- The platform operates through SB OAI Japan, a collaborative venture equally owned by SoftBank and OpenAI established in late 2024
- Masayoshi Son, SoftBank’s CEO, characterized Japan’s cyber vulnerability as critical, positioning the initiative as essential national protection

SoftBank Group introduced a cutting-edge cybersecurity platform in Tokyo this Tuesday, leveraging OpenAI’s artificial intelligence capabilities to strengthen Japanese enterprises against mounting cyber threats.
Dubbed “Patching as a Service,” the solution focuses on Japan’s 3,000 largest corporations managing essential infrastructure — including aviation hubs, energy grids, and transit systems.
Deployment occurs via SB OAI Japan, the equally-shared partnership between SoftBank Corp and OpenAI established last November. This collaboration was designed to build and exclusively distribute AI-powered solutions throughout Japan.
Masayoshi Son delivered a stark warning about the severity of current risks. He likened Japan’s cybersecurity readiness to defending against modern weaponry with outdated tools.
“We want to create a system where we will be able to defend critical Japanese infrastructure,” Son stated during the Tokyo announcement.
“I feel it is our duty,” he emphasized.
Platform Functionality
The solution operates through a dual-phase approach: initially identifying system vulnerabilities, followed by determining necessary security updates. Son consistently labeled cyber adversaries as “the bad guys” during his remarks.
SoftBank Corp CEO Junichi Miyakawa revealed that approximately 50 staff members currently support the deployment, with expansion plans targeting 1,000 employees.
OpenAI CEO Sam Altman was originally planned to attend physically but participated through a brief video message instead. He cited a personal reason for his absence — the unexpected early arrival of his daughter. OpenAI’s Chief Research Officer Mark Chen represented the company on-site.
SoftBank’s Substantial OpenAI Partnership
SoftBank ranks among OpenAI’s most significant financial backers. The company’s total committed capital to OpenAI amounts to $64.6 billion through 2026.
This cybersecurity platform represents the newest development in an expanding collaboration. Since establishing SB OAI Japan last year, both organizations have focused on creating AI integration solutions tailored for Japanese businesses.
Recent developments saw the U.S. administration restrict foreign access to Anthropic’s Fable 5 and Mythos 5 systems last week, referencing national security justifications — highlighting the increasingly restrictive environment surrounding AI and security worldwide.
Both SoftBank Corp (9434.T) and SoftBank Group (9984.T) were represented at Tuesday’s corporate presentation in Tokyo.
