These days--with the rise of deputy services, 
international PayPal, increased acceptance of 
IPMO's, and online translators that render 
Japanese into text that can at least be vaguely 
understood by non-Japanese speaking people--there 
are more Westerners than ever before bidding on 
YJ and buying directly from Japanese dealers.  
It's natural that some Japanese collectors resent 
this increased competition for an ever-dwindling 
amount of cels, as prices skyrocket higher and 
higher and more cels leave their home country 
forever.  

I can certainly relate to that feeling, though.  
Aside from cels, I also collect old original 
blues and rock records...  specializing in the 
rare music of my home state, Texas.  When I first 
started collecting, I could stop by just about 
any local thrift store or garage sale, and walk 
away with a some rare prizes for just a few 
bucks.  Nowadays, there's very little to be found 
here locally.  The well's gone dry.  And most 
infuriating, many of the local records I want 
most are now in the hands of collectors overseas, 
France and Sweden mainly, with soul-crushing 
$500 - 1000+ price tags.  I know it's petty of 
me, but I resent these foreign collectors driving 
up the prices of the music I love, the music that 
is my heritage.  I almost feel as though the 
local culture and history has been ransacked and 
sold overseas to people who cannot possibly 
appreciate it the way I do.

Anyhow, a year or two ago, when I decided to sell 
off part of my record collection on ebay, I put 
in big bold screaming letters in my 
auctions "WILL NOT SHIP OVERSEAS!!! U.S. BIDDERS 
ONLY!!"  Did it matter?  Nope, they bid anyway.  
And they bid so crazily high that I would have 
been a fool to turn down that kind of money.  My 
valiant efforts to singularly turn the tide 
against foreign buyers and rising prices ended 
with my giving up and giving in to greed.  Alas.  
But really, it was a LOT of money! ^_^  

So, I can totally understand why some Japanese 
collectors have drawn a line in the sand and 
refuse to sell overseas.  Fortunately for us, 
those kind of people are in the minority, and 
probably always will be.  In the end, money talks 
(even if it does talk in a cryptic Babelfish auto-
translation.)
