@Elan_Morin:
Not necessarily…..we are talking about a different culture here.....while here in the states, money may be top for most companies, that wouldn't necessarily be the case in japan, and in fact, I am pretty confident the dubbed openings issue isn't a money issue.
I know that it's probably not a money issue, but most companies, regardless of culture, are a bit more lenient to certain complications when they see a lot of zeros.
