Matsumoto likes groundwork and never hesitates to take the fight to the ground. Most of the time, she's attempting some form of osaekomi roll but she is capable of doing strangles and armlocks. She just doesn't do them that often. One strangle she seems to prefer is koshi-jime, which she uses against opponents who try ippon-seoi-nage on her. Here in this video, you can see her strangle her rival Monteiro of Portugal twice with the same technique.
