No.1 Souvenir at Toyohashi Station. Over 5 Million Sold: 'Black Thunder Anmaki' Becomes Toyohashi's New Standard Gift

Okame-do Co., Ltd. (Toyohashi City, President: Takahiko Mori), a confectionery maker with over 70 years of history in the East Mikawa region of Aichi Prefecture, announced that its collaboration product with Yuraku Confectionery's popular 'Black Thunder' chocolate, 'Black Thunder Anmaki,' has secured the number one spot in Toyohashi Station's souvenir popularity ranking as of February 2026, according to JR Tokai.

'Black Thunder Anmaki' is a new-concept snack that harmonizes the crunchy texture of Black Thunder with the chewy texture of traditional Japanese confection wrappers. Since its launch in 2017, the surprising combination and textural contrast have become a hot topic on social media, leading to cumulative sales of over 5 million units.

### A Miraculous Collaboration Born from Challenge

The product was developed by the long-standing confectionery shop 'Okame-do' and Yuraku Confectionery to invigorate Toyohashi City, the home of Black Thunder's main factory. After repeated trial and error to balance the distinct characteristics of Japanese and chocolate confections, the product was finalized. It has now established itself as a popular souvenir at Toyohashi Station, and fans enjoy the added dimension of lightly toasting it in a toaster oven for an enhanced texture.
