Is Japan's voltage the same as Taiwan's? Voltage and plugs compared

No. Japan runs on 100V and Taiwan on 110V. Taoyuan City and Taitung County list Type A (two flat pins) and Type B for Taiwan, and the Talent Taiwan Office names the same two types. A flat two-pin plug fits Japan's Type A outlets with no adapter. A Type B plug, with its round earth pin, needs a socket with the third hole; Panasonic lists Type A and B for Japan.

Each device from Taiwan: read INPUT. Japan's 100V has to be inside the range.
Taiwan: 60Hz. Tokyo: 50Hz. Osaka: 60Hz. A 50/60Hz label covers all three.

Flow chart for travellers from Taiwan: does the plug have two flat pins, and does INPUT include 100V? If not, bring a plug adapter or a voltage converter.
