Maximise BigCommerce's SEO foundations and turn your Japanese catalogue into an organic revenue engine

BigCommerce is a less common platform choice in Japan than Shopify or domestic alternatives like BASE and STORES. Merchants who have chosen BigCommerce in Japan typically did so for specific reasons: stronger multi-storefront capability, better URL structure for international SEO, or B2B features. The relative scarcity of BigCommerce in Japan means there are fewer local agencies with genuine platform expertise — and it also means that well-executed BigCommerce SEO in Japan faces less direct competition in most product verticals.

BigCommerce supports Japanese-language storefronts via its multi-storefront feature: separate URLs, Japanese metadata fields, and Japanese product content can all be configured independently from an English storefront. The critical SEO requirement is correct hreflang implementation — Google needs to know which storefront is intended for Japanese searchers (ja) and which is intended for English speakers (en-JP or en). We configure both storefronts correctly and verify indexation for Japanese content in Google Search Console.

BigCommerce includes basic structured data, but JPY-denominated price markup, Japanese product names, and review aggregates from Japanese review platforms are commonly missing or misconfigured. We audit both storefronts against Google's requirements for Japanese rich results and implement the missing attributes. Japanese review platform compatibility (Rakuten reviews, local review tools) is assessed as part of the schema implementation.

The Japanese-language storefront needs hreflang lang="ja", the English-language storefront needs lang="en" or lang="en-JP" depending on the intended audience, and an x-default tag handles traffic from markets outside these two audiences. All three tag types need to be present on every page in both storefronts — not just the homepage. Hreflang must also appear in XML sitemaps. The most common errors we fix in Japan are missing x-default, incorrect language codes, and hreflang present only on the homepage.

Japanese keyword research requires different tools (Google Keyword Planner in Japanese, Yahoo Japan data where applicable), different intent mapping methodology (Japanese buyers search in different patterns from English speakers for the same product categories), and awareness of Japanese search modifiers. Direct translation of English commercial keywords into Japanese frequently produces search terms that Japanese buyers do not actually use. We conduct Japanese keyword research natively and validate search volumes against Japanese data sources.

BigCommerce SEO engagements for Japan-based merchants typically start from JPY 250,000–400,000 per month depending on catalogue size, whether the store is headless, and whether both Japanese and English content production is required. A bilingual engagement requires native Japanese content writing, which is a significant component of the investment. A search diagnostic is the right starting point and costs nothing.

Both platforms can support Japanese-language storefronts. BigCommerce's advantage is its multi-storefront feature — genuinely separate storefronts with distinct URLs for Japanese and English — which is cleaner for hreflang and canonical management than Shopify's language-toggle approach. For Japanese SEO specifically, the technical setup differences matter less than the content strategy: whichever platform you use, native Japanese category content is the primary driver of organic rankings in Google Japan.

Technical fixes show indexation improvements within four to six weeks. Japanese-language category content rankings take three to six months in competitive verticals. Japanese search competition in BigCommerce product categories is generally lower than English-language competition in the US or UK, which often means faster ranking progress for merchants who start producing native Japanese content. We assess the competitive landscape at the diagnostic stage and provide category-specific timelines.
