A colleague of mine picked up some equipment in Tokyo a little over a year 
ago and did just this and ended up with a piece of equipment that did not
work about 6 months later.  The description of what had failed sounded like
a failed power supply.  You need to be careful when doing this.  If the
equipment is speced for 90-120 VAC, then there should not be any problem.
Unfortunately however much of the equipment for the Japanese market is
designed for only 100 VAC, 50/60 Hz.  For this equipment, unless you don't
mind the possibility of damaging the equipment, it is much better to just
spend the $15.00 or so for the step down transformer.
