Apps & Business Systems
LINE, internal systems, and Japanese business convention — the parts of a Japan build that overseas teams routinely miss.
THE PROBLEM
Software that works everywhere else can still fall flat in Japan. The market runs on channels and conventions that are invisible from outside it, and they are not optional extras — they are how business is done here.
LINE is not optional in Japan. LINE is the messaging app most of Japan uses every day. For consumer-facing business here, a LINE Official Account is closer to a phone number than a marketing channel. Reaching Japanese customers without it means reaching a fraction of them.
Your development team is unlikely to have built for it. LINE's platform, LIFF apps, and the Japanese payment and identity services around them are documented primarily in Japanese. Overseas teams rarely have this on hand within a project timeline.
Japanese operations run on their own tools. Internal systems in Japan touch conventions foreign systems get wrong — name ordering, address formats, the corporate seal, fiscal-year boundaries, and invoice formats required under the qualified invoice system.
