The Instant Ramen Museum is run by Nissin, the company that invented both the instant noodle, and the cup noodle. A short distance from Osaka, the museum details the history of the invention of instant noodles, and also has a wall display of all Nissin noodles ever sold (in Japan).
There is a replica of the place where the first Chicken ramen was conceived, and exhibits showing the various inventions that were needed to make instant noodles a reality. A nice CG video shows the continuous production system (no wax coating involved, sorry HK rumor mill).
There are workshops you can join (booking needed) where you learn to make fresh instant noodles from scratch, the less organised (like us) can design and package their own cup noodles. There seemed to be some ingredients there that were not available in normal cup noodles.
And of course the cafeteria is a line of cup noodle machines where you can buy region limited Nissin noodle products or even tiny JAL cup noodles.
