The system in the PC universe is called Aichinatokawa currently. It is located 'next door' on the same Galactic plane as HUB-K-137 Pleasantville. If one finds that, then one can spin about and find Aichinatokawa.
If one also finds HUB-G-138 Diversica, then aligns Pleasantville so that it is to the right of Diversica, the red star just 'behind' Pleasantville is where Aichinatokawa is located.
