I am not quite back in Tokyo, yet I quiver when I think of the Densuke watermelons. The more than 1200 varieties of watermelon range in weight from less than one to more than 200 pounds; the flesh can be red, orange, yellow or white.

Densuke watermelons, a type of black watermelon grown only on the northern Japanese island of Hokkaido, are often medium-sized and due to their rarity are given as gifts.

There were only sixty-five of the fruits among the first harvest last season. They are harder and crisper then most watermelons yet they have a different level of sweetness. As the most expensive watermelon ever sold in Japan, it is likely also the world’s most expensive watermelon except for muskmelons.
