last updated in March 2026 and is delivered in XLSX format.

Use Cases

• Analyzing the frequency of 'demonstration events' to identify periods of heightened civil unrest in Japan
• Correlating 'political violence' counts with national policy changes or economic shifts over 'country-year' periods
• Monitoring 'civilian-targeting' trends to assess changes in the domestic security environment

Strengths

• Weekly update frequency provides near real-time monitoring of political stability
• Sourced from ACLED, a specialized authority in conflict and event monitoring
• Categorized by specific event types including political violence and civilian-targeting

Limitations

• Aggregated format prevents granular spatial analysis of specific incident locations
• Full event-level data is gated behind a separate registration process on the ACLED website
• Lack of raw event descriptions limits qualitative research
