New research has shown that Line is currently the top social app in Japan. The Japanese software firm Just Systems has revealed that the app is by far the leading social platform amongst all age groups, particularly with people in their forties, 84% of whom use Line more than any other service. The only age group where less than 70% of respondents said they used Line the most frequently were those aged from 15 to 19, where less than 58% of those questioned said they used it most. The survey compared Line to other major social media apps such as Twitter, Facebook and Instagram. Additionally, another survey from Mobile Marketing Data Lab showed that around 90% of all smartphone users in Japan said Line was their preferred social media app.
