Japan has again shown off one of its greatest innovations - square watermelons.

Where do we get them? Our little ("compact") apartment refrigerator has never seen an entire watermelon, and I'm afraid it would probably have a compressor attack if it did. Over the years I've become expert at buying and arranging almost everything I need it to work with, but, until now, watermelons were just not a consideration. At the prices in Japan however, it's a wonder any watermelon was a consideration for anyone, even when they only came round! Fifty dollars for a watermelon?

Each melon sells for 10,000 yen, equivalent to about $83. It is almost double, or even triple, that of a normal watermelon.
