Former Olympic hammer champion Koji Murofushi has urged Japan's athletes to embrace the pressure of the 2020 Tokyo Games and end the country's track and field gold drought.

Murofushi won Japan's last athletics gold at the 2004 Athens Games when he was bumped up to first place following the disqualification of Hungary's Adrian Annus for a doping offense.

Japan will try to end its lean spell in Rio de Janeiro in 2016, but Murofushi, who also won Olympic bronze in London two years ago, believes the Tokyo Games will offer a unique opportunity for those brave enough to take it.
