LINE

LINE is the dominant messaging app in Japan, Taiwan and Thailand, where its position resembles WhatsApp's in Europe — most people use it as their default way to reach anyone.

It goes well beyond chat: payments, news, a sticker economy, and Official Accounts that businesses use for customer service and promotions. In Japan a LINE Official Account is a standard part of a company's customer contact stack.

For cross-border sellers targeting these markets, LINE is usually where support conversations happen, and its broadcast messaging typically achieves far higher open rates than email.
