The name of the chocolate treat I purchased this time is “Black Thunder (ブラックサンダー)” which is produced and sold by “Yuraku (ユーラク)” and priced at 30 yen (about 0.3 USD).

Yuraku Black Thunder was first introduced into the market in 1994 and afterward became a big hit.

And today it is said that the manufacturer Yuraku sells over one hundred million Black Thunder bars in one year.

Yes, Yuraku Black Thunder has now become one of the most popular chocolate candies in Japan.

It is especially popular among young women, but I don’t know why.

The chocolate bar Black Thunder features its pleasant crunchy texture that comes from cocoa cookies embedded throughout the candy. The chocolate has a mild cocoa flavor and is not overly sweet.
