Meta's Personal AI "Muse" Lands in Japan: A Next Competitive Axis That Pairs Well with iPhone Duo

Muse Arrives in Japan

Meta has started its personal AI service, Muse, in Japan. It first launched in the United States in September 2026 and later spread to Canada. The Japan launch came on October 23, 2026, around the same time Apple released its folding phone, the iPhone Duo. The columnist says the two work very well together.

What Is an Always-On AI Agent?

An always-on AI agent is an AI helper that keeps running in the background. It reads your emails, messages, calendar, and files. Then it does tasks for you, such as adding meetings to your calendar or finding news you care about. It runs in the company's cloud, so you can use it on your phone without setting up a special computer.

Key Facts

• Muse launched in the U.S. in September 2026.
• Muse launched in Japan on October 23, 2026.
• Before Japan, Muse was only in the U.S. and Canada.
• A device called Muse Charm is planned for release at the end of 2026.

Why It Matters

Muse shows where AI competition is heading. Instead of just answering questions, AI helpers now act on their own and warn you before things go wrong. Meta also chose Japan because it sees Japanese characters and anime as a strong fit for Muse. Meta is also planning small hardware devices and an open-source kit so others can build Muse-compatible gadgets.
