Merging the family firm’s care subsidiaries and becoming Sunwels (2011)
A form of unification that meant going under
The phrase "tidying up group companies" does not capture what the 2011 unification implied. Care Communications, which Nawashiro Akinori had started, became at this point a subsidiary of his father Nawashiro Akihiko’s architectural firm Item, bundling three scattered care companies into one. It can be described as a structure that placed his own company on the subsidiary side rather than the parent side, giving priority to efficiency of management. Precisely because he had decided to make facility operation the axis of the business, this appears to be a judgment that took unification of the business ahead of the hierarchy of capital.
That said, this unification did not guarantee the rapid growth that followed. The 2011 integration, coinciding with the opening of one facility in Kaga, went no further than a reorganization of a regional mid-sized operator. Rapid expansion had to wait for a separate move — specialization in Parkinson’s disease — and the fact that this expansion stumbled in 2025 over improper billing also remains. A reorganization that gathers businesses into one organization does not determine what will later be loaded onto it, or how it will be disciplined. Whether an organization is well or badly made may only show at the stage where the quality of what is poured into it is put to the question.
