Where your plug will also work
All countries →These countries use at least one of the same socket types as Japan, so an adapter bought for this trip often works there too.
What to expect in Japan
Type A at 100 V, ungrounded, with Type B in some newer buildings. The voltage is the lowest in the developed world, and the country runs 50 Hz in the east and 60 Hz in the west. North American plugs fit; everyone else needs an adapter.
What the sockets look like
Power in Japan
Japan, an island nation in East Asia, is known for its advanced and reliable power infrastructure. Japan uses Type A and Type B power plugs. The supply is 100 V, at 50 Hz in eastern Japan and 60 Hz in the west. Japan's power generation relies heavily on natural gas, coal, and nuclear energy, with a growing emphasis on renewables like solar and wind. The national grid is highly reliable, with minimal outages and robust disaster-resilient systems, especially after lessons learned from the 2011 Fukushima incident. Overall, Japan's power infrastructure is a testament to its technological sophistication and commitment to energy security.
