Both Karabom and Charabom is correct spelling. I believe that Karabom is more the Japanese (and more correct) spelling, because it actually makes sense. Where as Charabom has the "ch" sound that would be awkward in Japanese.
True, i always pernounced it karabom, but i think ch is a proper romanization for japanese letters, they're are several of them, and some of them like this one don't make since.
