You're misunderstanding something here, Japan sells normal reasonably priced fruits and special premium fruits that had lots of extra work was put in to them (For example cutting most fruits off plant so more nutrients go to the remaining ones). The premium ones can't be mass produced and takes more time and effort to produce thus are inevitably expensive. We hear more about the latter outside of Japan as they're a novelty to us (and they're an item marketed at tourists).
Also just to be clear 'premium' in this context is not the same as 'organic', it's "above" that.
