SEARCH GOVERNANCE / JAPAN WEBSITES
Google’s Search AI controls:
check the Japan site before a change.
A global AI policy needs a precise website scope. Start with the property that governs your Japan pages.
THE FIRST CHECK
Identify the Japan property and its inherited setting before changing a global control. Google’s Search generative AI control separates AI-search inclusion from training. A child property can inherit a parent’s choice or have an owner-set override. [1]
02 / NAME THE INTENDED OUTCOME
“Block AI” is not a complete instruction.
Ask the person requesting a change to finish the sentence: “We want to stop our content being used for ___.” Then record which product and which pages they mean. This is MEW’s proposed starting point for a conversation between a Japan marketing lead and a global site owner.
The Search control covers AI Overviews, AI Mode and generative features in Discover. Exclusion removes the site’s content and links from those experiences; it is not a ranking or inclusion signal for other parts of Search. Google describes the control as available to a subset of owners. [1]
Google-Extended serves a different purpose. It governs specified uses of crawled content for future Gemini model training and grounding in Gemini Apps and Vertex AI. It does not determine inclusion or ranking in Google Search, and it is a robots.txt token rather than a separate HTTP user agent. Do not treat it as a universal switch for every use of AI. [2]
For a B2B team, the useful output is a clear instruction that the site owner can evaluate: the business purpose, the relevant service and the exact content scope. A broad policy label leaves too much interpretation to whoever implements it.
03 / FOLLOW THE PROPERTY STRUCTURE
Find the boundary around your Japan pages.
A Search Console property is a defined asset, not a business department. A Domain property covers its subdomains and protocols. A URL-prefix property is narrower: protocol, host and path matter. A separate domain is outside the original domain’s scope. [3]
For inherited AI settings, follow the closest parent with a manually configured choice; otherwise inheritance reaches the top-level domain. A child owner can override that inheritance. [1] The illustration below turns those rules into three starting points for a Japan-site review.
One Japan business.
Three possible site structures.

example.com property
Review its own setting.
Arrows show nesting, not an observed setting. Intermediate properties and explicit overrides need checking.
MEW’s interpretation: start a review with URLs, not a label such as “Japan website.” Collect the product, pricing, trust and contact pages the local team depends on. Ask the site owner to map those URLs to the relevant properties. This creates a shared object to discuss before anyone decides whether a regional exception is appropriate.
Do not recommend a new domain or a site migration merely to simplify this map. The diagram is a way to inspect an existing setup, not a preferred international website architecture.
04 / MAKE THE REQUEST CHECKABLE
Give the site owner a small change record.
MEW recommends the following record before a decision. A solo operator can fill both roles; a larger company can use it to coordinate local marketing and the person authorised to change the setting. It is not a Google-required form.
| Record | What to keep |
|---|---|
| Purpose | The intended outcome, affected Google service and business reason. Resolve an ambiguous “AI opt-out” request first. |
| Japan URLs | The actual pages in scope, their property type and full property identifier. Include supporting pages on other hosts. |
| Current choice | A dated record of the visible setting, any inherited parent and any explicit override. Mark unavailable information as unknown. |
| Decision | What should change, what should remain, and who has authority to act. Do not assume that a Japan marketing role grants access. |
| Follow-through | The old value, actual change time, a review date and a restoration plan. Keep the record even if the decision is to make no change. |
If the control is unavailable, leave the status unresolved and consult the owner and current documentation. In the MEW property checked for this guide, the linked control page returned “page not found.” That observation does not establish why it was unavailable or what other accounts can access. No setting was changed.
After an authorised change, evaluate configuration and performance separately. Allow for propagation rather than treating an immediate search as a definitive test. [1] Save comparable reporting conditions; the MEW guide to Google’s AI report explains the counting limits.
Allowing inclusion does not guarantee that a page will appear. Google still requires an indexed page eligible for a search snippet, and says there is no special AI schema to add. [4] Once access is understood, examine whether the destination helps a buyer verify the product and take a useful next step.
05 / SOURCES & LIMITS
Documentation, not an outcome study.
Sources checked on 28 August 2026. This guide combines Google’s documented rules with MEW’s proposed review process. It does not test a settings change, measure lost traffic, or establish a preferred policy for every business.
No usable control screen was available in the checked MEW property. The original diagram therefore explains the structure; it does not reconstruct a product interface. Recheck availability and documentation before acting.
