Mizuho SBI Net Bank Announces Parent Company Transition to Docomo Financial Group

Mizuho SBI Net Bank Transitions to a New Parent Company



In a significant move within the banking landscape, Mizuho SBI Net Bank, headquartered in Minato, Tokyo, has announced plans for a transformative change in its corporate structure. Starting July 1, 2026, this modern banking institution will shift its parent company from NTT Docomo to the newly formed Docomo Financial Group. This announcement, spearheaded by President and CEO Noriyuki Maruyama, marks a pivotal moment in the bank's growth trajectory and operational strategy.

The restructuring is primarily aimed at adapting swiftly and efficiently to the changing business environment in the financial domain. This strategic move underscores Mizuho SBI Net Bank's commitment to enhancing its governance framework in response to potential financial risks, paving the way for sustainable growth and innovation.

Overview of the Changes in Shareholding Structure

  • - Location: Nagatacho 2-11-1, Chiyoda, Tokyo
  • - Capital: 949.68 billion yen

With the upcoming transition, NTT Docomo will no longer be the parent company or largest shareholder of Mizuho SBI Net Bank starting from the set date. Previously, NTT Docomo held a commanding 50% share of voting rights, which positioned it as the leading stakeholder in the bank.

Post-transition, Docomo Financial Group will assume its role as the primary stakeholder with a significant 50% share of voting rights, establishing itself firmly in the banking arena. This strategic realignment not only reflects a reorganization in capital structure but also signals the intent of both NTT and its financial arm to enhance service offerings and customer interactions.

Focus on Customer-Centric Innovations



Under the new Docomo Financial Group framework, Mizuho SBI Net Bank is poised to drive greater integration of its services with offerings such as dPoints and dCards. Collaborations with other financial entities, like Monex Securities, are also part of the company’s strategy to provide innovative banking solutions tailored to meet the diverse needs of its customers. By continuing to cater to individual preferences, Mizuho SBI aims to unlock new opportunities in financial product development, ensuring a holistic approach to customer satisfaction and financial stewardship.

The changes are subject to the approval of relevant authorities, and stakeholders can find more details on the formal announcement made by Docomo on March 31, 2026, regarding this significant business transformation.
