If your company is entering Japan and you want organic search to be part of your acquisition strategy, you have probably already discovered that Japanese SEO is not simply a matter of translating your existing content. The market has its own search patterns, content conventions, and trust signals — and ignoring them is one of the most common reasons foreign brands fail to gain traction in Japan's search results.
This article covers the key differences you need to understand and the practical steps to address them.
Why Japanese Search Behaviour Is Different
Japan is a Google-dominant market — roughly 70–75% of searches happen on Google, with Yahoo! Japan (which now uses Google's search engine) accounting for much of the rest. So in terms of pure ranking factors, you are optimising for Google just as you would elsewhere. The difference lies in how people search.
Japanese users tend to type shorter queries, often using a mix of kanji, hiragana, and katakana. The same concept can be expressed in multiple scripts, and searchers may use any of them. For example, a foreign company selling project management software needs to consider queries written in kanji (プロジェクト管理), katakana loanwords (タスク管理), and even romaji abbreviations used in B2B contexts.
Mobile search is dominant, but desktop still accounts for a significant share in B2B — a pattern that affects how you format content and what page speed benchmarks you should target.
Building a Japanese Keyword Strategy
Keyword research in Japan requires native-level understanding, not just a translation tool. A few things to watch for:
Loanwords vs. native Japanese terms: Many concepts have both a katakana loanword (e.g. マーケティング, "marketing") and a native Japanese equivalent. Both may be searched, and they sometimes attract different audiences. B2B tech queries skew heavily toward katakana; consumer searches are more mixed.
Long-tail is less saturated: Because Japanese content production in many niches is still lower than English, mid- and long-tail keywords are often achievable for new entrants without massive domain authority. This is one of the genuine advantages of moving early.
Intent signals in the query: Japanese searchers are generally more research-oriented before contacting a vendor. Queries like "〇〇 とは" (what is X), "〇〇 メリット" (benefits of X), and "〇〇 比較" (X comparison) are high-volume and indicate strong purchase intent further down the funnel.
On-Page SEO: What Changes for Japan
The technical fundamentals — crawlability, page speed, structured data — are identical to any other Google market. Where things differ:
Title tags and meta descriptions: Japanese characters are wider than Latin characters, so the effective character limit for a title tag is roughly 30–35 characters (vs. ~60 in English). Frontloading the target keyword matters even more in Japanese because search results truncate quickly.
Content length expectations: For informational queries, Japanese search results are dominated by long-form articles — 2,000 to 4,000 characters is common for competitive topics. Short-form content tends to underperform in organic rankings. This means your localisation budget needs to account for original, expanded content — not just translated copy.
Internal linking: Japanese SEO practitioners place high importance on internal link structure, and Google Japan's quality assessments appear to reward it. Flat, well-linked site architectures tend to outperform siloed ones.
Content and Trust: Where Most Foreign Sites Fall Short
Japanese web users have a well-documented preference for information density and thoroughness. A site that looks sparse by Western design standards may be perceived as low-trust or lacking authority in Japan.
Specifically:
- Company information pages matter: A detailed 会社概要 (company profile) page with address, capital, founding date, and representative name is expected. Its absence is a trust red flag, particularly in B2B.
- Author credibility: For content in YMYL-adjacent topics (health, finance, legal, business advice), demonstrating expertise through named authors, credentials, or affiliated organisations improves both user trust and how Google evaluates the content.
- No invented statistics: Japanese readers are sceptical of vague claims. Cite specific, verifiable sources or omit the numbers entirely.
Local SEO and Google Business Profile
If you have any physical presence in Japan — an office, a showroom, a partner location — claim and optimise your Google Business Profile in Japanese. NAP (name, address, phone) consistency across Japanese directories such as Tabelog, Yelp Japan, and industry-specific listings also matters.
Even for companies with no physical presence, structured data (Organization schema) with a Japanese-language description helps Google associate your domain with Japan-market queries.
Working With a Japanese Agency
For most foreign companies, the most practical path to Japanese SEO is partnering with a bilingual agency that understands both your home market and how Japan's digital landscape operates. The key questions to ask:
- Do they do original Japanese copywriting or rely on machine translation with light editing?
- Can they handle technical SEO audits in Japanese CMS environments (WordPress, Shopify, Next.js)?
- Do they understand the regulatory context for your industry in Japan?
- Can they report in your language while executing in Japanese?

Conclusion
Japanese SEO is achievable for foreign companies, but it requires treating Japan as a distinct market rather than an afterthought to your global site. The key priorities are:
- Build a genuine Japanese keyword strategy — not a translation of your English one
- Produce long-form, authoritative content that meets Japanese readers' expectations
- Make your company information transparent and trust-building
- Invest in technical fundamentals and internal linking
The companies that succeed in Japanese organic search are the ones that commit to understanding the market rather than applying a global template and hoping for the best.
