Road Network of Japan from OpenStreetMap with Surface and Lane Attributes

Japan's road network data, extracted from OpenStreetMap where the 'highway' tag is present. The dataset includes features such as road names, surface type, smoothness, width, lanes, and one-way designation. It is provided by the Humanitarian OpenStreetMap Team and was last updated on 2026-03-03.

Use Cases

• Route planning and network analysis based on road connectivity and oneway attributes.
• Assessing road infrastructure quality based on surface and smoothness attributes.
• Mapping road names and multilingual labels based on name, name:en, and name:ja fields.

Strengths

• Includes multiple physical road attributes such as surface, width, lanes, and bridge status.
• Provides multilingual road naming with fields for English (name:en) and Japanese (name:ja).
• Available in multiple geospatial file formats including SHP, GEOJSON, GEOPACKAGE, and KML.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Freshness should be verified as the last update date is 2026-03-03.
