“Goukaku iyokan” means “five-sided iyokan” with “iyokan” being a certain type of orange-skinned citrus fruit. Someone at the Hizuchi Tachibana 4H Club in Japan's Ehime prefecture realized, however, that “goukaku iyokan” can also mean “to have a good feeling about passing” - same pronunciation, different spelling!
The fruit-shaping technique is similar to that used to create heart-shaped cucumbers, baby-shaped pears and square watermelons, being that a mould placed around each immature fruit compels said fruit to conform to the mould's dimensions. The oddball oranges show off their pentagonal profile best when sliced, which is a lot less disturbing than cleaving an already creepy baby-shaped pear.
Due to the special attention accorded to each and every prospective pentagonal orange throughout its lifetime on the tree, expect the cost per fruit to be higher than your average, run-of-the-mill round citrus. It matters not: concerned and caring parents will snap up these lucky oranges faster than an examination monitor can say “put down your pencils!”
