This new line of additional features is revealed at the 2017 Line Conference in Tokyo, Japan, on Thursday (07/15/2017). These new features are in line with one of Line's three visions for the next five years, videolized (all things related to video or photos).
Senior Manager of Line Planning, Ayumi Inagaki explains, although the Line application has grown with various additional services, their cores remain communications. Therefore, a series of new features that Line released remain rooted in these values.
