So eventhough the differences in voltages are not much, they still require different types of sockets. Also the sockets vary based upon the connection types, grounding preferences of a country. The result - LOT of varieties of sockets.
This silly location (Japan) splits itself between 50Mhz in the northern half of the country, and 60Mhz in the south! Tokyo uses 50 cycles while Osaka uses 60.

Thanks for that! Another bit of delightful trivia to cram in. I love to learn these little bits of 'life' that we normally just take for granted. Now, if only I could get on a quiz game show...
