Really? 100V? Sure, 50Hz is found all over the place - but usually at 230V. Japan is a WEIRD place, for historical reasons. Half the island is 60 Hz the other half is 50 Hz. So, they have two totally separate electrical grids! This led to some of the crazy problems at the Fukushima

As Gene already mentioned, why are you looking for a transformer at all? The split in split phase means that you can connect loads between either hot and the neutral to get half of the overall voltage. So if you have 240V line-to-line, you will get 120V line-to-neutral. I can think of two
