SoftBank Forges Japanese AI Alliance to Challenge US and China

SoftBank, NEC, Sony, Honda form consortium to develop a trillion-parameter AI model for robotics and industry, reducing reliance on foreign tech with major state funding.

A powerful consortium of Japan's corporate titans has been unveiled, aiming to secure the nation's technological sovereignty in artificial intelligence. Led by SoftBank Group, the alliance includes NEC, Honda Motor, and Sony as founding partners, each holding stakes in the upper double-digit percentage range. Their newly formed entity, "Nihon AI Foundation Model Development," will focus on developing a massive, domestically controlled AI model to reduce reliance on American and Chinese technology providers.

The venture's strategy extends beyond software, targeting what it terms "physical AI." This involves integrating advanced AI models directly into hardware like industrial robots and autonomous systems. SoftBank and NEC will spearhead development of the underlying foundation model, while Sony and Honda will drive practical applications in robotics and mobility. The initial technical goal is a large language model with approximately one trillion parameters, optimized specifically for Japanese business environments.

Financial and industrial heavyweights have joined to back the ambitious plan. Strategic investors include steelmakers Nippon Steel and Kobe Steel, alongside the country's three megabanks: MUFG, SMBC, and Mizuho. To manage the enormous development costs, the consortium is preparing an application for state subsidies. It seeks up to one trillion yen, equivalent to roughly $6.3 billion, from the government agency NEDO, with funds to be disbursed over a five-year period starting in fiscal 2026.

Operational leadership will fall to a SoftBank manager, with a starting team of about 100 specialized AI engineers. The group also plans to incorporate technical expertise from Preferred Networks. By 2030, the alliance aims for market leadership in robot-integrated intelligence, deploying its models in hardware-intensive sectors such as automotive manufacturing, factory robotics, gaming, and semiconductor production.

This national initiative coincides with a broader restructuring of SoftBank's global operations. Reports indicate Rene Haas, the head of chip-design unit Arm, is poised to take on leadership of large parts of SoftBank's international business. This move is expected to better align software ambitions with the group's in-house AI chip strategy, known as "Project Izanagi." The foundation models developed in Japan will be made available to participating firms, fostering a domestic ecosystem for advanced automation.

The launch expands SoftBank's existing AI portfolio, which already features an 11% stake in OpenAI and massive investments through its Vision Fund 2. The combination of global chip architecture via Arm and a heavily subsidized national software ecosystem positions the conglomerate as a vertically integrated player in the emerging cycle of hardware-driven AI. With Japanese markets closed on Sunday, the reaction from SoftBank shareholders will become clear at the start of the new trading week.
