Arthur Fils overcame a tense opening match at the 2026 Kinoshita Group Japan Open Tennis Championships on Wednesday, defeating fellow Frenchman Luca van Assche 6-3, 6-2 in Tokyo. The straight-sets victory at the ATP 500 event secured the newly minted world No. 9 an expedited path into the second round after a demanding week of qualifying matches.
Qualifying Pressure Tests the New Top 10 Standing
The journey to the main draw at the Ariake Colosseum proved unusually complicated for Fils. Following an opening-round exit at the US Open against Stefanos Tsitsipas, scheduling missteps left the Frenchman’s entry status unresolved. Deciding whether he would travel to Tokyo remained uncertain for several days until a late registration window closed just six or seven hours too tardy.

Fils and his team opted to take on the tournament’s qualifying rounds. That decision forced the newly established top-10 player into a position of high vulnerability. Wins against American Martin Damm and Poland’s Kamil Majchrzak in three sets each secured his spot, but the process created heavy mental strain. Fils admitted to tournament organizers that competing in qualifiers as a top-10 seed and a former champion of the event created a scenario where a loss carried severe psychological weight.
A Comfortable Reunion Against a Lifelong Friend
Wednesday’s first-round encounter offered a stark contrast to the anxiety of the qualifiers. Matched against childhood friend and compatriot Luca van Assche, Fils found a calmer mindset on the court. The pair have known each other through years of junior development in France, making the tour-level meeting a rare occasion. Fils converted his second match point to seal the win in one hour and 34 minutes.
Following the match, Fils praised his opponent’s trajectory, noting that van Assche is enjoying the finest season of his professional career so far. The victory advanced Fils past the world No. 43 and set up a compelling test for his next appearance in the Japanese capital.
Next Opponent and Tournament Outlook
With his opening-round victory secured, Fils turns his attention to the second round of the ATP 500 hard-court tournament. He is scheduled to face either home favorite Kei Nishikori or former US Open finalist Frances Tiafoe. The clash will test the French player’s stamina as he looks to replicate his title-winning run from the 2024 edition of the Tokyo tournament.
