Atsuki Ito scored his maiden international goal, and Keito Nakamura added two more before halftime as Japan secured a 4-2 friendly win over Turkey on Tuesday.
Ozan Kabak pulled one back for Turkey to make it 3-1 late in the first half, while Bertug Yildirim further cut into Japan's lead before second-half substitute Junya Ito sealed the result from the penalty spot.
Japan's victory at the home of Belgian Pro League side KRC Genk followed its 4-1 dismantling of Germany on Saturday, which prompted the firing of Hansi Flick as head coach of the four-time world champion.
