2channel (2ちゃんねる ni channeru, 2ch for short) is a Japanese textboard. In 2007, 2.5 million posts were made every day. Launched in 1999, it has gained significant influence in Japanese society, comparable to that of traditional mass media such as television, radio, and magazines. During 2008 the site generated an annual revenue upwards of ¥100 million for its founder Hiroyuki Nishimura. The website was previously operated under Packet Monster Inc., a company based in Chinatown, Singapore, between 2009 and 2014. It has been described as "Japan’s most popular online community, with around ten million users accessing it each day."

The name "2channel" is allegedly a reference to how RF modulators, commonly used for connecting earlier-generation game consoles (such as Family Computer by Nintendo) to television sets, default to VHF channel 2 in Japan.
As of October 2017, 2channel has rebranded itself as 5channel.

2ch was opened on 30 May 1999 in a college apartment in Conway, Arkansas on the campus of University of Central Arkansas by Hiroyuki Nishimura. At the time, 2channel served as the successor to an earlier anonymous textboard known as Ayashii World (あやしいわーるど). Since 2channel's servers were located in the United States, the website enjoyed a greater degree of immunity to legal action from within Japan, in comparison to its predecessors.
In 2009, Nishimura transferred ownership of the website to Packet Monster Inc., a company based in Chinatown, Singapore, while remaining as an administrator. However, due to Japanese bystander laws which state that a website holds full responsibility for the regulation of its community in the event that it becomes accessory to a crime, Nishimura was charged with promoting the sale of narcotics on December 20, 2012. Later on August 24, 2013, the Tokyo Regional Taxation Bureau declared in a tax audit that Nishimura failed to declare 100 million yen worth of website revenue which is subject to income tax.
In August 2013, an accidental leak placed the credit card details and personal details of thousands of 2channel users into the public domain, exposing the anonymous profiles of various high level personas such as politicians and writers, in addition to exposing users to identity theft. As a result, a series of lawsuits were filed against the website.
On February 19, 2014, 2channel underwent a domain name repossession, with Jim Watkins, an ex-US Army officer and chairman of San Francisco-based N.T. Technologies taking full control over the website, relieving Nishimura of all power, and assuming the role of website administrator. It was later revealed that 2channel was suffering from financial setbacks prior to the takeover. In response, Nishimura created his own clone of 2channel at 2ch.sc, scraping the contents of the entire 2channel website and costing the original 2channel website significant bandwidth costs. Currently 2ch.sc continues to scrape the contents of 2channel in real-time. In a Q&A session on 4chan shortly after becoming the site's owner, Nishimura claimed that control over 2channel was stolen by Watkins, and that he had filed a lawsuit against Watkins.
By October 2017, 2channel was acquired by Loki Technology, Inc. The site was rebranded as 5channel to avoid potential legal issues.
The website's scale and management style is unique. It has currently more than 1,000 active boards (板 ita). They are categorised such as "Social News", "Computers", and "Cooking", making it the most comprehensive forum in Japan. Each board usually has some hundreds of active threads. Each thread, in turn, contains up to 1000 anonymous comments.
2ch operates on forum software that was considered innovative at the time of its founding. It represented a major departure from the bulletin board systems of the 1980s. Everything is done anonymously and voluntarily. A posting in a thread will either bump or not, determining its position in the thread list.
Each thread is limited to 1000 postings at maximum, and a new thread must be opened (by some anonymous user, self-elected during discussion) to continue discussion. This prevents the rotting of old threads and keeps active topics refreshed. It also saves bandwidth, which is a major concern on a forum as large as 2ch. Old threads are moved to a paid archive; they are then eventually deleted.
2channel uses a referral system for any links to external websites posted on the forum. People clicking on a link are first sent to a page filled with advertisements where a link to the actual site is placed. Apart from collecting revenue from the 2channel visitors it also attracts website owners of the linked pages who check their statistics and can't link it back to 2channel.
Users will often attempt to bypass this system by removing the h from http in URLs, encouraging others to copy and paste the link, thus avoiding the referral page. For example, http://ja.wikipedia.org/ would become ttp://ja.wikipedia.org/.
