JTOWER’S VISION

Infra-Sharing Services from Japan
Lead the World

Japan is behind in the field of global telecommunications infrastructure sharing.

In 2012, when the term “Infra-Sharing”
was not common in Japan, we launched our first business.

Our goal is not the same as other global tower companies;
our goal is what they have never done.

Meeting the world’s highest standard for network quality as required in the Japanese telecommunications industry, we will overcome challenges and improve services.

We will treat all stakeholders with respect and honesty, including mobile network operators, real-estate developers, and partner companies,

We will continue to innovate and challenge new ideas to expand business globally.

We will pursue the world’s state-of-the-art technologies, services, and business models.

As a result of these efforts,
we will make the Infra-Sharing services that we provide global standards
and create our future through businesses expansion.

This is the vision of our company.
