Metagold: A Research Blog about Nico Nico Douga RSSフィード

So what is Nico Nico Douga? (For Non-Japanese readers only)

Non-Japanese readers might ask, what the whole fuzz is about. Most Western observers of the Internet still do not know that something like Nico Nico Douga even exists at all. So I thought it might make sense to give a very basic introduction of what Nico Nico Douga is (of course there is also wikipedia, but information in English is pretty basic).

Nico Nico Douga is a video-sharing platform – a genre that is in the West nowadays predominantly associated with YouTube. Nico Nico Douga was originally created as a mash up of Youtube and 2-channel – the latter is Japan’s most popular BBS (bulletin board system). Since last summer, Nico Nico Douga has its own servers, and therefore streams all video content on its own.


The interface of Nico Nico Douga – English translation

The most spectacular innovation of Nico Nico Douga is the way comments are placed on Nico Nico Douga. Users of Nico Nico Douga can write directly on the moving image. They comment while they watch videos, and add the comments directly on top of the video. All following users can see comments of former users as part of the video (most comments scroll into the frame of the moving image from right to left, and remains visible for some 4 seconds).

Users comment the videos that are streaming in the background, as well as each other’s comments. In the embedded video above you find a rather typical example for this. The amount of comments varies. Sometimes you find only one of two comments scrolling over the video. At other moments the whole screen is full (this is called a “Danmaku”). When the amount of comments on a video exceeds a certain limit, old comments make space for new comments.

To be able to see how this looks like, just click on any of the Nico videos on this blog, and you will see these comments scrolling through the videos. However, you do not see the interface where you yourself can put in such comment. To access this interface, you have to access Nico Nico Douga. It is free, but the interface is in Japanese. If you can handle this, give it a try. It is indeed a very interesting and new experience to write on videos with the click of one button!


A Youtube user gives a step-by-step introduction how to join Nico Nico Douga. Please note: This is not me speaking :). This video very useful, if you want to join, but otherwise, this guy misses most of the fun. He treats Nico Nico Douga as if it would be Youtube. Which it isn't.

From a technical perspective all this is no rocket science. What makes Nico Nico Douga so special is the way this platform has taken up. Nico Nico Douga exists since little more than one year, but is by now the 6th most visited website in Japan. There are by now more the 6 million registered users, more than one million (!) uploaded videos, and more then one billion (!!) comments – and all this in the course of not more than one and a half years.

Apart from the commenting function there are many other features that make Nico Nico Douga very interesting for our research. The second attribute of Nico Nico Douga is the amount and the nature of UGC (user generated content) that you can find on it. The majority of videos on Nico Nico Douga are not only uploaded, but also created by users (and indeed, it is now, with some exceptions, forbidden to upload TV content on Nico Nico Douga, due to the pretty strict copyright laws in Japan).

Popular genres include “MAD movies”, that are self-made music videos that remix exiting footage), often combined with songs that are performed by vocal synthesiser (the singing is created by a popular software called Vocaloid). You can find lots videos of gamers filming themselves, and there is also a fare amount of “Tried singing” and “Tried dancing” – these are categories on the platform, so no insult here to the amateur artists.


The famous Video Number 9 - the oldest video of Nico Nico Douga!

A lot of this content is the result of an almost evolutionary work of video making: Fans copy each other in thousands and thousands of versions (the vocaloid star “Hatsune Miku” is maybe the most known). Most videos are therefore part of a giant collaborative work process, and not so much single pieces of content. Again, there is much more to be said about this collaborative form of creation, and more about this on this blog soon.

Nico Nico Douga has by now a huge and devoted fan base of“Nico Chuus” (which you might translate as“Nico Nico junkies”). Nico Chuus watch huge amount of videos every day. Some of them produce videos, other only upload, and many comment only – some of them might even only watch, but they are still Nico Chuus, because of the huge role that Nico Nico Douga has in their lives.

Nico Nico Douga might remain a specifically East Asian phenomena - BBS are much more popular in East Asia then in the West. More recently, Niwango (the company behind Nico Nico Douga) has launched a Taiwanese version, but still most of the content and the comments remain Japanese. Nico Nico Douga suddenly catapulted Japan to the forefront of web innovation (originally, Japan was slow to take up broadband and PC-based Internet – until recently, is was mainly accessed through mobiles, which leaves much less space for innovation).

All this can and should be described in much more detail, and on this blog we will do exactly this in the next week. For us at the metadata project, Nico Nico Douga is one of the most fascinating things happening on the web at the moment: It almost seems as if on Nico Nico Douga, it is not metadata, which serves data, but data, which serves metadata. <gb>
