The Japanese media is much like ours, they have the freedom to say or do whatever they want. But depending on where it is showcased there may be restrictions, but that's the same as here. The biggest difference that I found is the music listened to by teenagers. In America, most teens prefer rap which has lots of swearing, but in Japan, they listen to jrock, is more of an electric genre of rock.
Like here in America Japan has access to all information, with no government restrictions. If you think your privacy has been violated you have the right to file a complaint and a investigation will take place. I noticed in most shows and movies instead of swearing they instead say words like "punk" and "brat." The biggest social media app in Japan is Line, which is an app where you can text, facetime, and video message your frineds.
Japan has differences in the shows that they watch. For example one of the most popular shows in Japan is called " Sekai no Hate Made Itte Q" which means "Go to the end of the World." In this show, Japanese Celebrities and comedians, travel to different parts of the earth and participate in events, and festivals. But there are also some similarities in shows. Like "Love is blind: Japan" which is the exact same as our Love is blind just in Japan. Where people looking for marriage go on dates and by the end get engaged without ever seeing each other's face.
