Senegal brought in midfielder Badou Ndiaye in place of Stoke City team-mate Mame Biram Diouf while Japan named an unchanged side for Sunday's World Cup Group H match.
The experienced Keisuke Honda and Shinji Okazaki, who both came on as substitutes in Japan's 2-1 win over Colombia, remain on the bench, with Yuya Osako leading the attack on a bright sunny evening in Yekaterinburg.
Senegal also won their first match 2-1 against Poland, and a win would see them advance to the last 16 if Colombia fails to beat Poland later in the day.
