From the Yuraku Confectionery "Black Thunder" series, "White Black Thunder on a business trip to Okinawa" has appeared. It will be released on June 5th in advance of "Department Store Ryubo" in Naha City, and on June 15th at some stores such as airports in Okinawa Prefecture. It comes in 12 bags and costs 918 yen (tax included).

This is an Okinawa business trip version of "White Black Thunder," which is a popular souvenir from Hokkaido. When traveling to Okinawa, it was newly developed with a formulation that is particular about Okinawan ingredients.

"Chatan salt" made from 100% seawater from Okinawa is added to the cover chocolate. In addition, almonds whose surface is coated with brown sugar from Okinawa Prefecture are added to the center part. It's finished in a slightly different black thunder.
