Bunka Engineering = Co-create with invisible beings 

We create living environments while co-creating with invisible beings such as culture, history, climate, and community. To that end, we work on projects by fusing design and engineering. By transcending the boundaries of time and space, and co-creating with beings which are there but cannot be seen, we aim to maximize the potential of a place and create better living environments.
