Niconico (Japanese: ニコニコ, Hepburn: Nikoniko), known before 2012 as Nico Nico Douga (Japanese: ニコニコ動画, Hepburn: Niko Niko Dōga), is a Japanese video sharing service based in Tokyo, Japan. "Niconico" or "nikoniko" is the Japanese ideophone for smiling.[2] As of 2021, Niconico is the 34th most-visited website in Japan, according to Alexa Internet.[3]

The site won the Japanese Good Design Award in 2007,[4] and an Honorary Mention of the Digital Communities category at Prix Ars Electronica 2008.[5]


Nobuo Kawakami, the founder and CEO of Niconico[6]

The first version of Niconico used YouTube as a video source. When the site grew, YouTube's server infrastructure strained due to increased traffic and bandwidth, leading YouTube to make a decision to block access from Niconico. As a result, Niconico ceased operations for two weeks. The site relaunched with an on-premises video server. On May 7, 2007, Niconico announced a mobile phone version of the website. Since August 9, 2007, "Nico Nico Douga (RC) Mobile" has serviced mobile phones of NTT DoCoMo and au.[7]

As of October 31, 2011, Niconico has over 23,690,000 registered users, 6,870,000 mobile users and 1,390,000 premium users.[8] Due to the limited server capacity, Niwango limits the number of free users who can access the website at peak times (7 p.m. to 2 a.m.), based on the time of registration. The website is in Japanese, and the majority of the site traffic is from Japan, although approximately four percent is from outside Japan, notably one percent from Taiwan.[9] Niconico launched a Taiwanese version of the site on October 18, 2007.[10] In July 2008, Niconico launched German and Spanish-language versions of the site,[11] followed by an update for the Taiwanese-language version. An English-language version was added on October 17, 2012, superseding the website, with translation functionality allowing users to translate video descriptions into English or Chinese.[12]

On April 27, 2012, Nico Nico Douga announced it would be rebranding itself as Niconico. The site also introduced a new "Zero" update, which improves video resolution, along with various other upgrades.[13]

Hiroyuki Nishimura served as director at Niwango until February 2013.[14]

Niconico launched for the Nintendo Switch in Japan on July 13, 2017, and was the Switch's first third-party media app in any market.[15]

Support for the English and Chinese-language versions of Niconico were discontinued on July 5, 2023, with the company citing the advancements in automated translation as a reason to deprecate the translations of the user interface, with comment fields, video titles and video descriptions the only natively supported translation on the site.[16]

2024 Ransomware attack

Main article: 2024 cyberattack on Kadokawa and Niconico

On June 8, 2024, a group of hackers called BlackSuit launched a ransomware attack on multiple Kadokawa-owned websites including Niconico, resulting in the website being taken offline. A feature-limited version of the website using select backup data was released on June 14.[1] On June 27, the hacker group published a statement on the dark web claiming responsibility for the attack and threatening to publish 1.5 terabytes of stolen data on business contracts and users unless a ransom was paid.[17][18]

In 2010, an English version was in the works.[19] Furthermore, in April 2011, an English-language beta website (Niconico) was launched. Unlike the Japanese counterpart of Niconico (, hosted videos from YouTube, DailyMotion, and Niconico. Similar to the pre-2007 version of Niconico, users can view the hosted videos via a version of the Niconico player, complete with commenting and tagging systems.[20] later introduced video upload and (for Premium users) live streaming functionalities. The site also simulcast select animetitles from June 2011. On October 14, 2011, Niconico announced a partnership with Funimation Entertainment to form Funico, to handle licensing of anime properties for streaming and home video.[21] With the implementation of English language features into, was retired on November 19, 2012, and now redirects to the Japanese website.[12][22]

In March 2018, Niconico announced the end of English-language community services.[23]

In October and November 2018, DDoS attacks from outside Japan led to disconnected services for some areas outside the country to combat these attacks.[24]

In September 2019, the antenna shop "Niconico Douga Headquarters" was closed and its functions were consolidated into the new studio "Haresta" in Ikebukuro.


Users can upload, view, and share video clips. Unlike other video-sharing sites, however, comments are overlaid directly onto the video, and synced to specific playback times. This feature allows comments to respond directly to events occurring in the video, in sync with the viewer—creating a sense of a shared watching experience. Niconico's atmosphere and cultural context are close to 2channel's or Futaba Channel's. Many popular videos on this site have otaku tastes, such as anime, computer games, and pop music. Niconico offers a feature for users (not just the uploader of the video) to tag videos. Each video may have up to eleven tags, of which up to five the uploader may lock. Frequently, this functionality can be used not only as categorization, but also as critical commentary, satire, or other humor related to the video's content. Certain tags may have an explanation attached to them in the form of a Niconicopedia (ニコニコ大百科, Nikoniko daihyakka) article, some being proper descriptions while others having a more comedic tone. The site is also known for its MAD videos and its medleys of popular songs on the website, most notably Kumikyoku Nico Nico Douga. Niconico also distributed some original net animations, such as Candy Boy, Tentai Senshi Sunred, and Penguin Musume Heart.[25]

Other features include:
