In Japan, the standard voltage is 100 volts, and the frequency is 50 Hz in eastern Japan (including Tokyo, Yokohama, and Sapporo) and 60 Hz in western Japan (including Osaka, Kyoto, and Nagoya).
Most electrical outlets in Japan are Type A, which have two flat parallel pins. Some outlets may also accommodate Type B plugs, which have two flat parallel pins and a grounding pin. It's essential for travelers to bring a suitable adapter to ensure compatibility with Japanese outlets. Additionally, voltage converters may be necessary for devices that are not compatible with the Japanese voltage.
It's important to note that while many modern hotels and accommodations in Japan may provide universal outlets or adapters for guests, it's always wise to carry your own adapter and converter to be prepared for any situation.
