study camp; overnight field trip; traveling class
A school trip where students stay overnight, often for nature study or skiing. Common in Japanese elementary and junior high schools.
Next month, the fifth graders will go on an overnight field trip to Nikkō.
We handed out the guidebook for the study camp.
class held in a different room
Refers to moving to a specialized classroom (e.g., music, science, art) instead of staying in the homeroom. Common in school contexts.
Music class is held in a different room, so we go to the next building.
When you have a class in a different room, please be careful not to forget anything.
