well I've heard few times that ramen could be salty (depends on prefecture cuisine & cook maybe?) but I don't think it's always the case.
I bought imported ramen from jp, vn, cn, thailand ... south asia, egg yolk one, rice noodles, instant noodles, miso, kimchi ... those were interesting & different from local.
But I don't remember very salty ones. Spicy? Maybe. Maybe traditional recipe assume salt addition manually while boiling, by cook.
The tastyest noodle thingy I ate was beashbarmac from central asia.
