About Dayz

Our developer- and
user-first stance
supports all users

We began in 2008 as a developer agency supporting the generation of profits from software developed and owned by third parties. Utilizing the knowledge and experience we have gained since then, we are rolling out and operating software and services developed on our own.
From our base in Nihonbashi, at the center of Tokyo, we reliably and continually provide products and services demanded by users, with "Made in Japan" safety and peace of mind.

Giving form to desires, needs, and ambitions

All of our services are developed by our developers themselves from ideas and skills drawn from program languages and architectures, and from the comments and wishes of customers. This is because we believe that the experiences and viewpoints of the people who engage with and touch our services are key assets. Toward that end, at Dayz we have prepared an environment that offers places and opportunities for all engineers to communicate their own ideas and to take up the challenge of creating their own work.

We leverage the knowledge and experience gained through our original development and services, along with our relationships with trusted clients and partners, to engage in business as a developer agency that supports profit generation, development, analysis/statistics, and press releases/PR for software owned by individual and enterprise developers.
