Only In Japan?

Would you like to have a taste of a banana that costs 600 Yen "each"?  This banana, branded Penguin Banana, is available only in Japan (currently) and selling reasonably well in Osaka at 600 Yen each.    Someone who has eaten it said that it is not only sweet and rich in taste, however the after taste is not heavy or filling, in fact rather refreshingly fruity.

The taste is special because this banana matured very slowly, which requires twice longer the time needed for an ordinary banana.   It is also specifically grown and nurtured in such a way that you can only collect one or two of such a banana for every single tree.

The fact that this banana is selling quite well at such a price shows 

a new trend of fruit consumption in Japan.    Research also showed that overall banana market in Japan is the least effected by changes in the economy at present.   

I personally find it hard to believe that one 

would spend 600 Yen on a banana instead of a dessert set, say a standard strawberry cream cake with a cup of coffee, which you can get for the same price here ...
