What's New? 

National-scale 3D building coverage (LOD2)

Cityweft now includes ~26.8 million buildings across 266 datasets, making it one of the most comprehensive collections of LOD2 3D building data in Japan.

Each building includes:

• accurate roof geometry

• reliable building heights

• detailed building footprints

This allows you to generate high-quality 3D urban context models across Japan.

Largest datasets available

The platform includes high-density building coverage in major cities:

• Yokohama: ~883K buildings

• Nagoya: ~738K buildings

• Sapporo: ~629K buildings

• Osaka: ~616K buildings

• Okayama: ~521K buildings

• Kyoto: ~511K buildings

• Saitama: ~495K buildings

• Sendai: ~418K buildings

• Niigata: ~407K buildings

• Hiroshima: ~370K buildings

Higher-fidelity urban context

Compared with simple building extrusions, the LOD2 dataset provides:

• realistic roof shapes

• improved building height accuracy

• more detailed urban massing

This makes the dataset ideal for:

• architectural design

• planning studies

• energy and solar analysis

• visualization

• digital twin models

Available across all Cityweft workflows

The Japan building dataset is available across the full Cityweft ecosystem:

• Cityweft web platform

…and export directly to your modeling software.

How the data is prepared in Cityweft

Japan’s geospatial data is published by multiple national and municipal sources, meaning datasets vary in:

• format

• structure

• modeling standards

• update cycles
  

Cityweft harmonizes these datasets using a standardized processing pipeline that:

• aggregates 266 datasets into a unified system

• cleans and validates geometry

• optimizes buildings for fast 3D performance

• standardizes coordinate systems

• preserves attribution metadata
  

The result is a clean, unified LOD2 building dataset for Japan, ready for immediate use.

Who is this for?

Architects: Competitions, early massing, site context, and client visuals

Urban planners: Density studies, zoning analysis, and planning proposals

Engineers: Solar analysis, environmental simulations, infrastructure planning

Real estate developers: Feasibility studies and stakeholder communication
