Building for the Japan market
Japanese users expect dense, information-rich pages and flawless Japanese typography — not a translated Western layout.
Practically, that shapes how we build: checkout flows use the gateways your customers already trust (Stripe, PayPay, Komoju, Rakuten Pay), prices and dates render in Japan formats, and the SEO plan targets Japan search results rather than a generic global audience. Where you serve specific cities — Tokyo, Osaka, Nagoya, Yokohama — we build a page for each one with content written for that market.
