Nestle Japan will open its first stand-alone Kit Kat Chocolatory store in Tokyo’s Ginza district on February 2 – and marking the occasion with gifts of special sushi Kit Kats.

Since the first Kit Kat Chocolatory opened in January 2014 as a specialty store offering premium and exclusive Kit Kats, the franchise has expanded to eight outlets across Japan, all within major department stores.

For the grand opening of its stand-alone store, the company has created a set of three Kit Kats shaped like sushi – a combination of Kit Kats and rice puffs coated with white couverture chocolate. The maguro (tuna) version is topped with a raspberry-flavoured Kit Kat, the uni (sea urchin) version is made with a Kit Kat with the flavour of Hokkaido melon with mascarpone cheese, while the tamago (egg) version features a pumpkin pudding flavoured Kit Kat.

Actually, the idea of a sushi Kit Kat was shared on social media by Nestle Japan as an April Fool’s Day joke last year, but the response was so huge the company decided to make it a reality. There will be 500 sets of the three sushi Kit Kats, with a limited number being offered each day to customers spending more than 3000 yen (US$26.50) or more at the new Ginza store.

There are also plans to open a cafe on the second floor of the store in the next several months where customers will be able to try special items such as baked madeleines made with Kit Kats, or even make their own Kit Kat creations using toppings of their choice.
