Black Thunder

You can get Black Thunder almost everywhere at convenience store.

Their advertising slogan is:Delicious lightning class
Looks like chocolate bar, contains cookies.
So this is more like American sweet level than average Japanese snacks.

This is cheep (you can get 3 for $1) but tastes so good.
I bought it all the time when I was a college kid.
Especially before and during exam season.

One time, famous Japanese gymnast Kōhei Uchimura who is Olympic gold medalist said:
“I love the Black thunder, I eat this all the time. During waiting my performance as well.”
at his interview.

From the next day, it’s gone from every single convenience store for few weeks.
(Japanese Version of Wikipedia mentioned about Black Thunder)

Where is my Black Thunder~!!!!
At that time I was very mad at him 😉

Anyway, it’s really good and cheap snack.
