About us
Paradise Ware Inc.

In the past, the mammoth was hunted for food and clothing.
Such tasks were made possible by the cooperation of individuals combining their strengths and working together.

In the modern age, technology has advanced dramatically, but the world is still facing many grave problems, such as economic recession, poverty, intense corporate competition, and increasing concerns over welfare, environmental issues, international conflict and terrorism.

As with small scale issues, like organizing the next work function, or a wedding ceremony, the key to resolving these large scale issues is human cooperation.

We firmly believe in the power of human cooperation, to aid in the management of all things.

The guiding principle of all humankind, from the age of the mammoth, to the modern age of technology, is the determination of people and the spirit of cooperation.

What is our aim of “paradise”?

The challenge of bringing new value to the world is a lofty one, but we must continue on this path and face the many difficulties and obstacles that befall us with strict resolve.

Our CEO Masayoshi Hashimoto has over 18 years of experience in project management, having been involved in the success and failure of over 300 projects. He has witnessed many projects collapse due to failures of management, despite great ideas, talent, and ample budgets. He is well aware of the reality of such project failures, as are the other members of our team.

With this experience, we believe we can make the world a better place, by lessening the problems of project management if only by a small amount.

After over four years of development we are proud to offer the new project management tool: Mammoth Project.

Please try our software, and if it suits your goals, let us aid you in the success of your project.

A world where everyone can make their ideas a reality and create new value for all humankind.

This is our dream, our aim of “paradise”.
