Universal Studios Japan (USJ) has imposed a prohibition on bringing in outside food. This policy, which is not uncommon among theme parks, has been strictly implemented at USJ to ensure the safety and hygiene of food consumed within the premises. It also aims to create an immersive experience for visitors and to support the internal food providers. The precise date for this change is yet to be announced.

In Japan, people are accustomed to following rules in public places, especially at theme parks. The food safety rules are seen as an essential part of maintaining hygiene and ensuring a pleasant experience for all visitors. Furthermore, catering providers within theme parks, who often offer theme-based foods and beverages, comprise a significant part of the park's revenue and attraction.

In the US and EU, food policies in theme parks vary. Certain parks, like Disneyland, allow visitors to bring small snacks but restrict larger meals. The intent is similar to USJ's—to maintain safety and hygiene while also promoting on-site food services.
