They are one of the largest ISPs in Japan and Japan (at least certain  
parts, like Tokyo and Osaka) is _significantly_ more advanced in  
terms of broadband penetration than the US.

This is, of course, why IPv6 has the traction it has.  I used to be  
much more sanguine about IPv4 address space availability.  That was  
long ago.  Given growth patterns, the only way IPv4 will continue to  
be usable is by the use of NAT.  For various reasons (some good, some  
not), NAT is seen as the spawn of the Devil.  As such, IPv4 with more  
bits becomes less non-attractive.

Well, there has been a flurry of /8s being allocated by the IANA to  
the RIRs which are announced to the various operational mailing  
lists.  I think it safe to assume those /8 allocations are not being  
done to redistribute the remaining free pool to the RIRs...
