A neighborhood association is an organization for the residents living in the same area to carry out activities aimed at creating a better community to live in. It is called chônai-kai or jichi-kai.
One of the main activities is keeping the neighborhood clean, as mentioned in the skit. Other activities might include planning and organizing the local summer festival or fireworks event so that the local residents can have a feeling of unity.
A chônai-kai may also organize disaster drills in preparation for a major earthquake and operate patrols to help prevent crimes.
