What are the positives and negatives of the Japanese home?

Answer 1

An unusual feature of Japanese housing is that houses are presumed to have a limited lifespan, and are generally torn down and rebuilt after a few decades, generally twenty years for wooden buildings and thirty years for concrete buildings

aditional Japanese housing does not have a designated use for each room aside from the entrance area (genkan, 玄関), kitchen, bathroom, and toilet. Any room can be a living room, dining room, study, or bedroom. This is possible because all the necessary furniture is portable
