Technical SEOTechnical SEO Japan: crawl budget, Core Web Vitals, indexation and structured data fixed for Japanese sites — audited properly, priced in JPY.
Technical SEO Japan starts underneath the content: how fast pages load for Japanese users, whether search engines can crawl and index them, and whether the right version reaches the right searcher. In Japan the bar is unforgiving — mobile-first buyers bounce fast, and technical debt compounds quietly until rankings fall off a cliff.
We run technical SEO for Japanese clients remotely from our Manchester studio, measuring speed from Japan test locations on local networks rather than from a UK server that flatters the numbers. Crawl analysis uses your own log files to show what bots actually do on your site, and every fix is verified in the rendered output before it counts as done.
Large Japanese sites bring large technical problems: faceted catalogues burning crawl budget, JavaScript frameworks that crawlers only half-render, consent banners that accidentally hide content, and legacy URL structures nobody dares touch. That is exactly the work this service exists to do — methodically, with evidence, and without breaking what already ranks.
Engagements begin with a Japanese-market audit: technical health, Japanese keyword landscape, presence on Yahoo! Japan and LINE, and whether the site meets Specified Commercial Transactions display requirements. Monthly cycles: technical fixes, Japanese-native content written for how Japan searches (not translated English), LINE Official Account strategy where relevant, and outreach to Japanese media. Reporting is detailed and precise — Japanese clients expect thoroughness, and we match it.
LCP, INP and CLS diagnosed and fixed, measured from Japan locations on real Japanese connection profiles — not lab scores from another continent.
Faceted navigation, parameters and thin URLs tamed so crawlers spend their budget on pages that earn money, not on filter combinations.
Canonicals, robots rules and sitemaps rebuilt so the right pages index, duplicates consolidate, and junk stays out of the results.
Rendering audits for React, Next.js, Vue and headless builds — what the crawler sees versus what your visitors see, and where they diverge.
Server logs reveal real crawl behaviour: wasted budget, orphaned money pages, crawl traps and error loops invisible in standard tools.
Schema built and validated for products, services, FAQs and local entities, so Japanese pages earn rich results instead of markup errors.
Language and regional versions wired correctly so Japanese searchers land on the right version and versions stop cannibalising each other.
Redirect maps, pre-launch checks and post-launch monitoring for redesigns, domain moves and platform changes — rankings protected end to end.
Full crawl, log review, speed testing from Japan, rendering and hreflang checks.
Findings ranked by ranking impact against dev effort — tickets, not essays.
We fix what we can directly and spec the rest sprint-ready for your developers.
Every fix re-tested from Japan: field data, crawl behaviour, rendered output.
Crawl stats, indexation and Core Web Vitals tracked as changes roll out.
Documentation your team keeps, so fixes survive the next redesign.
Technical decay is silent. A Japanese site rarely loses rankings in one dramatic drop; it bleeds — a template change here, a plugin update there, a redirect chain that grows by one hop every quarter. By the time traffic visibly falls, the causes are layered months deep. Our audits reconstruct that history from crawl data and logs, then fix causes rather than symptoms.
The Japanese market context shapes how technical seo has to work here. Japan is the world's third-largest ecommerce market with its own rules. Buyers research exhaustively on smartphones — train-commute browsing shapes everything — and expect dense, detailed pages: specifications, comparisons, FAQs and reviews all above the fold by Western standards. Search is overwhelmingly in Japanese (mixed kanji/kana scripts); English queries are a thin expatriate and B2B slice. Yahoo! Japan still matters for older demographics, and LINE Official Accounts plus LINE Ads reach audiences Google can't.
Consent and compliance are technical SEO issues in Japan. Cookie and consent tooling that loads late, blocks rendering or gates content can hide pages from crawlers and wreck Core Web Vitals. We test the consented, unconsented and crawler views of your site separately, then fix the conflicts without weakening your compliance position.
We also see the same avoidable mistakes across Japan. The recurring failures: translated-English sites with thin information density (Japanese buyers bounce from 'empty' pages); ignoring LINE entirely; checkout without konbini payment options; and Western-minimalist design that signals low effort to Japanese eyes. Also: machine-translated keigo that gets politeness levels wrong — a trust-killer. Build Japanese-first, not English-adapted.
