We are staying at the Toyoko Inn here in Busan. It's a Japanese chain of hotels. There are a fair amount of businesses catering to the Japanese here, I'm guessing lots of Japanese come here for business with this being such a big port and industrial area. There is actually a ferry to Japan right down the street from our hotel.
As I had hoped, its just like the hotel I stayed at in Tokyo. The prefabricated bathroom pod, the small quarters, and complimentary pajamas:) There is a free "Japanese breakfast" tomorrow morning, I can't wait!
