Teaching English
Offered the option by an administrator at my university, I hopped on a bus and taught at an English camp in the rural Gunma Prefecture for a weekend.
It was fun to interact, teach and eat with high school kids, most of whom did not speak English well but were required to only do so this weekend. I was chosen, among others, specifically because our Japanese wasn’t particularly strong. It was tough and frustrating for some of the kids but certainly got the point across.
Secretly, during breaks, I did use it as an opportunity to push my Japanese.
We bonded some and laughed a lot. Like others, I led specific lessons and groups of 10 or so rotated through this massive lodge-like space, atop a peak amid a massive, wilderness of fall colors around us.
Like any culture, they were teenagers feeling out what kind of people they are, and we were slightly older young adults, who happened to also be foreign and American, so there was an awe. This was one of the simpler, yet more transformative and likely memorable experiences.
