The secret to Japanese model is , all regions are equally developed so people don't migrate and over crowd main city like Lahore or Karachi
Load is distributed across all country not just 1-2 city
They love to live in their own zone and cities which have jobs , schools , hospitals and water
Pakistan can be divided into 90 Provinces with 1-2 main cities in each province
Similar to Japanese model
Japan as I said before has 47 regions , and it is half as big as Pakistan
Pakistan can easily be divided into 97 zones
Each city gets it's own budget
We need to forget concept of 4-5 provinces and adopt the Japanese style small zones

Each city can be allocated a zone of 100 miles
Each city gets budget allocation (Confirmed budget + Bonus budget from Income tax paid from citizen of city)
