Late at night while traveling in Japan, when you’re alone in a dark alley and spot the light from a convenience store, you can’t help but feel a sense of relief. But have you noticed something interesting? No matter the brand, there’s always a magazine rack or an eat-in area right next to the glass window.
At first, I thought it was just about seating arrangements, but when I asked my Japanese friend, I found out that wasn’t the case.