The local specifics are not decoration — they change decisions. Google leads (~75-80%) but Yahoo! Japan retains real share as a portal. LINE is the dominant platform (~95M users) — LINE Official Accounts are essential for business messaging. Ecommerce: Rakuten Ichiba, Amazon.co.jp, Mercari (C2C). X (Twitter) is unusually strong in Japan; Instagram and TikTok growing. Note: Facebook is weak here. Cash still significant; konbini (convenience store) payments are a uniquely Japanese ecommerce method. Credit cards growing; PayPay dominates QR mobile payments; Suica/Pasmo transit IC cards double as e-money. Bank transfer (furikomi) for B2B.
Nowhere is that clearer than in Tokyo. Tokyo concentrates Japan's finance, media, tech and corporate headquarters: Marunouchi bankers, Shibuya/Shinjuku retail gravity, Akihabara electronics culture, and the world's largest concentration of Fortune Global 500 HQs. Search competition is national-grade in every category — ranking here means beating the best-funded agencies in Japan.
Working in Japan also means working the Japanese way. Consensus decision-making (ringi), long-term relationships over quick wins, meticulous quality standards, extreme punctuality. Seasonal campaigns are ritualised (New Year fukubukuro, Golden Week, Obon, year-end oseibo). Japanese web aesthetic favours dense, information-rich pages — minimalism can read as 'empty'. Politeness registers (keigo) in copy signal respect.
Toyama City tells the same story at a different scale. Pharma B2B is world-class and specialised. Alpine tourism is seasonal. The compact-city policy concentrates commerce — local search is centre-focused. Competition is moderate.
Regional reality matters in Japan too. Hokkaido: Sapporo: tourism, winter sports, agriculture and dairy — strongly seasonal demand patterns. Shikoku: Four prefectures of manufacturing, agriculture and pilgrimage tourism; smaller, relationship-driven markets. Kanto: Greater Tokyo — the world's largest metro economy: finance, tech, media, corporate HQs and the densest consumer market in Japan. Our technical seo programmes are planned around these regional economies, not a single capital-city template.
Coverage runs the whole country, not just the capital: Technical SEO in Tokyo, Technical SEO in Osaka, Technical SEO in Nagoya, Technical SEO in Fukuoka, Technical SEO in Sapporo and Technical SEO in Kobe. Every engagement is run from our Manchester studio with Japanese market specialists, and every city page above carries the local detail for its market — start from the Japan hub for the full picture of what we deliver in Japan.
A technical audit and fix programme typically runs ¥320,000–¥960,000 for an audit and fix programme, depending on site size and complexity. Large catalogues and JavaScript-heavy builds sit at the higher end. You get a fixed quote before any work starts.
No. We work inside your sprints: tickets sized to your velocity, fixes verified in staging, nothing merged without your team’s review. Most clients find technical SEO speeds releases up, because fewer emergencies interrupt the roadmap.
Both. Configuration-level fixes — robots, canonicals, sitemaps, redirects, schema — we implement directly. Code-level work is specced precisely for your developers and verified by us after release, so nothing is signed off on trust.
Crawl and indexation improvements usually appear within two to six weeks of implementation. Core Web Vitals gains show in field data after 28 days of measurement. We report against baselines set in the audit, so progress is provable rather than promised.
Yes. Findings arrive as sprint-ready tickets with acceptance criteria, and we join standups or async threads during the overlap window. We verify every fix in staging before it ships, and again in production after release.
Yes — speed and rendering tests run from Japan locations on local network profiles, because a test run from London measures a journey your Japanese customers never take. Field data from your real users is weighted above every lab score.
Crawl budget is how much of your site search engines bother to crawl. Sites with huge filtered catalogues, infinite parameters or millions of thin URLs waste it on junk while money pages go stale. Log file analysis in the audit shows exactly where your crawl goes.
Yes — strategy and reporting can run in English while all customer-facing work is native Japanese, written for Japanese search behaviour and politeness conventions, not translated from English.
