In September 2012 the Japan Anti-Doping Agency (JADA) has reported an anti-doping rule violation against the Athlete J-4135 (the Athlete) after his sample tested positive for the prohibited substance furosemide. After notification a provisional suspension was ordered. The Athlete filed a statement in his defence and he was heard for the Japan Anti-Doping Disciplinary Panel.
The Athlete stated that he has used a herbal medication purchased on the internet as treatment for his insomnia.
Considering the Athlete's negligence and his statement the Japan Anti-Doping Disciplinary Panel has his doubts that the use was non intentional and decides on 28 September 2012 to impose a 2 year period of ineligibility on the Athlete starting on the date of the provisional suspension, i.e. on 18 September 2012.
