What to pack in India for Japan

Round pins from India need a Type A adapter in Japan.

Round pins: a plug adapter to Type A. Source: Bureau of Indian Standards.
Each device from India: read INPUT. 100-240V covers Japan's 100V; 230V alone needs a voltage converter (JNTO).
India: 50Hz. Tokyo: 50Hz. Osaka: 60Hz. A 50/60Hz label covers all three.

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