Lawsuits
As defendant
Nishimura has lost a number of libel lawsuits which have led to him being assessed a considerable amount in penalties. In 2008, he told Wired he has no intention of paying, saying, "If the verdict mandates deleting things, I'll do it," but, "I just haven't complied with demands to pay money. Would a cell phone carrier feel responsible when somebody receives a threatening phone call?"<!--The Watkinses have claimed to have appealed and won in either the Tokyo High Court or the Supreme Court of Japan, but as I've not been able to find the judgment, I'm not sure if it's executory/final or not, or if it even exists. Also, they're obviously biased towards the strength of their case, so might not be reporting Court processes accuracy for whatever reason. So, their WP:SPS's should not be added, only third party verifications. They are of course free to share the judgment with the world if it exists.--> Through the Japan Patent Office, Nishimura owns the trademark "2channel", though the WIPO refused to intervene on his behalf on account of that, suggesting the parties go to court instead as it was not, in its view, a case of "cybersquatting" but rather a "business dispute".
