Hijikata beat Russia's Pavel Kotov 7-5 5-7 6-3 7-5 in a bruising four-hour battle that put him through to the second round at Flushing Meadows.
However, his joy was cut short by news of the shooting death of a faculty member at the university, where Hijikata's girlfriend is still taking classes.
"I came off the court and saw there was a shooting at UNC that's kind of put a dampener on it (win)," said Hijikata.
"I guess it is just the reality of life sometimes in this country, which is not a good thing."
"I feel like it is really not an unexpected event, which makes it worse almost.
