Japanese-Brazilian 400-meter hurdler Mahau Sugimachi has been training hard in the run-up to Rio's 2016 Olympics, in the hope of securing a place in the final. It would not only be a personal achievement — he says it would give a boost to fellow Japanese living there.

Although the 31-year-old Brazilian national will represent his country in Rio, he says he will aim to demonstrate his gratitude to Japan, where he has lived for 23 years.

Sugimachi reached the quarterfinal at the 2008 Olympics in Beijing but failed to win a ticket to the 2012 Games in London.
