I have learned many interesting things (even in the short time I have stayed with my host family) that I will hopefully eventually blog about, but I did say I would write an entry about Japanese style baths first, so here goes.
On the first night I arrived at my host family I was asked if I wanted to take a bath. Actually, strictly speaking I was asked "おふろに入る?" or ohuro ni hairu? In class we have been using ohuro as a term that means "to bathe or shower", so as the American that I am I interpreted this to mean, "Do you want to take a shower?". At this point I was so frazzled by trying to figure out the words they were saying that I was willing to say yes as soon as I knew what I was agreeing to. As I entered the bathroom I realized that they didn't actually have a shower and that the bathtub was filled with water. The homestay director had told all of the homestay students that we would probably be offered this, and if we wanted to take showers instead we would have to work it out with our host family.

Japanese Style Bathtub in my Family's Home
The reason that I was offered to take a bath first, even before my host father, is because as the guest I receive special privileges in the house. During breakfast my host mother serves both my host father and I before eating anything herself. Both of my host parents want to make sure that all of my needs are met and that they are attentive to me as a guest in their home. By letting me take a bath first the are giving me the privilege of using the cleanest and purest water, as well as giving me the honor of being the first in line, so to speak.
There are many rules of etiquette in Japan, most of which I do not completely understand. Being at my homestay has taught me that although I have already learned a lot about Japanese culture, there is no way that I am anywhere close to being able to even close to fully understand Japanese society. So much about how I view the world has been socialized into me as an American, and I cannot take away that prejudice, no matter what I do. The most I can do is be aware of it and attempt to compensate.
Here is a wikipedia article describing Japanese Etiquette.

On a side note, here are the grandkids of my host parents. The one flashing me the peace sign is Ai and her twin sister is Yuu. They are both four years old and completely adorable.