One of the most distinctive features of 2ch is the complete freedom of anonymous posting. This is a large departure from most English language internet forums which require some form of registration, usually coupled with email verification for further identification of an individual. On 2ch, a name field is available, but it is seldom used. Entering one's name in the field, unless you do so with an obvious purpose, would identify you as a newbie who does not understand the forum, an administrator, or someone attempting to be a Web celebrity. However, open proxies are banned from posting on 2channel.
Slander and legal issuesEdit
The only type of posts which are not allowed are vandalism posts (for example, spamming and flooding) and posts which could be classed as slander under Japanese law, and could result in legal action being undertaken against 2channel or the poster. Also, posts which declare intentions to commit a crime would be referred to the police, due to events such as the Neomugicha incident.
In January 2007, a small court in Japan, making a judgment on yet another slander case, announced that 2channel's holding company was bankrupt and it would be repossessed. This claim was openly mocked by Nishimura on 2channel's splash page, and nothing of the sort happened, although 2channel's Japanese ISP ended its operations.
Nationalism and hate speechEdit
2channel, with its massive size and anonymous posting, is abundant with slander, hate speech and defamation against public figures, institutions, minorities, and specific ethnic groups. Though the site has a rule to delete illegal postings defined under Japanese law, the scale and anonymous nature of the site makes a prompt response difficult. On occasion, 2channel has been accused of being reluctant to remove defamatory postings. The discussion boards are also often used to coordinate real-life demonstrations; as an example, 2channel users organised an August 2011 rally against Fuji Television, under the concern that the channel was broadcasting too many Korean television shows.
Densha Otoko, "Train Man", is a Japanese movie, television series, manga, novel, and other media, all based on the purportedly true story of a 23-year-old man who intervened when a drunk man started to harass several women on a train. The man ultimately begins dating one of the women. The event and the man's subsequent dates with the woman were chronicled on 2channel.
Impact on the InternetEdit
5channel, the largest anonymous bulletin board in Japan, has various influences on society and individuals, such as becoming a source of phenomena,
In addition, it is said that most of the management team are unfamiliar with security-related knowledge, so there are few administrators for the amount of access, and they can be targets for DoS attacks and zero-day attacks. Even posting the URL of the server may result in DDoS attacks due to the concentration of user access. In any case, the overall impact on traffic load is large. For this reason, the 5channel server uses a Tyan motherboard and is installed in an Internet data center that is directly connected to the Internet exchange network "365 Main", located in San Francisco to support the network load.
Impact on the network societyEdit
5channel, the largest anonymous bulletin board in Japan, has various influences on society and individuals, such as becoming a source of phenomena, and viewers thought to be from 5channel are accessed using referrers and NG function.
Privacy and criminal activityEdit
Because of its characteristics, 5channel has some posts, including the exposure of privacy to certain individuals due to postings and slander. It is not a story that is limited to 5ch, but the Ministry of Internal Affairs and Communications revises the "defamation and privacy related guidelines" in order to deal with human rights abuse cases that frequently occur on the anonymous bulletin board, and the Ministry of Justice on behalf of the victim It has decided on a policy to allow the Human Rights Agency to request deletion. Based on these guidelines, the Human Rights Division of the Legal Affairs Bureau in each region has requested deletion of the names of minors and other minors.
On the other hand, the administrator at the time, Hiroyuki said:
We think that the privacy of the unrelated public should be unconditionally deleted regarding the disclosure of the public, but the same level of rights as the general public should be guaranteed for the suspected suspect of the offender I do not think.
In addition, if privacy at the same level as the general public is guaranteed, there are victims whose privacy has been disclosed in addition to the criminals of this time, and equivalent relief measures should be taken for those people as well. think.
If it is the legal bureau's idea to put relief measures for the general public and give priority to the relief measures for the suspects, we are ready to follow, but we would like to have a clear answer on this matter.
