Sapporo Half Marathon
She started out as a 10,000 metres track runner but she changed to road running at a relatively young age. She set a half marathon best at the 2002 Miyazaki Women's Road Race, where her time of 1:09:28 brought her third place behind Mizuki Noguchi and Mikie Takanaka. Running at the Sapporo Half Marathon in 2003 she finished with a time not far from her personal best (1:09:37) to take second place behind Catherine Ndereba, who set a course record. Over this period she competed at the IAAF World Half Marathon Championships and although she failed to finish at the 2002 edition, she managed 19th place the following year.
