The Japanese parliament enacted Friday a revised anti-online piracy law to tighten copyright control, banning illicit downloading of manga, magazines and academic texts, in addition to music and videos that were already covered by the existing legislation.
The law also regulates "leech websites" that provide users hyperlinks to download so-called torrent files of pirated materials. The ban on illegal downloading will take effect on Jan. 1 next year, while restrictions on leech sites will come into effect on Oct. 1.
The law revision came as the country saw a rising number of piracy and leech websites, notably the Mangamura site, which had over 100 million hits a month before being disabled in April 2018, causing an estimated loss of more than 300 billion yen ($2.75 billion) to publishers.
Mangamura hosted unauthorized copies of popular manga titles, including "Attack on Titan" and "One Piece."
However, the amended legislation exempted "minor offenses" and "special instances" from being categorized as illicit amid concerns that excessive restrictions could hinder internet use and freedom of expression.
The Cultural Affairs Agency lists examples that can be exempted, such as downloading only a few frames from a comic book of several dozen pages and a couple of pages from a novel containing several hundred pages.
Parodies or derivative works are also exempt, as well as cases where smartphone users unintentionally captured copyrighted publications in their screenshots.
As for illegal downloading, penalties for repeat offenders will be up to two years in jail or a maximum fine of 2 million yen ($18,320), or both.
The new law also bans establishment and operation of leech sites, pasting hyperlinks of illegal websites on an anonymous message board, or providing "leech apps" for similar purposes.
Those found to be operating a leech website will face penalties of up to five years in jail or a maximum fine of 5 million yen, or both.
Last year, the government tried to submit a similar anti-online piracy bill to a parliamentary session but shelved it after receiving backlash from manga artists and experts who said the planned controls were too broad and could hinder legitimate activities such as research.
As of last November, there were more than 500 piracy websites featuring manga and photo books targeting Japanese viewers, with the top 10 sites getting some 65 million hits a month. Seven of them provided download links, according to Publishers PR Center.
A senior official of the agency said the new legislation is expected to have a "significant deterrent effect," as research by an industry group shows existing legal restraints on illegal downloading of music and videos had positive effects.
An online poll by the agency also found around 90 percent of respondents said they will stop using, or use less frequently, piracy websites if downloading from those sites becomes illegal.
Loopholes remain, however, as videos showing copyrighted items in the form of a picture-story show or provision of such materials through streaming -- as was the case with Mangamura -- are not covered by the revised law as they do not involve downloading data to devices.
Also, many piracy site operators use servers overseas where rules are lax. So-called "bulletproof hosting" services that are lenient about what can be hosted on their servers and warrant high confidentiality hinder requests for information disclosure.
A site-blocking measure to forcibly deny access to certain websites is also difficult to implement in Japan, as it requires subscribers' access data and could violate the privacy of communication.
"There's a limit to what Japan can do on its own. International coordination and cooperation in investigations are indispensable," a government source said.
