Argentine network TyC Sports shared a video of the kind act, saying that instead of celebrating the victory Senegalese fans showed respect by cleaning up their sector. But those working after Japan's games will have an easier job of it. Following their full-voiced support, the FIFA World Cup named Senegal as "fans of the day".
Japan-based soccer writer Scott McIntyre told the BBC that cleaning up after yourself following a sporting event was "not just part of the football but part of Japanese culture". The freaky, but generous, gesture is reportedly part of Japanese culture and came after Japan got their World Cup campaign off to a ideal start on Tuesday.
Halilhodzic had led the side to their sixth consecutive World Cup finals but concerns about the direction the team was going prompted the JFA to replace him with Akira Nishino, giving the new coach 71 days to prepare the side for Russian Federation. It is a habit drilled into citizens from a young age, with students expected to clean their school classrooms and hallways.
People on Twitter also praised their efforts. The team's prospects this year now look far more encouraging.

The Pharaohs qualified for the World Cup for the first time since 1990, and had high hopes in the lead-up to the tournament. Nobody would seriously dispute it; proving it again now might just be his biggest achievement yet.
In the World Cup, Japan became the first Asian team to win against a South American opponent by beating Colombia 2 to 1.
The footage comes after Senegal fans in the other Group H encounter did exactly the same in Moscow later on Tuesday evening.
Indeed, there were similar scenes over at the Mordovia Arena in Saransk, where Japan fans spent their time politely tidying up after themselves in the wake of their side's 2-1 win against Colombia.
Not bad, Senegal and Japan.
