I had a Japanese teacher a few years ago who explained that Japan's ramen is the US's "burger and fries". It's calorie-rich processed food that's available everywhere. They are prepared in advance, served very quickly (usually within a few minutes), and people finish their meals within 15 minutes. It's far closer to "fast food" than most Westerners realize. The average ramen outside Japan is far more elevated than within Japan.
