How to Add Japanese to Your Website (Without a Developer)

Japan is the world’s fourth-largest e-commerce market and the third-largest economy. Japanese consumers spend heavily online, prefer to buy in their own language, and are fiercely loyal to brands that speak to them properly. If you’re looking to expand into Japan, adding Japanese to your website is the single highest-impact step you can take.

The good news: you don’t need a developer, a translation agency, or months of work. This guide shows you how to add Japanese to any website — regardless of platform — in a few minutes.

Why Japanese specifically?

Japanese is one of the most commercially valuable languages to add to a website, for several reasons.

High purchasing power. Japanese consumers have one of the highest average online spending rates in the world. A Japanese visitor who can read your site is significantly more likely to convert than one who can’t.

Low competition in translated content. Many international businesses translate into Spanish, French, and German first. Far fewer translate into Japanese. This means less competition for Japanese search queries — your translated pages can rank faster and higher.

Search engine behavior. Japanese users search in Japanese, almost exclusively. They’re not searching in English and hoping for results. If your site doesn’t exist in Japanese, it doesn’t exist in Japan.

Brand loyalty. Japanese customers who find a brand that communicates well in their language tend to become repeat buyers. The initial investment in translation pays returns for years.

The challenge with Japanese

Japanese is one of the harder languages to translate well, for reasons that don’t apply to European languages:

Three writing systems. Japanese uses kanji (漢字), hiragana (ひらがな), and katakana (カタカナ) — often in the same sentence. The correct mix depends on context, formality, and convention.

Formality levels. Japanese has distinct politeness registers. Product descriptions, customer service text, and legal pages each require different levels of formality. A translation that uses the wrong register sounds jarring or unprofessional to Japanese readers.

Word order. Japanese sentence structure (Subject-Object-Verb) is the opposite of English (Subject-Verb-Object). Simple word-for-word substitution produces unreadable results.

No spaces between words. Japanese text doesn’t use spaces. Line breaks and text wrapping need to happen at grammatically appropriate points, which affects your page layout.

These challenges are why basic machine translation (Google Translate, for example) often produces awkward or incorrect Japanese. Context-aware AI translation handles these nuances significantly better.

How to add Japanese to your website in 3 steps

Go to **proxylang.dev **and create a free account. Add your website’s domain. No credit card required.

Step 2: Add the script tag (a few minutes)

The setup wizard asks which platform your site runs on, then shows you exactly where to add your one-line script snippet for that platform:

WordPress: Skip the snippet entirely — install the free Proxylang plugin from wordpress.org. No code editing needed.
Shopify: Paste the snippet into your theme’s theme.liquid file, just before </head>.
Squarespace or Wix: Paste it into the Custom Code / Header injection panel in your site settings.
Cafe24 or IMWEB: The wizard walks you through the equivalent steps in each platform’s own admin panel.
Any other site: Paste the snippet into your <head> tag — the wizard helps you find it if you’re not sure where that is.

If your site connects through your domain’s DNS rather than a page builder, Proxylang also detects your domain registrar automatically and gives you the exact records to add.

Step 3: Select Japanese and configure (5 minutes)

Use the Setup Wizard to quickly add your website:

Select Japanese (日本語) as a target language
Add your brand name so it stays in its original form (or specify a katakana version if you prefer — e.g., “NordSkin” → “ノルドスキン”)
Save and visit your site

Click the language switcher. Your site is now in Japanese.

What the AI handles automatically

Proxylang’s LLM-grade translation handles the specific challenges of Japanese:

Writing system mixing. The AI knows when to use kanji, hiragana, and katakana based on modern Japanese convention. Foreign brand names get katakana. Common words get their standard kanji/hiragana forms.

Appropriate formality. Product descriptions use polite-form Japanese (です/ます体). The AI maintains consistent register across your site.

Natural word order. Sentences are restructured to follow Japanese grammar, not word-for-word translated from English.

Line-wrap and layout adaptation. Since Japanese text has no spaces between words, Proxylang breaks lines at grammatically appropriate points so text wrapping doesn’t break your page layout.

Japanese SEO: getting found on Google.co.jp

Translating your site is step one. Getting it found by Japanese searchers is step two.

Starting on the Start plan ($39/mo), Proxylang’s Hybrid mode gives your Japanese pages:

Separate URLs: yoursite.com/ja/ for every page
Japanese hreflang tags: telling Google this is the Japanese version of each page
Translated meta titles and descriptions: so your Google.co.jp search results show in Japanese
Pre-rendered HTML for search engine crawlers: bots see fully translated, indexable content, even though regular visitors still get the lightweight script-tag translation

Upgrading to the Pro plan ($99/mo) unlocks Full Proxy mode, which serves those same translated URLs to every visitor, not just search engine bots — the closest thing to running a fully separate Japanese site, without maintaining one.

Getting listed on Naver or Daum — relevant if you also have Korean customers — still requires a few manual steps inside each search engine’s own webmaster tools. Proxylang’s dashboard walks you through exactly what to submit and where.

Japanese keyword behavior

Japanese searchers use different query patterns than English searchers. For example:

English: “best project management tool”
Japanese: “プロジェクト管理ツールおすすめ” (project management tool recommendations)

Proxylang translates your meta tags and content in a way that aligns with how Japanese users actually search, not just literal translations of your English keywords.

Image translation for the Japanese market

If your website includes images with text — product banners, infographics, size charts, promotional graphics — Proxylang automatically detects the text inside those images and generates Japanese versions with matching fonts and layout. There’s no manual tagging step required; the AI finds text-bearing images across your site on its own.

This is particularly important for:

E-commerce: Size charts, ingredient lists, promotional banners
SaaS: Feature comparison graphics, onboarding screenshots
Restaurants and hotels: Menu images, facility guides

Common mistakes when adding Japanese

Don’t use Google Translate and copy-paste. The output is often grammatically incorrect or uses inappropriate formality. Japanese readers notice immediately, and it damages trust.

Don’t translate your brand name unless you want to. Decide upfront whether your brand name stays in English or gets a katakana transliteration. Add it to your Translation Glossary either way so it’s consistent across all pages.

Don’t forget mobile. Most Japanese internet use is mobile. Check that your translated site and language switcher work properly on mobile devices.

Don’t ignore the checkout flow. If your checkout, shipping options, and return policy aren’t in Japanese, customers will abandon the cart even if your product pages are perfectly translated.
