AboutAbout the lab
Researching community development by practicing it
The Machizukuri Lab studies methods of design, planning, and management for regenerating communities and towns.
The lab coordinates its own community development projects and builds up its practice-based research through them.
The lab's central activity is to explore methodologies, techniques, and the basic theories that support them from many angles, and to apply them to real community development efforts.
Students interested in applying technologies such as spatial design and GIS to community development, or in theoretical research, are also welcome.
