Boost Your Business with LINE: Unlocking Japan’s No.1 Messaging Platform

In a world where digital interaction is the key to success, companies need to leverage tools that enable frictionless customer interaction. At Charlesworth, we understand the strength of LINE Official Accounts in building genuine relationships and fueling business growth.

Why LINE is Important in Japan

LINE is not only a messaging app in Japan but a reigning digital platform. It has more than 92 million monthly active users in Japan and is the most used communication platform, beating other social media networks. In contrast to Western economies where there are several messaging apps utilized interchangeably, LINE in Japan is an all-inclusive platform with messaging, news, payments, shopping, and entertainment.

As a central tool in Japanese digital marketing, LINE offers unique opportunities for brands to connect with consumers. LINE Corporation’s survey revealed that more than 85% of Japanese smartphone users access LINE on a daily basis, making it a necessary application for companies to interact with customers. In addition, 65% of the users are fans of at least one business or brand on LINE, proving it might in online marketing and customer relations management.

Through strategic utilization of LINE Official Accounts, businesses can raise brand awareness, boost revenue, and create seamless engagement with their audience.

Four successful case studies are discussed in this article, which shows how various businesses have leveraged the potential of LINE Official Accounts.

LINE’s analytics features provide businesses with the ability to monitor message open rates, user engagement, and customer preferences.

Advertising and Promoting Your Business on LINE

One of LINE for business’s strongest capabilities is also its capacity for advertising and promotion. Businesses can utilize LINE Ads, sponsored stickers, and influencer deals to boost brand recognition and convert consumers.

LINE Ads

LINE Ads enable companies to build highly focused marketing campaigns by demographics, interests, and user behaviors. With in-depth audience segmentation, companies can target potential customers with exactly customized messaging and offers. These ads can be shown across LINE services, such as the LINE Timeline, LINE News, and LINE Manga, for extensive visibility.

Sponsored Stickers

LINE stickers in Japan are a cultural phenomenon, with users often downloading and applying them to daily conversations. Companies can design branded stickers that users can download for free if they follow the company’s LINE Official Account. This has been an effective way of increasing engagement and expanding customer databases.

Influencer and LINE VOOM Marketing

LINE VOOM is a short-video content feature on LINE, enabling brands to partner with content creators and influencers to showcase products in a fresh and authentic manner. Influencer marketing on LINE is utilized by numerous businesses as a means of building credibility and reaching new customer bases.
