Japanese authorities have launched an investigation into Grok, the artificial intelligence service developed by Elon Musk, after concerns emerged about the generation of inappropriate images. The probe began on 16 January 2026, according to officials familiar with the matter.

The investigation follows reports that Grok produced images that may violate Japanese standards on harmful or explicit digital content. Therefore, regulators are examining whether the service complies with local laws governing online platforms and AI-generated material.

🔍 Role of Japanese Regulators

Japan’s Consumer Affairs Agency confirmed it is reviewing the issue. Officials said they are gathering information from the service provider and assessing how the images were generated and distributed.

Meanwhile, regulators said they will evaluate whether existing safeguards were sufficient. They also plan to determine if the service breached guidelines designed to protect users from harmful content. Consequently, the probe will focus on compliance rather than enforcement at this stage.

🤖 Concerns Over AI-Generated Images

Authorities said the investigation centres on how Grok handles image generation prompts. They want to understand whether the system includes effective filters to prevent inappropriate outputs.

However, officials clarified that the probe does not yet indicate wrongdoing. Instead, they described it as a fact-finding process. Therefore, regulators will first seek clarity on how the system operates and how developers respond to content risks.

🌐 Wider Scrutiny of AI Platforms

Japan has increased oversight of AI services as their use expands across industries. Meanwhile, lawmakers continue to debate how existing laws apply to generative AI tools that can create text and images on demand.

Officials said they are particularly concerned about platforms that can generate visual content quickly. Consequently, regulators aim to ensure that AI developers take responsibility for preventing harmful outputs.

🏢 Response From xAI

xAI, the company behind Grok, has not issued a public response specific to the Japanese probe. However, the firm has previously said it works to improve safety measures and content moderation across its AI services.

Meanwhile, regulators said they expect cooperation from the company during the review. They added that the process will involve technical explanations and documentation related to image-generation controls.

📌 Next Steps in the Review

Japanese authorities said the probe will continue in the coming weeks. They will decide whether further action is needed once they complete their assessment.

For now, officials emphasised that the review aims to ensure compliance and user safety. Consequently, the outcome will depend on the findings related to safeguards, system design, and response mechanisms.
