The opening day of main draw action at the ATP 500 Japan Open in Tokyo delivered high-octane tennis, intense drama, and early surprises in the round of 32. The first four matches are officially complete, treating spectators at the Ariake Colosseum to commanding performances from established contenders, gritty comebacks, and the first major upset of the week.
Round of 32 Match Results
In an all-French showdown, qualifier Arthur Fils maintained his winning momentum by brushing past compatriot Luca Van Assche with a convincing 6-3, 6-2 victory. Fils entered the main draw via the qualifying rounds despite rising to World No. 9 in the ATP rankings this week, a position that would have normally earned him the No. 3 seed. This unusual circumstance was caused by an administrative hesitation from his coaching camp, which weighed entries between Tokyo (where Fils triumphed in 2024) and Beijing for too long. By the time the call was made, the entry cutoff had passed, leaving the Frenchman with the choice to either skip the event or fight through the qualifying draw. Opting to earn his spot on the court, he validated that decision with a dominant display in his main-draw opener.
The biggest upset of the day came courtesy of Chile’s Alejandro Tabilo, who dismantled the favored Tommy Paul in a lopsided 6-1, 6-2 contest. Tabilo established complete control from the baseline, consistently attacked the American’s delivery, and secured his place in the round of 16 in under an hour.
Italy’s Matteo Arnaldi mounted a resilient comeback to overcome promising Japanese wildcard Rei Sakamoto. The young local talent dominated the opening set to take it 6-2 in style. However, Arnaldi stabilized his baseline depth, secured a decisive break of serve in each of the subsequent sets, and closed out the match 2-6, 6-4, 6-4.
A closely fought encounter saw Monaco’s Valentin Vacherot edge past Belgium’s Alexander Blockx 7-6(2), 7-6(4). Blockx, fresh off a breakthrough quarterfinal run at the US Open where he was halted by Karen Khachanov, delivered stubborn resistance, but Vacherot produced the steadier tennis in both tiebreaks to seal the win.
