Ministry of Land, Infrastructure, Transport and Tourism


A project led by Japan’s MLIT: Ministry of Land, Infrastructure, Transport and Tourism to develop and open data on 3D city models throughout Japan.
The project aims to make urban policy sustainable, human-centric, and agile through the development of 3D city models, use cases, and promotion of their use. The goal is not just to digitize the city, but to realize digital transformation (DX) of urban policy.

There are three main aims of the project:

  1. Creation of new solutions using existing data. Our 3D city models are developed by reusing the basic maps for urban planning, the map is created by the local governments regularly, so we realize a data development methodology that is reasonable and scalable.
  2. Enhance data ecosystem of developing 3D city models and creating use cases.
    We are not only focusing on data development, but also on data utilization. Data by itself does not create value, so we emphasize providing 3D city models to the market for generating innovation and new business.
  3. Open format, open source, vendor-free. We have adopted OGC CityGML2.0 as the standard specification for 3D City Models in Japan, because the open format can be used by anyone, at that, we provide the source code for various software for 3D City Models as open. System engineers and other professionals play a key role in creating innovations using data, so we make efforts to create easy environment for system developers to use data by promoting projects as openly as possible.


This project was made possible by the flat and cross-sectoral collaboration of experts from a wide range of fields, including the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), the study and development of data specifications for 3D city models, the creation of use cases, and the dissemination of information.


Ministry of Land, Infrastructure, Transport and Tourism (JP) It is one of the administrative organs in Japan that is responsible for the comprehensive and systematic use, development, and conservation of national land, the harmonious development of social infrastructure, the promotion of transportation policy, meteorological services, and maritime safety and security. The City Bureau, which promotes PLATEAU, is an internal department established in 2011 that is responsible for urban renewal, community development, and regional development.
