Matsudaira became well known on the world stage after his match against the Olympic champion Ma Lin at the 2009 World Table Tennis Championships, where he demonstrated his advanced tomahawk serves, compact and explosive technique, alongside his dynamic backhand control. He won two straight games from a 1–3 deficit and held the lead at 4–1 in the seventh (he lost the set 11–9). Later, he beat Ma 4–1 at the 2013 World Table Tennis Championships in the Round of 64. After progressing to the Round of 16 and beating Vladimir Samsonov 4–3, he lost in the quarter-finals to the bronze medalist, Xu Xin, in 6 games. This is regarded as his best performance in his adult career and was considered to have performed the best out of all of the non-Chinese players. He is ranked 17 in the world as of January, 2017.
