This week while I was at my other school, my usual school had their 'school camps' where each grade went off and did something cool for 3 days. Third years do a trip to Kyoto & Nara and learn some history and the first years go to a camp ground facility in Gotemba.
I voluntarily came to visit the first years after work one night just to see them do a bonfire thingy. Was pretty unique out in the forest and wildlife and Japanese stuff to boot.
