Like at Guilford, I had a choice when it came to housing. Here, the options are to either stay in a Seminar House or with a Japanese host family. As I've mentioned, I chose to stay with a host family. However, now that I've been here for a while, I see that both arrangements have their pros and cons.
If you live in the seminar house, you are placed into one of four buildings near the campus. It's about a half-an-hour walk. The trip isn't too bad honestly, and you can pay for a bus if necessary. Assuming everything works out right, you'll have yourself a roommate. Room's pretty big though, Ac/heater's better than any others I've seen here, and you get to sleep on a futon. There is a kitchen with plenty of equipment for cooking meals. You can come and go as you please, and there are no real restrictions.
If you choose to go for the home stay option, you are paired with a Japanese family and stay in their house for the semester. The family size vary greatly. One of my friends just has a hostmom. While another friend has six siblings to deal with. Additionally, travel times can be upwards of two hours. Also, many families have a evening curfew. However, your hostfamily takes care of both breakfast and dinner. You'll be able to practive Japanese on your family too.
Both options are great, you just need to know what you want. The Seminar House allows for more freedom, but you're on your own concerning food and other misc. The homestay program is great if you want to experience culture directly and really improve your Japanese communication.
