Why is Demon Slayer loved in Japan? Have you heard of a manga called “Demon Slayer” or “Kimetsu no yaiba” in Japanese? It is an action adventure manga about “Demon” which kills people and “Kisatsu-tai” which fight against them. The manga artist, Koyoharu Gotoge is an up-and-coming who made a debut with it in 2016. This manga has been coming up a lot in Japan. According to the comic ranking in 2019, its circulation is over 12 million copies and ranked the 1st exceeding “One peace” which circulation is 10 million copies. “One peace” is one of the most popular manga around the world and it won the 1st in the ranking for over 10 years until “Demon Slayer” beat it. The sales increased rapidly since it started to broadcast anime on TV in April 2019. The number of issues was about 4 million before the broadcasting in May but it was over 12 million just before the end of anime in September 2019. One of the main reasons for this hit is to be turned into anime. It is known that to broadcast anime helps to raise the sales of the manga which was seen about “Attack of Titan”. “Demon Slayer” was not succeeded at first because a lot of the main characters died in the story and the picture was supported by not everyone. TV anime changed this impression by making the story simpler and making the picture very vibrant and lively. In the fall in 2020, the movie will begin in Japan.
