He is not even on the bench for Augsburg today. As for other Japanese players: Kagawa back from injury and on the bench for Dortmund and both Haraguchi and Gotuko Sakai on the bench for their teams. While Muto and Asano are both starting for their teams (It is Asano's Bundesliga debut).
No reason for pessimism, as @Dax said it is all expected except Gotoku's start at the bench. Both Haraguchi and Kagawa came late as subs in the second halves to help their teams winning their first B1 games. Full 90 minutes for Asano and Muto. Kagawa is back in time after his injury for the upcoming WC qualifiers. Nothing to worry about.
