Japanese SEO Agency
A Japanese SEO agency runs search work for the Japanese market in Japanese: keyword research, content, technical work and local link building. The deciding question is who writes the content.
Three of the ten ranking slots are not agencies. Clutch, GoodFirms and YouTube hold them, which shortens the real shortlist to seven.
The weakest ranking agency, at DR 0.2, outranks a firm at DR 58. Authority is not deciding the agency slots.
Translation is not localisation. Keyword research has to happen in Japanese first, or the page targets a term nobody types.
Expect slower outreach. Our own reply rate into Asia Pacific domains is about half our .com rate.
We measured every ranking domain in August 2026, then checked our own outreach records for how country domains actually respond.
Asia Pacific country domains replied 3.31% of the time across 453 contacts we emailed and tracked, against 6.50% for .com across 7,481. Roughly half.
They are also scarce in our records: 757 of 22,636 contacts sit on an Asia Pacific country domain, against 15,024 on .com.
Three .jp domains rank on the term, at DR 8, DR 24 and DR 29, alongside .com domains at DR 39, DR 40 and DR 58.
The two directories are the strongest results by far, at DR 91 and DR 86. Those slots are not winnable, and they are also not competitors.
Searching for a Japanese SEO agency returns a page that is doing two different things at once, and if you read it as a ranking of agencies you will draw the wrong conclusion. We measure agency results pages this way across verticals, from golf to architecture.
Three of the ten slots are not agencies
We pulled the Ahrefs Domain Rating for every ranking result in August 2026. The two strongest results by a wide margin are Clutch at DR 91 and GoodFirms at DR 86, both agency directories rather than agencies. YouTube at DR 99 takes a third slot.
Directory slots behave the same way in every agency market we have measured, including SEO outreach agencies. That matters in two ways. First, your real shortlist from page one is seven firms, not ten. Second, if you are an agency trying to rank here, three of the slots are structurally unavailable and no amount of content changes that.
Among the seven actual firms the spread is wide and the order is surprising. The weakest sits at DR 0.2, close to a brand new domain, and it ranks above a firm at DR 58. Three Japanese country domains rank, at DR 8, DR 24 and DR 29, alongside firms on .com domains at DR 39 and DR 40.
The median for the whole page is DR 40, but that number is carried by the directories. Strip them out and the agency slots are contestable. Five of the ten domains sit under DR 40. For comparison, across thirty-three vertical marketing and SEO terms we measured in the same week, the median of the per-page medians was DR 58.
Translation is not localisation
This is the single most expensive mistake in the category, and it is worth being blunt about.
Translating an English page preserves the meaning of your English keyword choices. Those choices were made against how English speakers search. Run them through translation and you get grammatically correct Japanese aimed at a phrase nobody types. The page reads fine to a human and is invisible to search.
Keyword research has to be done in Japanese first, and content written to that research. Not translated afterwards. Any agency that describes its process as translating your existing content is selling you a language service and calling it search.
Ask who writes the content and in what order. A good answer is that a native speaker researches terms, then writes originals. A weaker answer is that content is written in English, translated, then reviewed. The second can work for supporting pages but it will not win competitive terms.
Outreach into Japan is measurably slower
If link building is part of the plan, this is the number to budget against, and we have it from our own sends rather than from a study.
We tag every contact by the country domain of its email address and track whether it ever replied. Contacts on Asia Pacific country domains, which includes .jp, replied 3.31% of the time across 453 tracked contacts. Contacts on .com replied 6.50% across 7,481. That is close to half.
They are also thin on the ground in our records: 757 of 22,636 contacts sit on an Asia Pacific country domain, against 15,024 on .com. The pattern is consistent across the other groups too, with .uk at 5.53% and European country domains at 3.89%, so this is about reaching outside the .com world generally rather than about Japan specifically.
The practical consequence: a Japanese campaign needs a longer prospect list and a longer timeline to produce the same number of placements. If an agency quotes you the same monthly link volume it quotes for an English campaign, ask how, because the reply rates do not support it. Our guide to monthly link building services covers what a realistic monthly number looks like.
It also raises the value of getting the pitch right rather than sending more of them. Our link building checklist covers the parts that move reply rates.
Local firm or international one
Page one does not settle this, because both are on it and neither type dominates. The honest split is by what you need.
