This was when the refrigerator was new. It didn't stay like this for long. Trust me.
In Japan, our refrigerator was quite small. Our first one was dorm-size-ish. Our second and third ones was about what you'd expect in a tiny New York studio apartment with a compact kitchen or a dwelling designed specifically for the needs of a single individual who rarely cooked. They were small. Since coming to the U.S., I've had access to enormous refrigerators with large freezers and somewhat smaller ones and it has always been the case that I fill the available space.
Part of the reason that the bigger fridge isn't big enough in the U.S. is that the food is sold in bigger portions. Part of it is also that, the more I have, the more I'll take. I don't miss my tiny refrigerator in Tokyo, especially because I cook all of my own meals and do need a lot of food on hand, but I have been surprised that bigger appliances didn't really solve my problem. The food just grew to fit.
