Japan’s major convenience store (Konbini) chain, FamilyMart, has announced its first-ever collaboration with “Sandwich Kobo Sandria,” a handmade sandwich specialist that enjoys immense support in Sapporo, Hokkaido. Starting Tuesday, April 21, 2026, five varieties from the “Proud Ham Sandwich” series will be released sequentially at stores across Japan.
The Soul Food of Sapporo! What is the 24-Hour Legend “Sandria”?
“Sandria” is a long-established sandwich specialty shop founded in 1978 in Sapporo, Hokkaido, with a history of over 40 years. Known as the first handmade sandwich shop in Sapporo to operate 24 hours a day, it is a true local “soul food” visited by many fans at all hours, from late night to early morning.
The storefront always features more than 40 varieties of voluminous sandwiches made with generous amounts of seasonal ingredients. From savory deli-style options to dessert sandwiches, its overwhelming variety and handmade warmth make it an iconic part of Sapporo’s food culture. Usually, one must travel to Sapporo to taste these famous sandwiches, but now they can be easily purchased at FamilyMart stores throughout Japan.

Recreating the Unstoppable No. 1! “Sandria-Supervised Ham Egg Sandwich”
The “Sandria-Supervised Ham Egg Sandwich” recreates the flavor of “Double Egg,” Sandria’s signature menu item that has boasted the No. 1 spot in popularity since the shop’s founding.

The highlight of this product is the egg salad, which emphasizes the texture and flavor of boiled eggs. A secret ingredient used is “Sanonto” (a rich Japanese soft brown sugar) along with black pepper. The deep sweetness of the Sanonto and the kick from the pepper create an exquisite balance, resulting in an addictive flavor that makes you want to eat it every day. A mayo sauce recreating Sandria’s special recipe further enhances the compatibility with the ham and green leaf lettuce.