A firm in Japan is usually better for language quality, for relationships with Japanese publishers, and for catching the cultural detail that makes copy land. The three country domains ranking here are all of this type.
An international firm is usually better if Japan is one of several markets, if you need one reporting line across all of them, and if your team works in English. Firms on .com domains hold several of the slots here.
The question that separates good from bad in either case is the same one: who writes the Japanese, and are they writing or translating. Everything else is preference. If you are weighing keeping the work in house against handing it over, our guide to outsourcing link building covers the same trade-off on the outreach side.
What the work actually covers
Keyword research in Japanese. Done natively, including the different scripts a term can be written in, which is a genuine technical complication that has no English equivalent.
Content written rather than translated. Covered above, and the thing to police hardest.
Technical work for a multi-language site. Language targeting, correct URL structure, and making sure the Japanese pages are not treated as duplicates of the English ones.
Local link building and press. Japanese publications, industry titles and regional media, which is where the reply rate above becomes your planning constraint. Expect quotes in yen and in local formats; our roundup of what backlinks cost shows how widely publisher pricing varies once you leave the English-language market.
If you are running several markets rather than only Japan, our note on relevant backlinks covers why a link from a Japanese publication is worth more for Japanese rankings than a stronger link from an English one.
Questions to ask a Japanese SEO agency
Who writes the Japanese, and do they write or translate? The single deciding question.
Was the keyword research done in Japanese or translated from an English list? Ask to see the list.
What monthly link volume do you expect, and how does it compare with your English campaigns? If the numbers match, ask why.
Which Japanese publications have you actually placed in? URLs, not a count. Our reporting guide covers what a verifiable placement report looks like.
Who handles technical language targeting? Especially if your site already serves several languages.
When to hire, and when not to
Hire when Japan is a real revenue target rather than an experiment, because the ramp is slower than an English market and a short trial will not show results.
Hire local if content quality is the priority. The ranking evidence shows small Japanese firms compete perfectly well.
Do not hire anyone proposing to translate your existing pages and call it market entry.
Do not benchmark the campaign against your English one. Different reply rates, different timelines, different competitive set.
Doing the outreach part yourself
MentionAgent is $99/mo flat. It is not an SEO agency and does not replace one. It handles one piece: finding articles already covering your topic, verifying the right contact, writing a pitch tied to that specific piece, and sending it once you approve it in Telegram.
It works in the language of the article it finds, and every draft comes to you for approval before it sends, so you keep editorial control over anything going out in a language your team may not read. No credits, no per-contact fees, no per-placement billing and no minimum term.
Get mentioned in the publications your market actually reads
MentionAgent finds the outlets covering your topic, verifies the contact and drafts the pitch. You approve every send. $99/mo flat, whatever the volume.
Start Getting Mentioned On AutopilotFrequently asked questions
How do I choose a Japanese SEO agency?
Start by ignoring the top of the results page, because three of the ten slots are Clutch, GoodFirms and YouTube rather than agencies. The genuine firms sit below them. Then ask one deciding question: is the work written in Japanese by a native speaker, or is it English content translated afterwards.
Is it hard to rank for Japanese SEO agency?
The median Domain Rating on the page is 40, but that is inflated by two directories and YouTube. Among the actual agencies the spread runs from DR 0.2 to DR 58, and the weakest ranking agency at DR 0.2 outranks a firm at DR 58. Five of the ten domains sit under DR 40.
Should I hire an agency in Japan or an international one?
Both are on page one, so the results do not settle it. A local firm is usually better for language quality and publisher relationships. An international firm is usually better if Japan is one of several markets and you need one reporting line. The test is who writes the content, not where the invoice comes from.
Is outreach into Japan harder than into English markets?
Measurably. In our own outreach, Asia Pacific country domains including .jp replied 3.31% of the time across 453 tracked contacts, against 6.50% for .com across 7,481. That is roughly half. Budget for a longer list and a slower ramp, and question any agency quoting the same volumes as an English campaign.
Can I just translate my existing English pages?
Not if you want them to rank. Translation preserves the meaning of your English keyword choices, and those were made against English search behaviour. The words people type are different and a translated page tends to target a term nobody searches. Research the keywords in Japanese first, then write to that.
