The Ultimate Guide to using LINE Japan for advertising your business

Post Series: LINE

Do you have a business you would like to promote in Japan? If your goal is to effectively reach the Japanese audience, then advertising on LINE Japan may be the best solution for you. There are several ways foreign companies can use the LINE platform to leverage their marketing campaigns in Japan. Here is the ultimate guide for non-Japanese companies wishing to advertise on LINE Japan.

What is LINE Japan?

LINE is Japan’s most popular social media platform. Similar to WhatsApp and WeChat, LINE is a messaging app that allows users to chat and make free calls to friends. Most famous for its animated stickers, this super app also has other services such as LINE News, LINE Shopping, LINE Manga, LINE Games, and more. Learn more about LINE Japan.

Engage with fans and customers via your LINE Official Account

A LINE Official Account allows you to have a business profile page in LINE, where you can: update ‘friends’ on promotions, make posts in Timeline, increase online engagement with customers, send direct messages for customer support and share coupons for special deals. You can find further details on LINE Official Account or in the latest LINE Business Guide.

Reach Japanese mobile users with LINE Ads

With 86 million MAU, which amounts to approximately 68% of the entire Japanese population, LINE Ads is the most effective way to reach Japanese mobile users. Similar to CPC ads on other popular social media platforms, your LINE Ad will appear in different locations within the LINE app as well as the LINE Ads Network, which includes an array of other apps. You can pay per click on banner ads or by impression for highly effective video ads. You can also define your target audience according to user demographics and interest as well as lookalike audiences. Find out more on how businesses can use LINE Ads in Japan

How LINE compares to Facebook in Japan

While LINE JAPAN has 86 million MAU in Japan, Facebook only has 26 million. Yet, because of Facebook’s global popularity, many businesses run Japanese advertising campaigns on Facebook without researching which social media channels their target audience is using. You can find out more on why LINE Ads might be a better digital strategy for your Japanese campaigns over Facebook Ads.
