There are basically two approaches to multiresidence buildings in Japan. There are "mansions": large, modern and built to last, normally all concrete and having a single common entrance, and then there are "apaato": usually 2-3 stories, separate entrances, typically wooden, and ramshackle after 10-15 years.
