SoftBank and OpenAI Form Joint Venture in Japan

The joint venture’s moniker may be dull, but the AI solution’s name isn’t.

SoftBank and OpenAI have teamed up for the creation of a new JV, SB OAI Japan GK, which will introduce an AI solution called “Crystal intelligence” to the Japanese market.

The initiative is aimed at companies in Japan and how they manage operations and strategy. The idea is to integrate AI at scale into corporate management.

“With the launch of SB OAI Japan, AI agents will understand our goals and collaborate with each other to autonomously carry out tasks we want them to perform,” said Masayoshi Son, Chairman & CEO of SoftBank.

What “Crystal Intelligence” means

Crystal intelligence is as an enterprise AI suite combining OpenAI’s latest technologies — including language models and task-specific GPTs — with customized implementation and integration support from SoftBank.

It will offer Japanese companies a way to embed AI directly into their business operations, from management decision-making to productivity enhancement and innovation cycles.

By automating routine tasks and facilitating data-driven decision-making, Crystal intelligence aims to help executives and employees focus on higher-level goals. The solution also includes localized support, which is expected to be crucial for adoption across Japan’s highly structured corporate environment.

SoftBank as the first test case

Before bringing Crystal intelligence to the wider market, SoftBank will be the first to adopt and deploy the technology internally. This early rollout will serve as a proof-of-concept to validate its effectiveness in real-world corporate settings.

Insights gained from SoftBank’s own use — including lessons on workflow integration, AI governance, and change management — will be shared with other companies through SB OAI Japan.

This approach aligns with SoftBank’s broader goal of becoming an AI-native organization. The company has already built around 2.5 million custom GPTs for internal use.

Japan’s digital economy

SoftBank says that despite being a technology leader, Japan has faced challenges in adopting AI widely across traditional industries.

With SoftBank’s local influence and OpenAI’s technological expertise, the joint venture could serve as a catalyst for modernization, helping Japanese firms close the digital transformation gap with their Western counterparts.

If successful, Crystal intelligence could redefine corporate hierarchies, labor practices, and productivity norms in Japan — particularly in sectors such as manufacturing, finance, and telecommunications, where automation and data utilization are seen as key to maintaining competitiveness.

There isn’t complete harmony in Japan. The nation’s leading anime and game studios are pushing back against OpenAI. They accuse the company’s video model Sora 2 of using Japanese works without consent.
