Outside of the marathon, Japan's best hope for a track and field medal is hammer thrower Koji Murofushi. Another Koji -- Ito -- may not have a chance at a medal, but he could make some history in the 100 meters.

At 187 cm and 90 kg, the 25-year-old Murofushi will be one of the smaller competitors in the hammer throw. But what Murofushi lacks in size, he makes up for in style.

Murofushi comes by his technique honestly. He learned it from his father Shigenobu, the hammer throw champion at five consecutive Asian Games from 1970-86. The elder Murofushi was on hand at the 1998 Asian Games in Bangkok to watch his son add another gold medal to the family trophy case.
