^^ They're in Doutonbori, which is in Namba district. That's probably Osaka's most famous street? That white advertisment which has a running man drawing is probably the most famous landmark of the district as well.
Anyway, it's a shame only high schoolers get to travel (by skipping school, middle schoolers and lower aren't allowed)... it'd be great if you could bend the rules a little if it's about idols
