The first overnight school trip in elementary school

My youngest child, who is in fifth grade in Japanese elementary school, just got back from an overnight school trip. Each year the fifth grade students travel to a location within Saitama Prefecture, for a trip of a lifetime. The trip is not just about independence, but also exposing students to experiences they may not otherwise have. Such as climbing a mountain, orienteering, camp fire and / or bonfire. Thankfully my little ones have plenty of experiences of each. But for some children it is their very first time to experience the great outdoors in this way. 

My oldest two children actually didn't get have to get this experience because of the pandemic. Likewise, my youngest missed out on an overnight stay in preschool. My four children went to a preschool that had an overnight stay in the kindergarten gymnasium in their final year. However, my forth child was denied the experience due to the pandemic. Because both the preschool and elementary schools didn't have overnight events for three years in a row, out of concerns about virus spread, between 2020 and 2023. 

My youngest has stayed in friend's houses several times, so it wasn't her first time to stay outside the house without us. But because she missed the kindy night, it was her first time to stay overnight for a school related trip. She's very tired right now, but I can tell she really enjoyed it. I also sense that she's found a little more of herself thanks to the experience. I think it is fantastic and valuable opportunity for children. It is also a good prelude to the big trip in 6th grade, where children go further afield for two nights and three days.

Have you heard of these type of stays before? Did your children or students get to do an overnight stay in 5th grade?
