Muse AI in Japan: What Launched, What Is Still Coming

Meta’s personal AI agent has crossed its first ocean. Muse launched in Japan on 23 October 2026 — the first market outside North America, after the United States on 8 September and Canada on 18 September 2026. If you have been tracking where Muse is available, Japan is the third country on that list, and the first test of whether a personal agent built for North American apps can win over users whose daily services are different.

Quick answer: Muse launched in Japan on 23 October 2026, its first market outside North America. Gmail and travel links are live; Mercari and Ticket Pia are still to come.

The launch is worth reading carefully, because Meta’s own announcement draws three lines that most launch coverage blurs: what is live now, what is planned with named Japanese partners, and what was shown at Connect but is still waiting for a separate Japan announcement. Confusing those three is how a “coming soon” feature turns into a false launch claim. Here is the split, verified against Meta’s Japanese newsroom post of 23 October 2026.

What exactly launched in Japan on 23 October?

Muse became available in Japan on 23 October 2026 (Japan time) on iOS, Android and the web at muse.ai, with many basic features free and subscription plans for deeper use.

That is the whole launch in one sentence — and the important word is “basic”. Meta’s announcement says many basic features are free, with subscription plans available for users who want more, but it publishes no yen prices in the Japan post, and independent launch summaries note the same gap. Do not quote a Japan subscription price until Meta publishes one; the US tiers do not automatically carry over.

What Muse itself does is unchanged from the North American product: you tell it a task or a larger goal in chat, it builds a plan, and it carries the work forward — opening a browser, filling in forms, and continuing longer tasks after you close the app, notifying you when something changes or when it needs your approval to send an email or make a purchase. It also remembers what matters to you across conversations and uses that context for suggestions, a point Meta repeats in the Japan announcement.

What can Muse in Japan do today?

The live connectors are the global ones: Gmail, Google Calendar and Instagram, plus Stripe, Shopify, Trip.com, Agoda and Klook for shopping and travel.

In practice, that means the Japan launch is immediately useful for the jobs most readers already do in chat: summarising unread email, managing a calendar, drawing on saved Instagram content, and planning or booking shopping and travel through the global services above. Kyodo News, reporting the launch on 23 October, highlighted the same two starting points — Gmail for email summaries and Google Calendar for schedule management — and quoted Meta Japan head Masahiro Ajisawa saying Meta wants to connect Muse with services people use regularly so it can help in a wider range of situations.

One early travel detail is worth noting: launch coverage reports Klook’s tours and activities are already reachable inside Muse in Japan, so a traveller can ask the agent to help choose an experience and start a reservation, while payment still happens on Klook’s own checkout. That split — agent does the search and setup, merchant keeps the transaction — is the model to watch as more partners arrive.

What is still coming to Muse in Japan?

Three named Japanese services are planned, not live: Mercari, Money Forward ME and Ticket Pia.

Meta’s wording is “we will proceed with partnerships” with Mercari (the flea-market app), Money Forward ME (the household-finance and asset-management app) and Ticket Pia (ticketing). ITmedia’s same-day report draws the line explicitly: Gmail and the global services are already connected, while these three Japanese services are planned. Treat any claim that Mercari already works inside Muse as unconfirmed until Meta or Mercari announces it live.

Why those three matter more than a longer partner list: they cover the three places a personal agent earns daily trust — selling something you own, seeing where your money actually goes, and getting into an event. A resale listing needs accurate item details and a price you approve; a finance view needs read access you can revoke; a ticket purchase needs a payment step you explicitly confirm. If Muse gets those three right, the agent graduates from a chat helper to a daily utility. If it rushes them, it repeats the approval and privacy arguments that have followed Muse since launch.

What is NOT in Japan yet?

The advanced Connect features — an enhanced voice mode, the expressive Muse Realtime Avatar and a Muse email address — await a separate Japan announcement.

Meta’s Japan post says so plainly: the Connect announcements will be communicated separately for Japan. The Realtime Avatar is also English-only, which is a further reason not to assume it arrives in Japanese on day one. Our October early-access status update covers these features for the programme as a whole; for Japan specifically, the honest status is “announced at Connect, not confirmed for Japan”.

