Google’s New AI Search Controls: What Global Teams Should Decide for Japan

Google has turned participation in its generative AI search features into an explicit business decision.

On August 31, 2026, Google completed the worldwide rollout of a new Search Console control that allows website owners to include or exclude their sites from generative AI features. The control covers AI Overviews, AI Mode and generative AI features in Google Discover.

At first glance, this may look like another technical setting for an SEO team to manage. It is more consequential than that.

For a multinational company, changing the setting can affect how localized content is discovered in individual markets. A policy chosen at global headquarters may flow down to regional sites, including a Japanese subdirectory or subdomain. The decision therefore belongs not only to SEO, but also to legal, content, product marketing and local market teams.

The important question is no longer simply, “Can our website appear in AI search?”

It is now, “Do we want it to appear—and who should make that decision for each market?”

What Has Changed in Google Search Console?

Google’s Search generative AI control provides three options.

1. Include the site

This is the default setting. The site’s links and content can appear in supported generative AI features and may help ground AI-generated responses. The site can receive impressions and traffic from these features.

Inclusion makes a site eligible. It does not guarantee that Google will show, cite or link to any particular page.

2. Exclude the site

If a site is excluded, its links and content will not appear in the covered generative AI features or be used to ground their responses. The site will not receive impressions or traffic from those features.

Google states that this choice is not used as a ranking or inclusion signal in other parts of Search. In other words, opting out of the supported AI features does not, by itself, remove a site from conventional Google results.

The setting also has a narrower purpose than some site owners may assume. It does not control AI model training; Google directs site owners to Google-Extended for that purpose. It is also different from noindex, which prevents content from appearing in Google Search more broadly.

3. Inherit the choice from a parent property

This is particularly important for international websites.

A Search Console property can inherit the AI-search setting of its closest configured parent. For example, a Japanese URL-prefix property may inherit a decision made for the top-level domain. However, an owner of the child property can manually override the inherited setting for that property and its subpages.

This means information architecture and Search Console ownership now affect AI-search governance. Before changing anything, global teams should understand which domain, subdomain and URL-prefix properties exist, who owns them and how the setting will cascade.

Google Also Added Dedicated AI-Search Reporting

The control arrived alongside dedicated generative AI performance reports in Search Console.

The Search report provides impression data for AI Overviews and AI Mode. Website owners can review:

• Pages appearing in the supported generative AI features
• Countries where those impressions originated
• Devices used for the searches
• Changes over time

Google provides a separate report for generative AI features in Discover.

These reports make the decision more informed, but they do not provide a complete AI-search measurement system. An impression indicates that a link to the site was shown. It does not, by itself, demonstrate brand preference, lead quality or commercial impact.

For a Japan-focused analysis, the new reporting should be combined with conventional Search Console data, analytics, branded-search trends, conversion data and controlled observation of commercially relevant prompts. SEO remains the foundation; AI-search reporting adds another view of discovery.

Why Japan Should Be Evaluated Separately

An international company may operate one global domain, but its localized pages do not all perform the same job.

The English site may already have extensive category pages, technical documentation, case studies and brand recognition. The Japanese site may still be establishing basic market understanding. Its most valuable pages might explain unfamiliar terminology, local product availability, implementation requirements, customer support or the differences between a global offering and the version available in Japan.

This changes the potential trade-off.

If headquarters opts out because of concerns related to publishing rights, content licensing or global risk, that decision may be reasonable for some content. But applying it automatically to the Japanese site could remove an additional discovery route for localized product pages and educational content.

The opposite assumption is equally risky. Inclusion should not be treated as the automatic answer for every organization. A publisher with licensed material, a platform hosting third-party content or a company operating in a regulated category may have valid reasons to limit participation.

The point is not that Japan must always opt in. It is that Japan should not inherit a global choice without a local impact assessment.

A Practical Decision Framework for Global and Japan Teams

Before changing the setting, I recommend working through the following six steps.

Step 1: Map the Search Console property hierarchy

List the relevant domain and URL-prefix properties for the global and Japanese sites. Identify which property is the parent, which properties inherit its setting and which local owners have permission to make changes.

For sites using structures such as example.com/jp/, jp.example.com or a separate Japanese domain, the governance path may differ. Do not assume that the organization’s reporting structure and its Search Console structure are the same.

Step 2: Define the role of Japanese content

Group important Japanese pages by business purpose rather than reviewing them as one undifferentiated website.

Useful groups may include:

• Product and service pages
• Technical explanations and documentation
• Comparison and use-case content
• Research, insights and educational articles
• Support, policy and legal pages
• Licensed or third-party material

Then ask which groups support initial discovery, which build confidence and which create legal or licensing concerns.

Step 3: Establish a baseline

Use the new generative AI performance reports to identify which Japanese URLs already receive impressions and from which countries. Export the data and record the review period before changing the control.

If the report is not visible, do not immediately conclude that the site has no AI-search presence. Google notes that a property may not show the report when it has not received enough impressions. The absence of a report is therefore not the same as evidence of zero business value.

Step 4: Review rights and risk

Legal and content owners should determine whether the site includes licensed material, sensitive information, third-party submissions or content subject to specific regulatory requirements.

This review should distinguish between appearing in generative AI search features, model training and appearing in Google Search generally. Those outcomes are controlled differently, and treating them as one issue can lead to the wrong implementation.

Step 5: Agree on ownership and record the decision

Assign a named owner for the final setting. Document:

• The selected option
• The Search Console property affected
• The reason for the decision
• The stakeholders who approved it
• The implementation date
• The date of the next review

This is especially important where a global owner controls the parent property but a Japan team manages local performance.

Step 6: Monitor business outcomes, not only impressions

After implementation, monitor page-level and country-level AI impressions alongside organic traffic, branded demand and meaningful conversions such as qualified enquiries, demo requests or downloads.

Avoid treating one favorable AI response—or one visibility score—as proof of success. AI Overviews and AI Mode can use different models and techniques, so the responses and links they show may vary. The objective is to understand patterns across strategically important topics, not to promise a citation for a fixed prompt.

AI-Search Governance Does Not Replace SEO

Google’s own documentation remains clear: the same foundational SEO practices continue to apply to AI Overviews and AI Mode. A page must be indexed and eligible to appear in Google Search with a snippet before it can be eligible as a supporting link. Google does not require a separate technical markup or a special “GEO page type.”

That makes conventional SEO work just as important:

• Ensure important Japanese pages can be crawled and indexed
• Match content to real Japanese search intent rather than translating an English keyword list
• Provide clear, original and locally accurate information
• Use internal links to establish relationships between products, topics and supporting evidence
• Maintain strong page experience and technically sound templates
• Make important claims easy for both users and systems to understand and verify

AIO, AEO and GEO can help teams think about how content is retrieved, interpreted and represented in answer-based experiences. They are complementary disciplines, not substitutes for solid SEO and localization.

My Recommended Starting Point

For a commercial website actively trying to build awareness and demand in Japan, and with no significant rights or regulatory constraints, retaining the default inclusion setting is a reasonable starting point. It preserves eligibility for AI-search discovery while the team gathers real performance data.

That is not a universal recommendation. Sites with material licensing, publisher or compliance concerns may reach a different conclusion. The decision should follow evidence and a documented risk assessment—not convenience, fear of change or an unreviewed setting inherited from headquarters.

The broader lesson is simple: AI-search visibility is becoming part of market governance.

Global consistency still matters. But consistency should not mean ignoring the commercial role, content maturity and risk profile of the Japanese site.

Before your company changes the switch, bring SEO, legal, content and the Japan team into the same conversation.
