The school trip, or "ensoku," is an essential part of Japanese education.  This picture depicts an elementary school trip to Ueno Park in Tokyo on a Saturday in October.  As can be seen, the children all wear the same uniform, and walk in pairs.  Many scholars of education look at the school trip as an important part of socializing Japanese children.  The children in the photo are probably local children on a day trip. However, older children throughout Japan, once during junior high school and once during senior high school, go on overnight trips with multiple educational goals.  Destinations for these trips vary from Tokyo Disneyland to Hiroshima.
