7-Eleven Hawaii is adding a Japanese-style egg salad sandwich to its menu statewide, a small win for shoppers who like Japanese convenience store food.

• The sandwich is creamy egg salad on soft, fluffy white bread, modeled on Japan's popular tamago sando.
• It is made locally rather than imported.
• Oahu shoppers pay a bit less than people on Kauai, Maui and the Big Island.
• It goes on sale in stores across the state starting tomorrow.

Outlook: If it sells well, expect more Japan-inspired items to show up on local convenience store shelves.
