"Do we need a Japanese website?" is one of the first questions foreign companies ask when entering the Japanese market. It sounds simple, but the answer matters more than most people realize — and getting it wrong can quietly cost you deals, visibility, and credibility.
Here is a practical breakdown to help you decide.
The Short Answer: Almost Always Yes
Japan has one of the highest internet penetration rates in the world, but Japanese consumers and buyers behave very differently online than their Western counterparts. A few key facts shape this:
Language is a trust signal. Japanese buyers — B2C and B2B alike — are far less likely to purchase from, or even seriously consider, a company whose website is English-only. Even if your main point of contact speaks English fluently, their procurement committee, finance team, or decision-makers above them may not. A Japanese website signals that you take the market seriously.
Google Japan rewards Japanese content. Search behavior in Japan skews heavily toward Japanese-language queries. A well-optimized Japanese site ranks for searches where your English-only site simply will not appear. If you want inbound leads from Japan, you need Japanese content indexed by Google Japan.
LINE is the dominant communication channel. LINE is used by over 95 million people in Japan, and businesses use LINE Official Accounts to communicate with customers, send promotions, and provide support. A Japanese website gives you a credible home base to direct LINE followers toward — without one, your LINE presence has nowhere to land.
When a Minimal Approach Makes Sense First
There are a few situations where you might reasonably delay a full Japanese site:
Early-stage market validation. If you are still testing whether there is genuine demand in Japan, a single well-translated landing page with a contact form may be enough to qualify inbound interest before committing to a full build. This is not a permanent strategy, but it is a reasonable starting point.
Enterprise B2B through a local partner. If you are entering Japan via a distributor or joint venture and all customer-facing activity will be handled by your local partner, a Japanese page on your existing global site may suffice for the first phase. Check with your partner — they will know what their customers expect to see.
These are exceptions. For most companies entering Japan independently, a proper Japanese-language site is not optional.
What Makes a Japanese Website Different
A Japanese website is not just a translation of your English site. Several things need to change:
Information density and design expectations
Japanese web design tends to be more information-dense than Western minimalist styles. Menus often carry more items, pages include more text, and visitors expect to find detailed information without clicking through several layers. A very sparse, minimalist design can come across as unfinished or lacking substance. Modern Japanese sites are moving toward cleaner layouts, but completely stripping out content rarely works.
Honorific language (keigo)
Japanese has a formal register system that extends well beyond polite speech. B2B copy in particular must use appropriate business keigo. Machine translation will not consistently handle this — you need a native Japanese writer or editor to review anything customer-facing. Poor language register signals that you do not understand the market, which erodes trust before a conversation starts.
Local trust signals
Japanese buyers look for specific signals your home market may not require. These include:
- A company overview page (会社概要) with registration details
- A physical address in Japan (or a clear explanation if you do not have one yet)
- A named contact person
- A privacy policy written for Japan's personal information protection law (APPI / 個人情報保護法)
Missing any of these will raise questions — especially in B2B contexts where procurement teams conduct due diligence.
How to Build a Japanese Website: Three Paths
1. Hire a bilingual agency based in Japan. This is the most reliable approach. An agency that works in both Japanese and English can handle translation quality, local UX expectations, technical SEO for Japan, and cultural nuance — all under one roof. If you are working with someone in the Kyushu or Fukuoka region, a bilingual web agency can also advise on local market specifics. This is the path that tends to produce the best long-term results.
2. Use your existing agency plus a professional Japanese translator. This works if your current agency is technically solid and you have a trusted native Japanese translator (not just a machine translation service). The risk is coordination gaps — the translator may not have context on web copy conventions, and the developer may not catch cultural missteps. Plan for extra review rounds.
3. Build in-house. Only practical if you already have Japanese-speaking marketing staff and an internal web team capable of ongoing content updates. Do not underestimate the maintenance requirement — a static site that never updates is a negative trust signal in Japan's SEO landscape.
Budget Expectations
For a foreign company building a Japanese-language marketing site (not e-commerce), rough guidance:
- Simple landing page or single-page site with a contact form: around ¥200,000–¥500,000
- Small brochure site, 5–10 pages, Japanese copywriting included: around ¥500,000–¥1,500,000
- Full marketing site with blog, case studies, and SEO optimization: ¥1,500,000 and up
The biggest variable is who writes the Japanese copy. Original Japanese copywriting costs more than translating from English, but it almost always performs better in search rankings and in conversion — because a skilled Japanese copywriter writes for the actual audience, not a translated version of your English audience.
What to Do Next
If you are in early research mode, the most useful first step is a conversation with someone who has done this before. A free consultation can help you figure out what you actually need versus what can wait.
When you are ready to scope a project, come prepared with:
- A clear description of your target customer in Japan (industry, company size, role of the buyer)
- The action you want site visitors to take (contact form, demo request, LINE follow, download)
- Any hard deadlines (trade shows, product launches, distributor agreements)
A Japanese website is an investment, not just a line item — but only when it is built with the right audience and the right goals in mind. Start with clarity on those two things, and everything else becomes much easier to scope.
