Yes, japan is split into a 60 Hz (west) and a 50 Hz (east) power distribution systems. They do have four main frequency converter stations that can move power between the two networks, three of them are shown on this power distribution map: https://en.wikipedia.org/wiki/Shin_Shinano#/media/File:Power_Grid_of_Japan_as_of_2008.png https://en.wikipedia.org/wiki/Shin_Shinano#/media/File:Power... Taken together they have a capacity of around one Gigawatt. Here is some more information on the used technology: https://en.wikipedia.org/wiki/Higashi-Shimizu_Frequency_Converter https://en.wikipedia.org/wiki/Higashi-Shimizu_Frequency_Conv... https://en.wikipedia.org/wiki/Sakuma_Dam#HVDC_frequency_converter https://en.wikipedia.org/wiki/Sakuma_Dam#HVDC_frequency_conv...
