Japan is in talks with Anthropic, the artificial intelligence (AI) firm behind Claude, to gain access to its new Mythos AI model, government sources confirmed this week. Japanese authorities are seeking to use Mythos to bolster national cyber defenses, particularly against threats linked to China and Russia. Officials are also seeking greater expertise in AI development as concerns over AI-related cyberattacks grow worldwide.

Sources said Japan sees securing access to advanced AI systems as a national priority as more powerful models continue to emerge. The country is already preparing the necessary systems needed to deploy the Mythos AI model if access is granted.
Japanese officials and Anthropic are expected to meet soon to push the talks forward. On Tuesday, Prime Minister Sanae Takaichi ordered a cabinet-level review of Japan’s cyber strategy. She also directed the cybersecurity minister, Hisashi Matsumoto, to assess whether government systems can detect and fix flaws.
In addition, he was tasked with drafting a plan to help critical system operators strengthen their defenses. Matsumoto said in a press conference after the Cabinet meeting that Japan is “exchanging views with the United States” over talks to gain access to Mythos.
Japan Moves Fast as Mythos Cybersecurity Risks Grow
Anthropic unveiled Mythos in April and limited access to several tech firms, including Google (GOOGL), Apple (AAPL), and Nvidia (NVDA), as well as some financial institutions like JPMorgan (JPM) and Goldman Sachs (GS).
The company said the model can detect weaknesses in web browsers and software so well that experts warn it could be misused by bad actors to disrupt systems across many sectors. It has also found thousands of flaws in Microsoft (MSFT) and Palo Alto Networks (PANW).
As concerns grow, Japan’s regulators, banks, and cybersecurity agencies have begun creating countermeasures. Chief Cabinet Secretary Minoru Kihara stated the government will “move quickly” to address possible misuse.
The Financial Services Agency (FSA) in Japan has also set up a public-private framework to reinforce security measures. Meanwhile, the government plans to hold talks across relevant ministries and work with the ruling Liberal Democratic Party to agree on the next steps.
What Are the Best AI Stocks to Buy?
As of May 12, Anthropic remains a private company, with no publicly traded stock. However, investors seeking AI exposure can track publicly traded names such as Nvidia (NVDA), Microsoft (MSFT), and Google (GOOGL) in the TipRanks Stock Comparison Center. All three AI stocks carry Strong Buy ratings from Wall Street analysts, with MSFT having the highest projected upside of 37.16%.