Feature or service	Status in Japan, 26 October 2026	What that means for you
Gmail, Google Calendar, Instagram	Live	Email summaries, schedule management, saved-content use
Stripe, Shopify, Trip.com, Agoda, Klook	Live	Shopping and travel planning and booking help
Mercari, Money Forward ME, Ticket Pia	Planned	Announced partnerships; do not expect them in-app yet
Enhanced voice mode, Realtime Avatar, Muse email address	Announced later	Connect features; separate Japan announcement pending
Japan subscription pricing in yen	Not published	Basic features free; do not quote a yen price yet

How does Meta say your data is protected?

Meta says Muse runs in an isolated Muse Secure VM per user, an independent Sentinel agent manages internet access, Muse cannot see your passwords or payment methods, and it asks before sending email or making a purchase.

Three controls matter most in practice. First, you choose which apps Muse can access and how much scope it gets, and you can change permissions or disconnect at any time. Second, you can review actions Muse has already taken and actions it still plans, so approval is not a one-time grant. Third, you can opt out of having your conversations used to train Meta’s AI models.

“Muse does not share your conversations or virtual-machine data with Meta’s advertising systems.” — Meta, Japan launch announcement, 23 October 2026 (translated from the Japanese newsroom post)

Read that sentence narrowly, as written: it is a rule about advertising systems, not a blanket promise that Muse will never carry advertising. Nikkei Asia reported on 24 October that Meta says Muse will stay ad-free and monetise the international push through non-ad means such as paid plans, but that reporting rests on a paywalled interview lead — so treat “ad-free” as reported, and the no-sharing-with-ad-systems line as Meta’s own stated rule. The distinction matters, and conflating the two is exactly the kind of overclaim this article avoids.

What does the Japan launch mean if you are not in Japan?

Japan is the template for the next launches — and the checklist below is what to watch before assuming your country is next.

For readers in India, the honest position has not changed: our India availability check found no launch date and no waitlist, and the Japan launch adds no India date. Japan matters for India readers only as a signal — Meta chose a market with strong local services and a subscription-friendly audience, and it launched there with global connectors first and local partners second. If that sequence repeats, the next launches will likely be announced the same way: global connectors on day one, named local partners as “proceeding”, and advanced features held for a separate announcement.

What to watch next, in order: (1) Mercari, Money Forward ME or Ticket Pia going live in-app — the first one to ship proves the local-partner pipeline works; (2) a yen subscription price — the first published price outside North America sets the pricing precedent; (3) a Japan date for the Realtime Avatar or enhanced voice mode — the first advanced feature to cross over; and (4) any fourth-country announcement, which would tell us whether Japan was a one-off or the start of a monthly cadence. Until one of those lands, Japan is a launch, not a rollout wave.

One caveat, stated plainly: this article is desk-researched from Meta’s Japan announcement and contemporaneous reporting, and was not hands-on tested in Japan — Muse is not available in India, where this site is written, and no Japan account was used. Connector statuses above reflect Meta’s 23 October announcement and launch-day reporting, verified on 26 October 2026, not a live in-app check.

Frequently Asked Questions

Is Muse available in India after the Japan launch?

No. As of 26 October 2026, Muse is confirmed in the United States, Canada and Japan only. Meta has announced no India launch date and no India waitlist, and the Japan launch does not change that.

Can I use Mercari through Muse in Japan today?

Not on the evidence available. Meta announced it will proceed with a Mercari partnership, but launch-day reporting is clear that this is a planned integration, not day-one availability. Check the app’s connector list before assuming it is live.

Do I need a subscription to use Muse in Japan?

No for basic use: Meta says many basic features are free, with subscription plans available for deeper use. No yen subscription price was published in the Japan launch announcement, so do not rely on a quoted yen figure until Meta publishes one.

Can Muse see my passwords or card details?

Meta says no: Muse cannot see your passwords or payment methods, it asks before sending email or making a purchase, and each user gets an isolated Secure VM for connected-service data and credentials. You can also disconnect apps and opt out of training use of your conversations.

Will Muse in Japan show ads?

Meta’s stated rule is that Muse does not share your conversations or virtual-machine data with its advertising systems. Nikkei Asia reported on 24 October that Meta says Muse will stay ad-free, but that report is paywalled beyond its lead, so treat “ad-free” as reported rather than as Meta’s published rule.
