Hasegawa was a famous exponent of heavy topspin forehand attack, combined with lob defence. He used a modified shakehands grip with the index finger pointing down the center of the blade. This made his backhand a little awkward for fast attack, so even though a shakehander his tactics were similar to the Japanese penholders with wonderful footwork.
Hasegawa died while felling trees near his home and was buried under a tree.
