LINE is the most popular social media platform in Japan followed by Twitter, Instagram, Facebook, and TikTok. When comparing the Monthly Active Users (MAU) of these 5 social media platforms, LINE is obviously the most dominant in the Japanese market in 2019.

LINE’s penetration rate is surprisingly high. Actually, it is higher than the smartphone penetration rate in Japan. This is because there are also many non-smartphone users who access LINE from a computer or tablet device. LINE has 80 million MAU compared to the nation’s 70 million smartphone users.
