Hello,
I once got a japanese SEGA Megadrive when young. The alimentation bloc had two flat plugs (like americans) instead of our french two round ones, but the importator gave a small plug adaptor. So I believe you'll need to procure a set of worldwide adaptors (easy to find and not expensive) before going there.
But on the alimentation bloc I had a 110 / 220V switch, so I can't tell if they are still in entire 110V or if they have some areas in 220V.
So you'll need further info about voltage.
