The plug used in Japan.
Eastern Japan (including Tokyo, Yokohama, and northern regions) operates on 50Hz frequency, while western Japan (Osaka, Kyoto, Hiroshima, and southern areas) uses 60Hz. The dividing line roughly follows the Fuji River and Itoigawa-Shizuoka geological fault. Most hotels and public spaces use standard Type A outlets, though some newer buildings include Type B grounded outlets for safety.
