If you could do it all over again would you choose the same program?
I was on the Year-in-Japan program in the Spring of 2017 and it was a huge part of my college experience as well as why I came to Japan after college on the JET Program. The program is a great way to experience Japan, make Japanese friends, and learn Japanese while also connecting with many other students from all over the world.
For me, the homestay was my favorite part of the program. Living with a Japanese family was one of the most beneficial parts of the program. I was able to experience being part of a Japanese family firsthand and also was able to practice my Japanese 24/7.
Furthermore, the program's location is great. Being in Kobe, one can access all of Kansai easily and can also head to Tokyo or Hiroshima easily. The program itself plans several field trips which take people to some of these places such as Mount Koya and Hiroshima, but there is also plenty fo free time to explore the rest of Japan!
I strongly recommend that you check out this program.
