Opponents of this change believe that it is unrealistic to expect any change to come to current provincial boundaries, and hence prefectures are here to stay, at least in the short term. Moreover, they claim that the sheer size of provinces (which, according to them, do not need to be shrunk) means that prefectures are needed as an intermediary level. Finally, they defend the establishment of prefecture-level cities by arguing that it helps in encouraging urbanization, and cooperative development of entire regions.
