Our Difference – KOYO Inc.

We, at KOYO, have been supporting real estate investment for many years as a special agent of our clients based on our customers’ special demands. We are clearly different from Japanese real estate investment companies that introduce real estate not popular in Japan via a website that anyone can view at any time.

For many years, KOYO has been led by a president and has obtained attractive real estate investment information that is transmitted secretly through financial institutions, wealthy routes and so on. In addition to introducing the confidential information to customers, we purchase them and operate and manage in-house. We have stable real estate investment because we make the investment forecast focusing on the problems that occur after the investment and the resale profit in the near future at the consideration stage of the real estate investment by accumulating a lot of experiences of real estate operation and management over many years.

We assist your real estate investment as your special agent based on your special demands. It is different from a company that sells real estate purchased by the company or real estate not popular in Japan via a website that anyone can view anytime.

Even with seemingly attractive investment properties, there are some pitfalls that can always be said. Also, properties that attract many investors are highly competitive and it is difficult to invest at a reasonable price. In other word, if you can find a property that is not attractive at first glance but in fact it has an unrealized gains, it is likely to be able to invest at a reasonable price. If such an investment succeeds, the monthly balance will be stable and attractive, and in the future there will be higher hopes for attractive capital gain.

For achieving the stable profitability of the invested real estate with the low vacancy rates and maximize the real estate value, both the supporting ability of existing tenants and leasing ability of new tenants are important.Especially in the case of building management where there are many competitors of similar grade, the building manager is required both the abilities to communicate with multinational tenants and to respond flexibly to tenant needs, such as increased floor space demand and assist of human resources.

We won the “1st place in Japan in the Building Management Award 2018″ as a result of a national vote sponsored by the Building Management Research Institute, regarding “UENO KOA Building” owned and managed by our company based on the concept of “Neighbor Love”.

Based on these years of experience in real estate operation and management, we will support the Japanese real estate investing for achieving not only stable operation and management but also further business growth of real estate investment for overseas customers.
