The 29 year old threatened Hudson 11 times from October 2008 to January 16, 2009.
He sent emails that said things like he was sending a bomb to the company that would kill everyone or demanding that 80 trillion yen be brought to JR Takamatsu Station.
The scary part is the suspect thought his bomb threats would make Hudson improve the quality of their games.
