I have many Japanese CDs including Blue Note. CDs in Japan cost in the area of US$18-$25 each, so although you're paying a premium in US terms you're actually paying the standard Japanese price. I have, however, seen mini-LP japanese CDs selling for as much as $34 in the US but generally they go for less. Most of my Japanese CDs were purchased directly from Japan. I first started doing this because some titles (mostly jazz) were only available in Japan. It seems that Japanese consumers had more choice in American jazz than we in the US had, maybe they were bigger fans. At least there must have been a better market for US jazz.
As far as sound quality, many Japanese CDs are superior in sound quality but there is no guarantee. Certainly the question needs to be considered about the value of the additional $10-$20 in cost. The additional cost is easier to handle if there is no other choice to purchase a title.
PS: Japanese manufactured DCC and MFSL CD titles are also going for a premium over the same US manufacured titles.
