She skipped her own team in Sapporo, Hokkaido, until 2015, which represented Japan at the 2014 Winter Olympics before retiring from competitive sports.

At the age of 12, Ogasawara began curling in her hometown Tokoro, joining Akiko Katoh's junior team together with Yumie Hayashi.

After the 2001-2002 season, Ogasawara and her longtime teammate Hayashi moved to Aomori and formed a new team there.

At the Games, Ogasawara threw last stones as skip and led her team to a 7th-place finish with a 4-5 record, including a surprise win over one of the usual curling powerhouses, Canada.

In 2011, Ogasawara and Hayashi, whose name had changed to Yumie Funayama after marriage, formed a new team in Sapporo.
