CARTA HD Announces Complete Subsidiary Status with NTT Docomo and Acquisition of D2C

CARTA HD Strengthens Its Position with New Industry Moves

CARTA Holdings, based in Minato, Tokyo, has made strategic advancements recently, culminating in significant structural changes within the company. On January 15, 2026, CARTA HD announced that it officially became a consolidated subsidiary of NTT Docomo, and the following day, January 16, it completed the acquisition of all shares of D2C, making it a wholly-owned subsidiary. This transition is seen as a pivotal movement in enhancing CARTA HD's capabilities in the digital marketing sector.

Becoming a Consolidated Subsidiary of NTT Docomo

The journey to becoming part of the Docomo family involved several transactions aimed at aligning business objectives. As part of its strategy to strengthen partnerships within the industry, CARTA HD undertook a stock split and acquired its own shares from Dentsu Group, a significant stakeholder in the company. With these actions, the shareholding ratio of NTT Docomo in CARTA HD surpassed 50%, thus confirming its status as a consolidated subsidiary.

This merger is expected to leverage the strengths of both companies, enhancing CARTA HD’s market position and operational efficiency. By being under the larger umbrella of NTT Docomo, CARTA aims to synchronize its strategies with those of a leading telecommunications provider and solidify its digital marketing capabilities.

Acquisition of D2C

Just a day after becoming a part of the NTT Docomo family, CARTA HD moved forward with its acquisition of D2C through a stock exchange agreement. With this agreement finalized, D2C has officially become a wholly-owned subsidiary of CARTA HD. This acquisition is set to unlock further potential in digital service offerings, expanding the customer base for CARTA HD's marketing solutions.

The implications of acquiring D2C are multifaceted; it not only consolidates CARTA HD’s offerings but also prepares the company for enhanced collaborations within the digital ecosystem. This strategic merger aims at maximizing operational synergies between CARTA HD and D2C, facilitating innovative marketing solutions to meet the evolving needs of clients.

Future Outlook

With these transformative changes, CARTA HD is well-positioned to drive growth in the digital marketing arena. As an integral part of NTT Docomo, they anticipate tapping into advanced technologies and enhancing customer engagement through D2C's established channels. This integration will allow CARTA HD to harness combined expertise, facilitating innovative marketing strategies and campaigns.

Looking ahead, the firm aims to exploit this newly formed synergy to propel the scope of its digital marketing initiatives further. By aligning resources and knowledge, CARTA HD plans not only to strengthen its market presence but also to introduce pioneering solutions that set the trend in the digital landscape.

For those interested in recent developments regarding CARTA HD, its leadership team is headed by President and Executive Officer Hideki Watanabe along with Executive Vice President and Officer Manabu Takahashi.
