Career
She was the 200 m gold medallist at the 2009 Asian Athletics Championships. A Japanese junior record holder, she is the country"s second fastest ever runner over both 100 metres and 200 metres, behind Chisato Fukushima. Her bests for the events are 11.32 seconds and 23.15 seconds, respectively.
She is a joint holder of the Japanese record in the 4×100 metres relay.
In 2006, she established herself with a Japanese junior and high school record of 11.54 seconds for the 100 metres. A third place in the event at that year"s Japanese Athletics Championships brought her selection for the 2006 Asian Games.
Takahashi claimed her first national title at the 2007 Japanese Championships, reaching the top of the podium in the women"s 100 m. She competed at the 2007 Summer Universiade and ran the 100 m individual and relay events at Osaka"s 2007 World Championships in Athletics, although she did not make it past the heats in either competition.
The 2008 season was not as productive for her, as she was fourth nationally and did not get selected for the 2008 Beijing Olympics, but she did improve her 200 m best to 23.48 seconds.
Competing on the world stage for a second time, she ran in the heats of the 100 m, 200 m, and 4×100 m relay of the 2009 World Championships. Takahashi also set her first Japanese national record that year, as she anchored home a 4×100 m relay team of Saori Kitakaze, Fukushima and Mayumi Watanabe in a time of 43.58 seconds at the Osaka Grand Prix. She was one of the Asia-Pacific team"s representatives at the 2010 IAAF Continental Cup, but she finished last in the 200 m, while the Japanese women"s relay team that she anchored met a similar fate.
She did not manage an individual medal at the 2010 Asian Games in November (coming fourth and sixth in the 100 m and 200 m finals), but she helped a Japanese quartet claim a bronze medal in the short relay.
Her 2011 began with a new national relay record at the Seiko Golden Grand Prix, where she, Saori Kitakaze, Fukushima and Kana Ichikawa knocked nearly two-tenths off the previous time with their run of 43.39 seconds.
