About Us

We, OTAK JAPAN Inc., perform Construction Management / Project Management (CM/PM) services for construction projects as a core business. We were established in 2015 to realize the maximum value for the Owner by performing reliable management services at all stages of the construction production system.

In addition, design and engineering company OTAK in the United States and No. 1 CM/PM company HanmiGlobal in South Korea are our investment companies, and we have global operating systems established by Japan, the United States and South Korea.


In the period of “Reiwa,” even though the Tokyo 2020 Olympic and Paralympic Games have been postponed for 1 year due to the Covid-19, the construction industry will continue to be busy due to the improvement of tourism infrastructure, preparation for the Osaka Expo, and the construction of integrated resorts with casino space at several locations in Japan.

However, a society with a declining birthrate and an aging population has certainly arrived, and it is easy to imagine the trend of the industry moving from new construction to stock utilization renewal, and from domestic to overseas. As the overseas business expansion is essential, though the scars from a few years ago are fresh in our memory.

We believe, despite difficulties, that we are confronting opportunities of innovation in the next 10 years. In this light, we endeavor to establish a more productive construction system in Japan, and to contribute to clients, industries and societies in the long run.


Based on accumulative knowledge, data and expertise, we will accomplish our tasks with utmost sincerity in order to produce the best outcomes and to win trust and confidence in clients and all stakeholders, including designers, constructors and contractors.


In addition to our core CM/PM business, we intend to contribute to society by challenging new businesses around the construction industry with key words such as environment, energy, and aging society.


We will appreciate your help and encouragement.
