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.

MESSAGE

We will continue to engage sincerely with Infra-Sharing business and strive to create new value

To accelerate our medium- to long-term growth, we decided to strengthen our management foundation by partnering DigitalBridge Group, a leading global digital infrastructure investment company based in the United States. As a result, our shares were delisted from the Tokyo Stock Exchange Growth Market on January 7.

We would like to express our sincere gratitude to our shareholders and all our stakeholders for your continued understanding and support over the years. We are committed to further enhancing corporate value and kindly ask for your ongoing understanding and support.

Even after delisting, there will be no changes to the current management structure, and we will continue to provide stable services. Additionally, by leveraging DigitalBridge’s global industry insights and network, we aim to further enhance and innovate our services to better serve all our customers, including mobile network operators.

We will continue to maintain close communication with supervisory authorities, such as the Ministry of Internal Affairs and Communications, as well as with mobile network operators and other telecommunications companies, and further strengthen our collaboration to protect Japan's communication infrastructure and contribute to the growth of the industry.

Last year, we celebrated the 10th anniversary of our service. Over the past 10 years, we have been able to continue providing services thanks to the support of many, including the real estate developers who adopted our services, the mobile network operators using them, and the partner companies supporting operations.

We extend our deepest gratitude to everyone who believed in and supported Infra-Sharing. The year 2025 will mark a new beginning for JTOWER. We will continue to engage sincerely with Infra-Sharing business and strive to create new value.
