### Davis Cup

To date, Soeda has compiled a 26–12 win–loss record overall (24–10 in singles and 2–2 in doubles). He received the Davis Cup Commitment Award in April 2014.
In the first round of 2012 Davis Cup World Group against Croatia, Soeda faced Ivan Dodig in the first singles rubber and defeated him in a 4 hour, 5 minute match. This victory was Japan’s first win in a World Group match (In their previous two World Group matches, Japan lost 0–5). He was beaten by Ivo Karlovic in reverse singles, and Japan lost 2–3. He scored another notable win in the 2013 Davis Cup World Group play-offs against Colombia. He lost to Santiago Giraldo in five sets, but defeated Alejandro Falla in the deciding rubber to put Japan back in the World Group for 2014.

## Playing style

Soeda is an offensive counterpuncher. Due to his relatively small size (5'10"), Soeda lacks the power and stature to effectively dictate points. Instead, he relies on quickness to retrieve opponent's shots, as well as a relatively flat, penetrating two-handed backhand. As noted by commentator Nick Lester in the BB&T Atlanta Open, Soeda plays a conventional style of tennis, approaching and finishing points at the net when possible.
