The whole system down of Dwango Co,. Ltd. & Kadokawa group is a serious incidence especially in Japanese network. All the websites and the whole network server of Japanese video posting sites Nico Nico Douga (the potential competitor of YouTube) is completely down, and the recovery will take at least 1 month plus. This cyber incidence should be considered as a national cricis of Japan as Nobuhiro Tsuzi, the outsourced agent of the cyber security department of Japanese police, and Hiroyuki Nishimura, one of the initial founders, say. The vulnerability of Japanese server centre and the cyber security is questioned. Also, the shut-down of Nico Nico Douga causes the significant loss of the opportunity for the market competition and the entertainment creators. There are also various resources of BGM and pictures shared among many creators including YouTubers are stored in Nico Nico sites. Mr Tsuzi and Mr Nishimura, one of the initial founders, suspect it will take more and this cyber incidence is considerably serious.
