Map of Japan's electricity transmission network, showing differing systems between regions. Electricity transmission in Japan is unusual because the country is divided for historical reasons into two regions each running at a different mains frequency. [10] Eastern Japan has 50 Hz networks while western Japan has 60 Hz networks.

The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.
Today most 60 Hz systems deliver nominal 120/240 V, and most 50 Hz nominally 230 V. The significant exceptions are in Brazil, which has a synchronized 60 Hz grid with both 127 V and 220 V as standard voltages in different regions, [20] and Japan, which has two frequencies: 50 Hz for East Japan and 60 Hz for West Japan.
Location of Higashi-Shimizu and Japan's two utility frequencies Schematic of Higashi-Shimizu Frequency Converter. Higashi-Shimizu Frequency Converter (東清水変電所, Higashi-Shimizu Hendensho) is the third facility in Japan for interconnecting the power grid of eastern Japan, which operates at 50 hertz, and that of western Japan, which operates at 60 hertz.
This map reflects the nominal voltage of residential buildings of most countries. In the USA and Canada, there are 2 nominal voltages: 120V and 240V concurrently. This is not a 3 phase system and 240V is not a phase-phase voltage. This system is unique and is only used in certain parts of the world. 230/380V in Europe does not use a similar system.
Description: Deutsch: Weltkarte mit Darstellung der Nutzung von Bildwiederholraten bei HDTV. Die benötigten Daten stammen hauptsächlich aus w:hdtv und . Bei europäischen Staaten wurde die Empfehlung des EBUs genutzt und mit die Spezifikation des HD ready-Labels berücksichtigt, dessen Geräte zusätzlich zum traditionellen 50Hz auch 60Hz-Signale annehmen und wiedergeben muss.
Japan has 50 Hz and 60 Hz networks. Continental North America, while operating at 60 Hz throughout, is divided into regions which are unsynchronized: East, West, Texas, Quebec, and Alaska. Brazil and Paraguay, which share the enormous Itaipu Dam hydroelectric plant, operate on 60 Hz and 50 Hz respectively. However, HVDC systems make it possible ...
