The all-night expo in Japan showcases outstanding hospitality services ("神対応") from participating countries. This cultural convergence, known for running throughout the night, offers a unique opportunity for countries to display their expertise in the hospitality industry. With diverse culinary experiences and cultural spectacles, the event has drawn a significant amount of interest and praise from attendees.

This event is significant in Japan as it serves as an avenue to showcase the country's renowned hospitality ("Omotenashi") while learning from other countries. The Japanese people value exceptional customer service and take pride in it; thus, such events have an important place in the society. It also encourages international relations and cultural exchange.

In the U.S or EU, such events could be equated to a world's fair or international expo that typically celebrates diversity, fosters international relations and promotes culture. They are a melting pot of different countries coming together to share experiences and cultures.
