A surge of outdoor barbecue enthusiasts is troubling locals in Japan, leading to multilingual warnings. These warnings, now available in 16 different languages, signify the escalating concern amid residents over the influx of BBQ goers. The main issues include noise, trash, and smoke affecting the lifestyle and tranquility of the local people. The situation is prompting a discourse on social conduct, public spaces usage, and cross-cultural understanding.

Japan, known for its social harmony and respect for public spaces, values cleanliness and orderliness. Disrupting these societal norms is seen negatively. Though enjoying BBQs in public spaces is not illegal, the disturbance it causes in residential areas is a concern. Barbecues are largely considered a summer activity, thus this issue heightens during that season, with residents and authorities making attempts to manage it effectively.

In the US or EU, public BBQs are also a common issue, especially in park areas near residential neighborhoods. Authorities in these regions also use signage in multiple languages to communicate public behavior codes. However, the seriousness given to respecting public space, noise, and cleanliness may differ based on cultural variations.
