Sotsu, Inc. provides clients with assistance to convey their thoughts through the development of software programs in various fields. The core members of Sotsu have more than 15 years of production experience in the game industry.

They have engaged in uncompromising development at major publishers and developers, thinking about things from the client’s perspective.

The development concept at Sotsu is “efficient development without deviation.” We believe that the safe progress of projects without deviation translates into results that deepen our relationship of trust with our clients.

Our corporate business strategy is based on four concepts.

The first is thorough progress management.
In all processes of the project, from planning and design to implementation, we engage in thorough progress control based on quantitative data in order to prevent trouble before it occurs and promote efficient development.

The second is project proposals for our clients.
Our development team is comprised of experienced UI/UX designers, planners and programmers. They have received high marks for always making content and UI proposals from the user/player perspective.

The third is to be a group of technical experts.
The core members have studied the mechanisms and transitions of programming technology over the course of many years through the development of game programs.

Technology is absorbed with much curiosity, and the good and the bad is weighed objectively with logical thinking to deliver the best plan to the client.

The last is video production to convey our clients’ thoughts.
With our technology, we engage in video production using computer graphics to propose our client’s image as a total solution service.
