Ichigo Kiss!

Yes yes! One of the few lovely things you get during winter is...........

As written on the wrapping(for those who can read Japanese), this type of strawberries is called Tochi Otome.

とちおとめ [3]
「とよのか」と「女峰」を交配し、さらに「栃の峰」を掛け合わせ、栃木県農業試験場によって育成された品種。品種登録は1996年。女峰より粒が大きく甘さも強い、日持ちが良い品種。従来の二大勢力であった「とよのか」や「女峰」に代わり、本記事の執筆版現在、日本一の生産量を誇る。

Tochi Otome
A Strawberry breed raised at the Tochigi Prefecture Agriculture Test Centre by crossbreeding the Toyonoka breed and Nyohou breed, and interbreeding with the Tochi No Mine breed. The breed was first recorded in the year 1996. This good breed has fruits bigger and sweeter than the Nyoho and lasts longer. In place of the two monopolizing breed, Toyonoka and Nyoho in the past, as of this article's writing now, it is now famous as Japan's number one strawberry produce.

The one I bought isn't that sweet, but still quite nice. Well, it isn't the peak season yet anyways. It should be really tasty towards the end of winter and beginning of spring.

And did you know?

甘みがあるため果物として位置づけられることが多いが、草本性の植物であるので正確には野菜に分類される。

Because the strawberry is sweet, it is usually placed as a fruit. However, as a plant having herbal properties, in accurate terms, it is classified as a vegetable.
