Maboroshi-ken (まぼろし軒) is a popular ramen shop in Tokorozawa. This dish is my favorite Tonkotsu-Shio Ramen (とんこつ塩ラーメン), which is ramen with broth made from pork bones and salt. Just the thing to fill your stomach after a long afternoon walk.
Maboroshi-ken just started their lunch hour. Until recently they were only open at night.
I don't know about everywhere else but in Japan there is a thing called Shime (締め pronounced She-meh). When people go out to eat and/or drink in Japan (which we call Nomikai (飲み会)) it can lead to a second stage which we call Nijikai (second party) where we all go karaoke, bowling, or just to another Izakaya. The bigger the event, the longer these after parties keep on going.
Anyways, the Shime comes at the very end of the night (i.e. early morning). And this is just speaking from experience but a lot of times this ends up being ramen, probably because ramen shops tend to be open in the middle of the night and you can be in and out of the shop quite quickly.
Eating ramen at 4am is probably not the greatest idea health-wise. But it's still very very tasty!
Maboroshi-ken is open everyday from 11:30am to 5pm and again from 5:30pm to 4am.
