Any other laptop: read the adapter

The INPUT line on the power adapter decides it. 100-240V includes Japan's 100V.

How to read INPUT on a laptop power adapter: 100-240V includes Japan's 100V, 220-240V does not. 50/60Hz works in east and west Japan.

Japan's outlets take Type A plugs with two flat pins (JNTO). A laptop adapter with any other plug needs a plug adapter.
