One of the my favorite youtuber, Yuuki, is famous for his life in Japan.He basically introduces various culture of Japan for korean who want to know about it.The different point from another youtuber is his mood of video.He always take a video all by himself. And, it makes people who watch it feel being with him. Most of The comments of his video are “the way you taking video is really feel comfortable”. Subscribers who follow him feel like traveling with him. Also, Yuuki chooses interesting themes for video. These are quite unique things that many of foreign people want to know Such as “Visiting love hotel on Christmas by himself”, “Eating nagashi-somen in traditional way”. He really know people’s demand. I thought famous Youtubers always create stimulus contents for increasing subscribers, but Yuuki is different. He dose not use violent and sexual content. This is why most of his subscribers are woman. I hope this kind of Youtuber increases in future who dose not use any violent and sexual content.
