Google announced on July 16 that its personal AI agent Gemini Spark is now available in Japanese. The agent operates continuously on Google Cloud virtual machines, allowing it to process tasks in the background even when a user's smartphone or PC is turned off. Gemini Spark integrates with Google Workspace, Google Photos, YouTube, and search services. It can handle complex multi-step requests, such as checking replies to attendance confirmation emails and updating a spreadsheet automatically. Users can save frequently used workflows as skills. The agent asks for confirmation before executing important actions. Gemini Spark is available to Google AI Ultra subscribers in Japan. The plans are Google AI Ultra 5x at 14,500 yen per month and Google AI Ultra 20x at 32,000 yen per month. The service uses Gemini 3.5 Flash and the Antigravity harness. It is accessible via the Gemini app by switching from Chat to Spark Beta.
Google Japan announced the rollout in a tweet that described Gemini Spark as a "long-awaited personal AI agent" that runs 24/7 on behalf of the user. The agent supports the Model Context Protocol (MCP), a common standard for connecting AI with external services, allowing direct integration with compatible third-party apps beyond Google's own services.
Gemini Spark can be set to compile data that will be obtained in the future, not just existing data, enabling users to schedule tasks that trigger when new information arrives. The agent learns the content and procedures instructed by the user via prompts, and can efficiently reuse similar tasks as saved skills.
The rollout followed an initial testing phase and a US launch. Japanese users on the Google AI Ultra plan can access it by switching from Chat to Spark Beta in the Gemini app. Google emphasized that the agent asks for confirmation before executing important actions and does not indiscriminately read emails when integrated with Gmail.
