Technical SEO decides whether your Japanese pages can be found, crawled, indexed and understood at all. On an international website it is also where the most expensive mistakes live, because one misconfigured rule can quietly remove an entire language version from search results.

The failure mode we see most often

The Japanese pages exist and look fine in a browser, but they are not indexed — or they are indexed and pointing their ranking signals somewhere else. A canonical tag inherited from the English template, an hreflang cluster that is not reciprocal, a parameter-based language switch, or JavaScript rendering that hides the Japanese content from the crawler. Each is invisible in the browser and decisive in search.

Why the Japan case needs its own attention

A Japan-facing site section rarely stands alone: it sits inside a global website with a shared template, a shared CMS and a shared set of rules that were designed for the primary market. Getting Japan right means checking how those global rules land on the Japanese URLs specifically, rather than assuming a site-wide audit already covered it.

What we do

Crawl, indexation and rendering audit

We check what search engines can actually reach and render on your Japanese URLs, including JavaScript-dependent content and blocked resources.

International configuration review

Hreflang reciprocity, canonicalisation, URL architecture and language-switching behaviour are checked as a system, not as isolated tags.

Core Web Vitals and performance

We identify what is actually degrading LCP, CLS and INP for Japanese users on Japanese pages, and prioritise the fixes with real impact.

Structured data and site architecture

Schema, internal linking and information architecture are aligned so that the relationships between your Japanese pages are explicit.

What you receive

  • A prioritised technical audit, separating what is urgent from what is cosmetic
  • Specific findings for the Japanese URLs, not a generic site-wide report
  • Implementation guidance written for developers, with the reasoning included
  • Hreflang and canonical specification for your Japanese pages
  • Re-testing after implementation to confirm the fix actually landed

Who this is for

  • Global websites with a Japanese language version or subdirectory
  • Companies whose Japanese pages are not being indexed
  • Teams planning a site migration that includes Japanese pages
  • Businesses with Core Web Vitals problems on their Japan-facing site

Frequently asked questions

Either. Some clients want a specification their development team executes; others want us to work directly in the CMS or alongside their developers. We scope the engagement to match how your team is set up.

Not automatically, but it raises the stakes. We test what the crawler receives rather than what the browser shows, and recommend a rendering approach that makes your Japanese content reliably available to search engines.

Before the URL structure is finalised. Redirect mapping, hreflang and canonical planning are far cheaper to design in advance than to reconstruct after a launch has cost you visibility in Japan.
