Popo Sandwich is a takeout sandwich shop in Tokyo that sells fruit sandwiches and katsu sandwiches. Its fruit sandwich contains orange and pineapple, and it also offers donkatsu, chicken cutlet, and tamago sandwiches on soft, moist white bread. It has been in business since 1973 and opens at 7:30 a.m., so customers can eat in the small park next door. Around 1 p.m. stock runs low and the sandwich selection is limited.
