Group Synergies

In the near and far reaches surrounding the Earth, countless celestial bodies whiz through space. The Mainami Group comprises 8 companies encompassing 6 lines of business. Like the planets revolving around the Earth, the Group companies revolve around Mainami Holdings. Sometimes in opposition, sometimes in tandem, the Mainami Group companies create a galaxy of opportunities.

No form is perfect forever, however. Our operations continue to evolve and change in response to outside forces. It is imperative that we nurture existing operations while promoting promising business ventures to ensure growth.

The Group is expanding into more open markets and opportunities, moving out from Japan to other parts of Asia and beyond. As we prepare for a vibrant future, we are leveraging the teamwork within the Group to establish a substantially greater presence. Ten can become the power of 20. We call it Mainami Synergy.
