This is スタミナ (stamina) ramen. What does "stamina" mean when applied to ramen? It means every topping they have. A couple kinds of seaweed, sprouts, corn, pork, onions, and butter is what I recall off the top of my head. Butter and corn pair very well with miso ramen. For about 3 bites. Then it's just too rich.
A few months ago, before I moved out of my old residence in Ogikubo, a 味噌一 (Misoichi) opened a couple minutes away. There are a few locations in the western part of Tokyo, check the map on their website. The Ogikubo one is about a 15 minute walk from the station. The one in Koenji looks like it's right next to the station. Go to the one in Koenji. Koenji is fun. Ogikubo isn't.
It's a great shop, the standard bowl is full of vegetables, no pork. It's nice, it gives you the impression that you are eating healthy. I'm talking about the standard bowl, not the スタミナ one. The stamina bowl just hurts.
