This autumn sees the shelves of convenience stores throughout Japan groaning under the weight of a bumper harvest of new flavor sensations. Here's our round-up of this year's crop:

Pumpkin is of course a classic autumnal flavor and true to form, this year Nestle has released a limited edition pumpkin-flavored Kit Kat for Halloween. Häagen-Dazs, too, has jumped aboard the pumpkin bandwagon by releasing pumpkin-flavored ice cream earlier this month along with a murasaki imo (purple potato) flavor. Purple potato has also popped up in Kinoko no Yama’s roster of seasonal flavors this year, along with maple and roasted chestnut.

According to Mainichi, crunchy Japanese pears (nashi), as opposed to the differently shaped and softer-textured European pears, are quite literally the flavor of the autumn months this year. Last month Japanese pear-flavored Fanta went on sale for a limited time only and beverage maker JT also brought out a pear juice with a pulpy texture that’s distinctive to the Japanese pear. In addition, Gari-Gari Kun’s pear-flavored ice pops have also proved so popular since their initial release in 2010 that this year they’re being sold in packs of seven.

As surely as the trees will soon be bare of leaves, many of the limited-edition items mentioned about will be sold out by the end of autumn, so those who don't want to miss out on these novel nibbles and drinks ought to hurry.
