I found Kokura a bit of a suprise packet. Instead of just finding Mandarake by itself (as most are), there are numerous anime and gaming related stores together in one multiple level building. There is Mandarake, Jungle and Robot+Robot just to name a few.

Ill post some pics with the map of the building and some pics of the cabinets in Mandarake and Jungle. To be honest, I really found this place to have more varied items compared to other stores in Osaka and Hiroshima.

Also in Nagoya at the moment and been finding this place alright too which when ready, I will give Heroic Decepticon locations and details of the shops I have found in other places than his guide shows.
