Ramen is a popular comfort food in Japan because, unlike many Japanese foods, there’s very little formality in eating it, it’s not especially good for you and therefore tastes wonderful, and you’re generally free to customize to your heart’s content, choosing a broth of your liking and then heaping on the toppings until you can barely see the noodles if you so desire.
Spicy ramen varieties aren’t uncommon, either, with many popular chains such as Ichiran offering customizable spiciness levels from one to ten. Of course, if you’re the right combination of bored, crazy and rich, you can pay extra to exceed the tenth level of spiciness; right on up to 200 times normal.
