I studied abroad with IES Abroad Nagoya in the Spring of 2019.
The IES abroad program at Nagoya is amazing. the staff for both the program and the university are very kind, and very helpful. they understand all of the struggles you might go through while studying abroad. Nazan also has counselors for international students.
Nagoya is a small but very nice city. In the areas where you will live, host family or dorm, there are very little foreigners so you don't have to worry about being treated like you know very little to no Japanese. it's also a very convenient city to make trips from. There are a lot subways, trains, and bus lines in the area to go almost anywhere of interest. And you can easily take the bullet train along the eastern coast which goes all the up to Hakodate and all the way down to Kagoshima. The airport is also a major one so you can easily take a domestic flight to a lot of cities.
The trips you are broad on are amazing as well and super generous. You get to go to some really cool locations, stay at very nice hotels and Ryokans (Japanese inn), and eat very good food.
The convenience and cheapness of the public transport system in Japan really encourages you to explore. I've made many solo trips. If your Japanese level is good enough, you can go almost anywhere.
Overall, this program completely change me. I was able to grow a lot as a person, a student, and a professional. My Japanese ability also skyrocketed.
I highly recommend this program for anyone who has the chance.
