What are the ppl standing around in pontocho doing at night?

For context, I was walking around pontocho on a Saturday night when there was a ton of foot traffic. In several intersections I saw groups of 2-4 young ppl wearing similar clothing (black hoodies/puffers, skinny jeans, Air Force ones). They seemed to be smoking and standing around while looking at everyone passing by as if they’re looking for something in particular.

I passed by several intersections like this and my first thought was that they might be trying to bring folks to other establishments but not once did I see them approach anyone. I know there are touts in places like kabukicho but I didn’t see these ppl approach anyone.

Just curious if anyone know what they’re looking for/doing?

Edit: In hindsight I could’ve worded the question better. In no way am I insinuating they shouldn’t be there doing whatever they want. I was genuinely just curious if there was something cool/hidden I might’ve missed. Thanks for all the replies folks.

Edit again: It looks like they were actually touts promoting biz. I walked back that way after dinner 2 nights later when there was way less foot traffic and was approached ~5 times. My guess is that when there’s way too much foot traffic they might not approach ppl so as not to cause congestion or maybe they already have a lot of business on those nights
