Notice of Company Name Change (Econosys Design → MON)

As of February 1, 2026, Econosys Design Co., Ltd. has officially changed its name to MON Inc.

“Econosys” was originally the name of a band I formed with Kato-san.
When I began working as a student in 2002, it was less a formal entrepreneurial launch and more a natural progression.
I adopted the name as it was, and for the past 24 years we have operated as “Econosys Design.”


Marking the 10th anniversary of our incorporation on February 1, we have decided to unify our company name under “MON.”

There are several reasons for this change.
One significant factor is that since opening MON Gallery & Wine Bar in 2023, we have increasingly been recognized as “MON.”
We feel this momentum will continue to grow in the years ahead.

In addition, we are currently planning a private rental accommodation facility on the lot north of our office.
This project will also operate under the name “MON” and, like the gallery and wine bar, will be developed as a space that embodies and expands the world of MON.

Please note that while our company name has changed, there will be no changes to the content or structure of our design business.
Including myself, our directors and employees will continue our work as before.

We sincerely appreciate your continued support.

MON Inc.
