ExaWizards Inc. and NTT DOCOMO BUILDING INC. have jointly developed a “closed AI agent” that allows for the secure use of important corporate data in a dedicated environment, and will begin offering it from August 17, 2026.
The overview and features of this environment are as follows:
A secure execution environment dedicated to the customer
Customers can access a dedicated environment via a closed network, allowing them to securely utilize AI agents that leverage sensitive data such as design drawings, technical documents, contract information, and customer information. By employing dedicated GPUs and a Kubernetes architecture, stable processing performance and high security are achieved without taking data outside the network.
Development environment for realizing industry- and business-specific AI agents
By utilizing the AI agent templates provided by “exaBase Studio” and the industry- and business-specific AI agents provided by NTT Docomo Business, you can efficiently develop AI agents of a quality that can be integrated into business processes.

NTT Corporation’s large-scale language model (LLM) “tsuzumi 2” and open-source LLMs can be executed in a customer-specific environment, and business data and prompts are never sent to external AI services. Furthermore, with the on-premise version, everything from hardware to LLM and AI agents can be operated entirely within the customer’s own environment in Japan, providing a sovereign AI-enabled environment that ensures sovereignty over data and the AI infrastructure.
Infrastructure operation and maintenance will be provided by NTT Docomo Business.
NTT DOCOMO Business handles everything from building the dedicated environment to operation, maintenance, and security management, allowing customers to focus on introducing and utilizing AI agents without having to build their own cloud or AI infrastructure operation system.
