Only for complicated matters outside of our direct expertise, do we partner with Japanese experts.

What type of issues have you resolved?

We have resolved issues of strata buildings in a phased development, where Building Standard Code and Real Estate Registration Law apply. This allowed the developer to develop the project as originally intended.
In this case, we negotiated with the authorities at different levels and jurisdictions where the Town Planning Law and Building Standard Law applies and the Japanese civil engineer and architect had issues understanding the relationship between those regulations. The developer was able to avoid building unnecessary public road works.
We negotiated directly with the architect’s structural engineer to get the aesthetical outcome the client desired.
We worked with the mechanical engineering consultant to provide a solution to the onsen water supply for a land development.
