Japan Daily Port Activity and Estimated Shipment Volumes in Metric Tons

PortWatch provides daily port call counts and shipment volume estimates in metric tons for maritime hubs across Japan. This time-series data, updated through March 2026, tracks both incoming and outgoing trade flows at the port level. The dataset is delivered in CSV format for analysis of Japanese maritime logistics.

Use Cases

• Analyzing daily fluctuations in Japanese maritime traffic using port call counts
• Forecasting logistics demand based on incoming shipment volume estimates in metric tons
• Correlating outgoing shipment volumes with national economic performance indicators

Strengths

• Daily temporal resolution for tracking short-term trade fluctuations
• Provides both frequency (port calls) and capacity (metric tons) metrics
• Maintained by PortWatch, a specialized maritime monitoring organization

Limitations

• Shipment volumes are estimates rather than primary customs records
• Geographic scope is limited strictly to Japan
• Specific column headers and row counts are not explicitly defined in metadata
