Lucas Pouille defeated Hubert Hurkacz 6–4, 6–3 in the first round of the ATP 250 Tokyo tournament on hard court, confirming his status as the marginal pre-match favourite with odds of 1.92 to Hurkacz's 1.97. Pouille's comfortable two-set victory demonstrated controlled tennis, breaking serve twice in each set to secure a straightforward passage through the opening round. The French player's performance suggested solid form heading into the latter stages of the season, whilst Hurkacz, the Polish prospect, offered limited resistance in what proved a disappointing outing in Japan.
