On top of safety, we will offer a comfortable life with our condominium management to have more smiles on customers’ faces.

Providing sincere service for your privately owned space, as well as the management of common-use space to enhance customer satisfaction

This summarizes the overview of Life Port Seiyo, a condominium management company. There are so many different issues to be taken care of with condominium management because each resident has his/her own standard of comfort.

In other words, there does not exist an absolute reality but as many realities as the number of residents, each of whom has their own happiness and anxiety. A number of different people are living side-by-side in one building.

Therefore, we put our priority on resolving residents’ concerns due to living in a housing complex as many as possible, not to mention strengthening safety so they can live comfortably. Our strongest desire is to have our customers smile more.
