Those thousand-yen UPSes sound too cheap by a factor of ten at least.

I have a pair of APC ES 500 UPSes. The battery backup works OK in a 
yank-the-cable-out-of-the-wall test; I don't know about the surge 
protection. These units pass through mains power untouched until the 
voltage goes out-of-bounds (in which case it switches over to the 
battery), but a more advanced power-conditioned UPS should protect you 
against almost anything TEPCO can throw at you.

My desktop has too many disks at the moment so it draws more power than 
the UPS can supply - make sure you get one with enough capacity, and the 
beefier the UPS the more expensive it is.
