TOKYO (Reuters) - Japan's Hiromi Miyake knows weightlifting powerhouse China will be looking to dominate the event at the 2016 Olympics but the London Games silver medallist says her biggest rival in the run-up to Rio is herself.

The 30-year-old, who will compete in a fourth Olympics, hails from a Japanese weightlifting dynasty. Her uncle Yoshinobu won gold at the 1964 and 1968 Games, while her father and coach Yoshiyuki took bronze in 1968.
