In an operation starting Tuesday this week and ending Friday, police targeted 50 locations around Japan and ultimately arrested a total of 18 individuals.

The ACA, an organization made up of various trade groups including the Recording Industry Association of Japan, International Motion Picture Copyright Association and various other film, music and software entities, said the raids followed a similar but smaller operation in November last year. In that action, 11 people were arrested and according to ACA, all have been convicted.

As appears to be customary in these cases, the RIAJ – the Japanese equivalent of the RIAA – has taken the step of publishing a list of the ages, sex, locations, occupations and copyright works said to have been shared by the 18 individuals.

They range from a 25 year-old taxi driver from Tokyo sharing Cross Game, Dragon Ball Kai, Evangelion, Fullmetal Alchemist: Brotherhood and Gundam 00 Second Season, to a 58 year-old construction worker sharing IBM Homepage Builder 12 and input method editor ATOK 2010.

What is striking about the arrests is that none of the accused appear to be heavy uploaders – the ‘worst’ pair appear to have uploaded 6 games, 2 comics and 4 music tracks between them.

While downloading in Japan was previously permitted for personal use, both up and downloading of copyright works are now expressly illegal.

This download trend has not gone unnoticed by the local police either, who recently arrested an unemployed man for sharing 165 TV-shows on BitTorrent.

The 31-year old Shuichiro Tanaka was arrested by Tokyo Police’s Cyber Crime unit and was charged with recording and uploading 3 TV-shows in early June. According to reports, Tanaka also shared 165 more TV-shows between February and July this year.

The videos the man shared on BitTorrent were mainly Japanese variety shows such as “Waratte Iitomo” and “Genius! Shimura Zoo.” According to the police, this is the first time that someone was arrested for copyright infringement on BitTorrent in Japan.

Tanaka has confessed to the charges and stated that he used BitTorrent to avoid running into viruses and the police.

“I did it for people who missed the TV-shows. Because there is a potential for viruses on Winny and others, I used BitTorrent, which I heard police weren’t investigating,” Tanaka told the police while pleading guilty.

Unlike on BitTorrent, viruses are both prevalent and quite aggressive on the Winny network. One virus that surfaced three years ago was specifically targeted at file-sharers and threatened to report them to the police, or kill them if they continued sharing.

Although this is the first arrest of a BitTorrent user, it is certainly not the first file-sharing related case. Last year, a 33-year old Japanese man was arrested for uploading the movie ‘Wanted’ to the Winny network before its Japanese theatrical release. He was later sentenced to two years in prison.

Now it is the turn of Japan to target a pre-releaser, this time of the movie ‘Wanted‘. The movie, starring James McAvoy, Morgan Freeman and Angelina Jolie, was released early September in the United States and Europe, but won’t enjoy an official Japanese release until Saturday. The movie is, of course, already available for download on P2P networks in its native English, but thanks to the work of Kazushi Hirata, a 33 year-old from the city of Sendai, the movie is also available with Japanese subtitles.

According to the authorities, after adding his own home-made subtitles to an already-released pirate version of the movie, Hirata uploaded it onto the Winny network, which is hugely popular in Japan. Hirata was tracked down on Thursday by the Kyoto Prefectural Police, who were also responsible for the 2004 arrest of Isamu Kaneko, the creator of the Winny software.

The arrest of Mr Hirata is believed to be the first in Japan relating to the uploading of a pre-release movie. According to a report, he faces up to 10 years in jail and a $95,000 fine.

The Winny network has always been touted as anonymous, and indeed functions on this level to a degree. The police were unable to crack the encryption used by the file-sharing part of the software, however, they did manage to exploit a loophole to identify certain users. Winny’s forum feature fails to protect the anonymity of people who start discussion threads. In the past the police have searched for copyright material in such threads and recorded the IP address of the poster. By initiating a file-transfer but denying connections from all IP addresses apart from the suspected infringer, when someone started to upload to them they knew that the original poster was sharing the illicit material.

Now, under huge pressure from the movie, music and software industries, the four major ISP organizations in Japan are at it again, and have agreed to take drastic action against online pirates.

According to the report in Yomiuri Shimbun, the agreement would see copyright holders tracking down file-sharers on the Internet using “special detection software” and then notifying ISPs of alleged infringers. ISPs would first send out emailed warnings to those traced, then interrupt the Internet connection if action to cease the activity isn’t taken. For persistent breaches, the ISP would ultimately terminate the accounts of its subscribers.

These four major ISP organizations – which include Telecom Service Association and the Telecommunications Carriers Association – are made up of around 1,000 other ISPs, a large portion of the Japanese market. In collaboration with the copyright holders, the ISPs will set up a panel in April to decide exactly how the system should operate.

Right now, there is a lot discussion surrounding the suggestion that persistent file-sharers could be banned from the internet. So far there have been proposals in France, the UK and Australia.

During December last year we reported that the number of internet users file-sharing in Japan had increased by a 180% in a single year.

However, since BitTorrent is the best p2p protocol to distribure large files, it still generates almost 50 percent of the p2p traffic according to chachelogic’s data.
