Japan voltage vs Malaysia: plug adapter and voltage compared

Japan runs on 100V and Malaysia on 230V. Tourism Malaysia says a standard 3-pin plug is commonly used, and Singapore's Consumer Product Safety Office lists Malaysia among the countries that use Singapore's plug type, three rectangular pins. Japan's outlets take Type A plugs with two flat pins (JNTO), so bring a plug adapter to Type A.

What to pack in Malaysia for Japan

Three rectangular pins from Malaysia need a Type A adapter in Japan.

Three rectangular pins: a plug adapter to Type A. Source: Tourism Malaysia, and the Consumer Product Safety Office of Singapore.
Each device from Malaysia: read INPUT. 100-240V covers Japan's 100V; 230V alone needs a voltage converter (JNTO).
Malaysia: 50Hz. Tokyo: 50Hz. Osaka: 60Hz. A 50/60Hz label covers all three.

Why Malaysia is grouped with three rectangular pins: The Consumer Product Safety Office (Enterprise Singapore) writes “Some countries that use the same type of mains plugs as Singapore include Brunei, Hong Kong, Malaysia or the UK.”.

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