2channel, often called 2ch or Channel 2, is a massive anonymous Japanese textboard. A textboard is an online forum where users post messages in organized threads. Founded in 1999, it became one of the most influential online communities in the world. By 2007, its impact on Japanese culture was comparable to traditional mass media like television or radio. At its peak, the site saw roughly ten million visitors. It also processed about 2.5 million posts every single day.

The site operates using a system of anonymous posting. Unlike many English-language forums, 2channel does not require users to register with an identity or email. Founder Hiroyuki Nishimura designed it this way to encourage unfettered expression. He believed that using real names leads to personal attacks and social hierarchies. In an anonymous system, users focus on the argument rather than the person. This approach ensures that all information is treated equally. This unique structure later inspired the creation of other famous sites, such as 4chan.

Technologically, 2channel evolved from earlier internet tools like Usenet and dial-in bulletin boards. It was preceded by two specific Japanese sites: Ayashii World and Amezou. Ayashii World was Japan's first large anonymous web bulletin board. Amezou introduced the chronological textboard concept. In this system, new comments "bump" older threads to the top of the list. Nishimura launched 2channel on May 30, 1999, from a college apartment in Conway, Arkansas. He marketed the site as "Amezou's second channel." Hosting the site in the United States allowed it to bypass strict Japanese censorship rules.

As the site grew, it faced significant legal and social challenges. The anonymity that provided freedom also allowed for harmful behavior. The site became a hub for the netto-uyoku, or extreme right-wing users, who often posted xenophobic comments. By August 2008, Nishimura had faced over one hundred lawsuits regarding defamation. Defamation occurs when users post comments that damage a person's reputation. In 2012, the Tokyo Metropolitan Police investigated the platform for allegedly allowing amphetamine dealers to operate. While no charges were filed against Nishimura, the investigation highlighted the difficulties of moderating anonymous spaces.

In August 2013, a major security breach occurred via a paid service called the Kako Log. This service allowed users to pay to read old, archived threads. A hacker accessed the logs and leaked the personal data of over 74,000 users. The leak included names, addresses, phone numbers, and credit card details. This exposure was particularly sensitive because it revealed the identities of high-level personas, including politicians and writers. Jim Watkins, the site's hosting provider, described the event as a cyber attack that compromised customer data.

A major ownership dispute caused the platform to split into two separate entities. In February 2014, Jim Watkins seized the 2ch.net domain. He took full control of the website and removed Nishimura from power. Watkins claimed this was necessary to settle debts owed to him. Nishimura disagreed, calling the move an illegal domain hijacking. In response, Nishimura created a clone of the site called 2ch.sc. This resulted in two different boards both claiming to be the legitimate 2channel.

The legacy of 2channel continues through its various successors. One version eventually transitioned to 5channel to avoid legal conflicts regarding the 2channel trademark. As of July 2020, 5channel hosted 1,031 boards with approximately 2.7 million posts on weekends. Another successor, 2ch.sc, maintained 826 boards with about 5,700 daily posts. These platforms remain massive hubs for diverse topics, ranging from sports and celebrity gossip to academic research. They represent a complex chapter in the history of how people communicate globally through the internet.
