Access the above website and click on 'Tokyo Digital Twin 3D Viewer (beta version).'

The Tokyo Digital Twin 3D Viewer will open. Click 'Agree'.

The map and 3D data of buildings are displayed. This time, we were able to access data for Shinjuku Ward. You can move the camera position by dragging the mouse. You can also change the camera direction by holding down Ctrl and dragging.

You can change the display settings of the flat map from 'Map Settings' in the upper right.

By switching the “Shadow” setting on the left to “Cast and Receive,” a shadow will be cast on the 3D model.

Switching to 'Textured' applied texture to the building's surfaces, making them look more realistic.

You can add the published point cloud data by selecting 'Point Cloud Data' from 'Add Data' and choosing the data for the ward you want to view.

For example, the point cloud data for

the Tokyo Metropolitan Government area looks like this.

You can also view various other maps, such as

a real-time map of Tokyo bus routes .

The published data is as follows. The source code for the beta version of the Tokyo Metropolitan Government Digital Twin 3D Viewer is available on

GitHub . In addition, to promote the use of 3D city models, and to encourage the use of CityJSON in the Japanese developer community, the Japanese manual for the CityGML to CityJSON converter is also available on GitHub .
