The verdict in three sentences
For a funded B2B software company in Tokyo, Google is still where Japanese buyers build their shortlist, usually in Japanese, before downloading a product deck (資料請求) that they circulate internally for approval. Serious SEO work generally shows first signals in 3 to 6 months and steady enquiries between months 7 and 12, for a market budget of roughly USD 2,000 to 5,300 a month with a Tokyo agency (2026 ballpark). The gap between vendors comes from Japanese pages written for the buyer, accurate security and compliance pages, and a document request path that feeds the sales team.
What your buyers in Tokyo actually type
Your buyers are IT leads (情報システム部), finance leads and operations leads. They search by category, by comparison and by compliance constraint, rarely by brand name at first.
| Query (example) | Intent type | Page that should answer |
|---|---|---|
| 経費精算 システム 比較 | Category comparison | Japanese category page with honest selection criteria |
| 電子帳簿保存法 対応 SaaS | Regulatory constraint | Compliance page describing actual support |
| SOC2 取得 SaaS 国内 | Security requirement | Security page listing only certifications held |
| [your category] 料金 | Pricing | Pricing page, or a range and pricing logic |
| [your category] 導入事例 製造業 | Industry proof | Real case studies, published with client consent |
| Salesforce 連携 [your category] | Integration | Integration page with the exact connector scope |
| B2B SaaS Tokyo English support | Foreign buyer in Tokyo | English page on support and billing |
| [your category] 資料ダウンロード | Ready to evaluate | Deck download page with a short form |
Two local notes. Software review and comparison platforms such as ITreview or BOXIL weigh on the journey; your site has to be consistent with what is published there. As for the downloadable deck, it travels through the internal approval process (稟議), so it must answer the questions the finance director will ask without you in the room.
Realistic timeline and Tokyo market budgets
| Period | What happens | Reasonable signs of progress |
|---|---|---|
| Months 1 to 3 | Technical audit, Japanese and English structure, product and security pages rewritten | Pages indexed, impressions rising on category queries |
| Months 4 to 6 | Comparison pages, integrations, client cases, first in-depth content | First clicks on non-brand queries, first deck requests |
| Months 7 to 12 | Consolidation, earned editorial links, updates to key pages | Steady deck requests, measurable share of pipeline from search |
No serious provider promises a ranking; these ranges depend on how competitive your category is and on the age of your domain.
| Option in Tokyo | Budget (2026 ballpark) | Note |
|---|---|---|
| SEO freelancer | JPY 100,000 to 300,000 a month, roughly USD 670 to 2,000 | Good for execution, rarely for strategy |
| Generalist SEO agency | JPY 300,000 to 800,000 a month, roughly USD 2,000 to 5,300 | Check B2B experience |
| Specialist SaaS and B2B content agency | JPY 800,000 to 1,500,000 a month, roughly USD 5,300 to 10,000 | Often includes content production |
| One-off audit | JPY 500,000 to 1,500,000, roughly USD 3,300 to 10,000 | Useful before a funding round or a redesign |
| In-depth Japanese article | JPY 30,000 to 100,000 per article, roughly USD 200 to 670 | Review by a product expert is essential |
| English translation and adaptation | JPY 15 to 25 per character, roughly USD 0.10 to 0.17 | Market assumption, depends on volume |

Content constraints and common mistakes
A funded vendor's content carries its credibility with buyers and investors alike. A few rules apply:
- Security and compliance: SOC 2, ISO 27001 (ISMS) or ISMAP are shown only if genuinely obtained, with their scope. GDPR is mentioned only if you actually process data of EU residents.
- Personal data: demo and deck forms fall under Japan's Act on the Protection of Personal Information (APPI), supervised by the Personal Information Protection Commission (PPC). Transfers of form data to a tool hosted outside Japan deserve particular care.
- Comparative claims: unsupported “No. 1” claims, common in Japanese marketing, have drawn regulator attention; publish only verifiable statements. This is not legal advice.
- Clients and numbers: logos, cases and metrics only with the client's written consent.
The mistakes we see most often: an English site machine-translated into Japanese with no domain vocabulary; no pricing page or pricing logic; a 12-field form to download a deck; vague security pages that send the IT lead to a better documented competitor; a general-interest blog that draws traffic with no buyers in it.

Mini case study
Illustrative example: “Kumo Ledger KK”, a fictional Tokyo vendor of expense management software that has raised a Series A. It plans a USD 6,000 audit and a retainer of USD 4,000 a month, so 6,000 + 4,000 × 12 = USD 54,000 in year one. Its average annual contract value is JPY 2,700,000, roughly USD 18,000. It therefore needs 54,000 ÷ 18,000 = 3 contracts signed from organic search to cover year one, before renewals. If the site produces 30 deck requests a month from month 9 and 3% become contracts, that is about 0.9 contracts a month, so the target is reached in roughly 4 months.
FAQ
How long before the first clients arrive from Google?
Expect 4 to 6 months for first enquiries and 7 to 12 months for a steady flow, depending on how competitive your category is. No serious provider promises a specific ranking.
Do we need a site in Japanese and English?
For Japanese buyers, Japanese is essential: most category queries are typed in Japanese. English serves foreign subsidiaries in Tokyo and investors, often across 10 to 20 key pages.
What monthly budget should we plan in Tokyo?
Roughly USD 2,000 to 5,300 a month with a generalist agency and USD 5,300 to 10,000 with a specialist B2B agency (2026 ballpark, converted from yen). At Kolonell, SEO work is on quote.
Should we display our security certifications?
Yes, only those genuinely obtained, with their scope and date. A precise security page is often one of the 5 most visited pages by an IT lead.
Do review platforms replace SEO?
No, they complement it: buyers often check 2 or 3 sources before downloading a deck. Your site has to confirm what they read elsewhere.
