Potama Makishi Ichiba Ten is a breakfast stall inside Makishi Ichiba in Naha, Okinawa, selling pork tamago musubi. Hot rice is filled with Spam and egg, then topped with ingredients such as mentaiko mayo, sea grapes, and mozuku tempura. Seven groups have waited before the 7 a.m. opening, and a seating area across from the stall can be used on rainy days. Orders are taken one group at a time, so waits run long.