Hiroyuki also did not respond to the request (the Ministry of Justice did not give a clear answer to this).
Crime notice and post monitoringEdit
Since the Nishitetsu Busjack Incident the police will be warned if there are any posts that are a notice to a crime the poster will commit and those are arrested, if there is a major case, the relevant agency is checking the relevance of the killing and attack notice and the case frequently written on boards. The police agency's cyberforce regularly searches and monitors posts. In addition, even if it is a trivial crime notice written that apparently seems to be a mischief purpose, another user may notify the operation side and lead to an arrest or etc, and the crime notice is prohibited. The fact that it is a crime notice does not touch the deletion criteria for 5ch and it is treated as a matter of evidence preservation, so even if it is requested to delete a crime notice, it is not deleted at first. However, on some boards where surveillance is frequently conducted, measures have been taken to forcibly stop the thread that the administrator has judged as a crime notice.
Furthermore, it is also said that a large number of companies, mainly large companies, are increasing the number of companies that have specialized departments for monitoring them so that they will not be disadvantaged by false or malicious writing. In fact, a major advertising agency, Dentsu, has entered into a business alliance with Gala, and offers an ASP service “Dentsu Buzz Research” that monitors and reports on company posts on bulletin boards to client companies for a fee (105,000 monthly) Yen (tax included) / 1 client).
It is regarded from the beginning as a problem, and by around 2005 there was a statement at the bottom of the top page to draw attention to it.
Children in 2channelEdit
Some children's search sites, such as Kids Goo, are filtered, and the filtering software is in the "BBS" category.
According to a survey released by Web filtering company Net Star in February 2007, the result of “The utilization rate of 2channel for primary and secondary students is 12.2%”  has been obtained, and primary and junior high students There is a statistics that more than 10% of are 2channeler.
Contribution to the fairness of academic researchEdit
In the academic papers such as medicine, indications of suspected fabrication have been made on a board continuously since around 2000. There are also documents that evaluate that many writings are tapping into the nature of the problem
There are boards of any and all themes regardless of genre, and the information to be exchanged is very diverse. There are also boards used as sites where consumers and engineers exchange information on products, services and technologies, and there are also academic categories used for academic discussions. However, it is hard to say that it's functioning exactly as "a place of fair and genuine information exchange" or "a place of academic discussion" in a strict sense.
In addition, as an example of academic contribution, there is a case that contributed to the discovery of the construction of human embryonic stem cells (ES cells) by Korean jaundice (December 2005) in the case of a bulletin board in Korea. It has also contributed to the publication and resolution of server access concentration problems (January 2005).
It is also used as an information storage and provision site at the time of disaster etc. In the Niigata Chuetsu Earthquake in October 2004, it was used to provide information centered on the individual level together with Yahoo! Bulletin Board and earthquake information summary site etc. [68 ]. Special plates for earthquakes such as earthquake bulletin boards are always open.

This single site has more influence on Japanese popular opinion than the prime minister, the emperor and the traditional media combined. On one level, it serves as a fun, informative place for people to read product reviews, download software and compare everything from the size of their poop to quiz show answers. But conversations hosted here have also influenced stock prices, rallied support for philanthropic causes, organized massive synchronized dance routines, prevented terrorism and driven people to their deathbeds.

2channel was based on a previous text board called Ayashii World, the first big anonymous text board in Japan... Ayashii World, like many anonymous chan boards, experienced so much downtime that its owner began to receive death threats, prompting him to shut down the board in 1998.

But Channel 2 is also a window into Japan's ugly side. Many of the contents tend to be nationalistic and xenophobic, especially toward Koreans. When Sony and Samsung recently announced a joint project, users attacked Sony for cooperating with the South Korean company. "Die, Sony!" read several comments. "Die, Koreans!"
