Company Information

Who we are

HQ : Kofu city, Yamanashi
Established : 1966
Employees : 177

It takes less than two hours by train from Tokyo, the capital of Japan.
It has been 57 years since we started our business in 1966 in Yamanashi Prefecture, surrounded by beautiful water, abundant nature and world-class fruits including the world heritage Mount Fuji.

Under the coherent philosophy of “Creating value for society through the use of computers,” we have grown and developed year after year, adapting to the environment like an aging large tree.

While focusing on the development and implementation services of medical and administrative systems, which we have specialized in since our founding, in recent years we have started a new in-house package development business. One example of this is the development of the “INCLSS Developmental and Educational Support System,” which enables the government to provide seamless support to children who need support due to developmental disabilities through life stages. The system is being used to provide various local government services.

With the fast-moving practical application of the maglev Shinkansen and the hydrogen and fuel cell industries being promoted by Yamanashi Prefecture, we are honing our talents and putting our best performance to work to create a “Prosperous society where each and every one of us hones their talents and puts out their best performances, giving them a reason for living and working.”

Our vision

Our services/products

・ The product of our company is “human resources”.
We provide our own services to our customers, and our services become products.

・Developing systems that leverage our strengths
INCLSS (Inclusive Continuous Life Stage Support)
The Developmental and Educational Support System is a system that provides integrated management of growth records, mainly in the form of “Individual Support Plans,” for children who need support due to developmental disabilities and shares them with relevant organizations. We fully assist the “seamless support” system, required by government agencies, for individual children. We received more inquiries from across the country, and we have finally started the implementation on a full scale.

Message from our employees from abroad

My name is Hayakawa, and I am on my sixth year with the company. I came to Japan after graduating from university in the Philippines. At first, I had trouble with Japanese, but thanks to my fellow colleagues who happily taught me Japanese, I became able to read and write Kanji characters without any problems. Now, I write design documents and review junior employees, and it has become routine for me to go to customers by myself. I recommend Japanese animation for studying Japanese culture and language!
After joining the company, you will work with me. Let’s work on it together.

There are also several club activities in the company. It’s not essential, but you can join your favorite club and work out with your boss and coworkers after work and on holidays to eliminate the lack of daily exercise.
