Bunka Engineering = Co-create with invisible beings 

We create open environment while interacting with invisible beings such as culture, history, wind, gravity and heat.

We work on projects with a fusion of design and engineering.

We aim to create a better living environment by dealing not only with design and function issues, but also with structural and environmental issues.
