The headline highlights the last day of unrestricted panda viewing in a prominent Japanese zoo. This day marked the end of an unusually long period during which visitors were allowed to observe pandas without prior reservations. The event drew many locals and tourists, eager to seize the rare opportunity before it ended. Lines to see the pandas stretched back for significant distances, indicative of the animals' popularity.

In Japan, such events draw significant attention due to the high regard for pandas and their symbolic importance. Pandas represent friendship and peace in Japan, and the "open house" style event allowing unrestricted viewing is rare. Moreover, Japan has a culture that appreciates orderly lines and queues, showing patience and respect towards others.

In the US or EU, zoos also hold special events targeted at specific popular animals. However, the intensity of the crowd response might be different due to differing cultural associations with these animals. The method of organizing the event might also differ based on local customs and attitudes towards orderly queuing.
