Yuraku make Black Thunder chocolate bars… and, with the exception of a few related collaborations, that seems to be about it. Since the product has been extraordinarily successful for them, though, I guess that’s fair enough. This is a variation of the usual Black Thunder. It features the usual combination of rice crisps and dark cocoa biscuit covered in chocolate, but the chocolate is lighter in colour and flavoured with kinako, roasted soybean flour that is quite popular in sweets here, especially winter ones. The result is a bit of an unusual flavour and less sweet than usual, but still nice enough and worth a try.
