Mami Ishino (石野 真美, Ishino Mami, born 10 January 1983) is a Japanese track and field athlete who specialises in the 100 metres hurdles. Her personal best for the event is 13.08 seconds.
She secured her first national title in 2006 and was also runner-up at the Corporate Championships and Japanese Games.[5] Ishino won a second, consecutive national title the following year and also topped the podium at the 2007 Asian Athletics Championships with her time of 13.26 seconds.[6][7] She won the titles at the corporate meet and the National Games as well.[8] She made her global debut at the 2007 World Championships, but did not get past the heats stage.[9]
In 2008, she found herself finishing behind teenager Asuka Terada at both the national championships and the national games.[10] She opened 2009 with a win at the Oda Memorial.[11] She again was beaten by Terada at two competitions, coming second in the Japanese championship and missing the medals at the 2009 Asian Athletics Championships (Terada was runner-up). Ishino did manage to win at the Japanese Games and Corporate championships that year.[2] She was the silver medallist behind Sun Yawei at the 2009 East Asian Games in December.[12]
Ishino retained her corporate title in 2010, but was third at the Japanese Championships and Games and did not compete internationally.[13] For the first since 2004, Ishino failed to reach the top three at the 2011 Japan Championships in Athletics and also had to settle for third at the corporate meet and the Japanese Games. Her form continued to diminish in 2012 and 2013, as she failed even to reach the national finals in the 100 m hurdles.[2]
