    Electricity wide effectively the country is split in two. As a result of historical reasons,

    Eastern Japan (including Tokyo, Kawasaki, Sapporo, Yokohama, and Sendai) runs at 50 Hz; Western Japan (including Okinawa, Osaka, Kyoto, Kobe, Nagoya, Hiroshima) runs at 60 Hz. This originates from the first purchases of generators from AEG for Tokyo in 1895 and from General Electric for Osaka in 1896.[3][4]
    This caused a problem during the earthquake, as Western Japan had a surplus of power but the interchanges(where the frequencies are converted) are limited and cannot handle the full load.
    They can only transmit 1GW through these converters. They are currently working on improving the throughput of these converter stations, but it still not be sufficient to allow power transmission to the whole country.

    It will highly unlikely that Japan will ever to one system as the politics and the costs would be prohibitive.
