Kicking off the excitement for the upcoming Expo events in Tokyo, numerous enthusiasts made their way in lines overnight to partake in related activities. This phenomena underscores the Japanese public's high anticipation and engagement with Expo, which contributes to Japan's vibrant cultural scene. It is noteworthy how phenomenally these events draw people in, sparking mass participation even during late-night hours.

In Japan, lining up overnight for major events or exclusive sale merchandise is quite common. This is a part of the Japanese culture known as "Gyōretsu no dekiru mise", meaning "stores that have very long lines". The social value involved here is patience and tenacity, as people willingly queue for lengthy periods with grace and discipline.

In contrast, overnight queuing is less frequent in the US or the EU. Though it's used for major events or product launches, it is often met with less acceptance as it can lead to crowd management issues or health and safety concerns. However, it is still notable in fandom culture for concerts or convention-related events.
