I wasn't aware Epson had regionalized their chips, as apparently, HP
has, as well. HP told me they were doing it "to control for gray market
and currency differences", but I suspect it may have more to do with EU
laws which will shortly require the cartridges to be refillable.
Is the differential that great with the larger cartridges? I hadn't
looked at that factor. Obviously, Epson being a Japanese company would
compete most heavily in their own country to maintain market share. Do
HP or Lexmark cartridges show the same differential in Japan? I wonder
about Canon ink cartridges.
The whole thing is pretty annoying. Could it be worthwhile to buy
larger ink cartridges in Japan and having them shipped, and then either
resetting or replacing and resetting the chips, if one wanted to stick
with Epson inks?

Differential is similar with the larger cartridges - ie 50% more in the
USA, double in UK.
The large cartridges are region chipped too.
It looks like the smaller epson cartridges, chips could be swapped over
fairly easily, then reset with a hardware resetter. The SSC service
utility doesn't work too well with recent epson printers. It now
monitors ink levels okay and can "freeze" them for people using CIS, but
can neither reset cartridges, nor reset the printers internal waste
counters.
It would be nice to know how to change the Epson printer region code
rather than the cartridges. I suspect that the coding is on a
replaceable ROM chip on the main board. Replacement ROM chips are
available, but getting hold of the right chip for the Japanese model may
not be so easy - and I don't even know if that would work.
Possibly to aid obfuscation, Epson name printers differently for
different markets, and supply different drivers. But, you can use the
Japanese windows XP driver for the "PX-G5000" for the R1800, it will
install in english, and even adds some features not on the R1800 driver.
AFAIK, it's not so easy to swap chips with the large cartridges. Some
people buy the 220ml carts and use them to feed CIS on smaller printers,
others use them to refill cartridges - but as I understand it, the ink
is packed in a plastic bag inside the cartridges, and successfully
refilling them isn't simple.
HP have region coding - to their credit price differentials are less
blatant - but OTOH the new inks are just outrageously expensive
everywhere. Perhaps they learned with the Design Jet 130 that a
reasonably economical printer didn't make them as much $$$!. They are
moving slowly but surely over to pigment inks for higher end amateur and
pro level photo printers - as is Canon.
I haven't looked at Canon price differentials. I'd expect that they may
be similar to Epson.
