LINE Messenger App

Japan’s most popular messaging app, LINE, has over 94 million MAU in the country and a total of 187 million globally3. Categorised as a super app and similar to the Chinese app WeChat, LINE has a multitude of features other than messaging, such as a newsfeed, a cashless payment system, a games library, TV streaming, digital comics and an ecommerce platform. What is more, famous for their animated stickers, LINE even has retail stores that sell official character merchandise.

As you can see in the graphs above, more than half of the LINE users are over 40, but this is mostly due to the aging population in Japan. Many people from every age group, for both men and women, use the app on a daily basis. This makes  LINE Ads one of the most effective ways for businesses to get ad impressions on smartphones.

The popularity of YouTube in Japan is undeniable. The video sharing platform had over 62 million MAU as of October 2018. According to Alexa, almost 5% of all traffic comes from Japan, ranking the country in 3rd place for number of visitors on YouTube4. According to the JustSystems “Mobile and Social Media Monthly Survey: December 2019 Edition” (see graph below) and Globalwebindex Q3 2019 survey1, YouTube is the most used social media platform in Japan among internet users.

A platform known to be dwindling in users and tweets worldwide is still experiencing massive popularity in Japan. In terms of users, Japan comes in second place after the USA with 48.45 million users1. Similar to LINE, the catalyst for Twitter’s popularity was the 2011 Tohoku earthquake and tsunami, where people needed an up-to-date source of information and means of communication. Twitter saw a 33% increase in Japanese users that year.

The secret behind Twitter’s popularity, however, may be attributed to the use of aliases on anonymous accounts. As Reuters mentions we also believe that this allows Japanese users to express their opinions freely, making Twitter a great platform to collect market data on products and services.
