MESSAGE
We are dedicated to strengthening our capabilities to uphold
Japan's telecommunications infrastructure
Fiscal year 2025 marks a new beginning for JTOWER under our new organizational structure. While continuing to provide continuous and stable services, we will also make proactive investments to strengthen our structure with an eye toward the future.
Our initial focus will be on capital investments.
In recent years, we have seen a growing demand for the replacement of 4G in-building networks, which were historically developed independently by mobile network operators, with Infra-Sharing during equipment upgrade cycles.
Furthermore, from a medium-to-long-term perspective, we will proceed with the acquisition of additional towers to promote Tower Sharing, and expand our service to provide greater utilization benefits for mobile network operators.
Next, we will invest in technological development.
JTOWER's strength lies in our in-house technology development. Moving forward, in addition to adopting Open RAN, we will contribute to the further advancement of Infra-Sharing by expanding the areas where sharing is feasible.
Finally, we place a strong emphasis on investing in our human resources to reinforce these growth strategies.
In addition to enhancing recruitment activities, we will prioritize improvements to the working environment, training systems, and compensation.
In Japan's telecommunications industry, the competitive focus is rapidly shifting from network development to a wide range of services including AI, finance, and DX (Digital Transformation).
Amidst this shift, telecommunications infrastructure is being positioned as a collaborative area, and efficiency improvements are expected to accelerate. Furthermore, collaboration among mobile network operators is increasingly, including the establishment of cooperative frameworks for swift network recovery in response to increasingly severe natural disasters.
Looking further ahead, as Japan's population continues to decline, the question of how to maintain and operate our telecommunications infrastructure will become an increasingly prominent social issue.
In this context, it is becoming increasingly clear that the streamlining of both indoor and outdoor network development, as well as the maintenance and operation of telecommunications infrastructure, through Infra-Sharing is unavoidable.
We believe that the presence of Infra-Sharing providers, equipped with robust capabilities and advanced technical expertise, is essential for the advancement of Japan's telecommunications industry.
With a forward-looking perspective, JTOWER is committed to enhancing its structure, upholding our resolve and responsibility to support Japan's telecommunications infrastructure.
