anime art or in other words rivalry japanese art is not considered notable in the western world. anime artists are not only disgraced, but also anime art's presence in respective artist's portfolio will lower their demand.
besides quality dubbing is entirely a different process, and requires a separate team. (as to some extent u also have to adjust facial expression meeting that areas specific connotative demands, using graphical renderation, etc )
since anime is oriential thing, whereas urdu n english are the widely spoken languages in Pakistan therefore it is really hard to dub japanese (which requires almost 8 years to get learnt) or any other oriental language.
besides, another aspect is "Imperialistic" approach cuz through these visual attributions are used by superpowers to form a colony in regions like Pakistan (geographically speaking Pakistan presence is really an important one to every superpower).
what u can see there is nickelodeon having a joint venture with ARY (i think), and can conjecture many things.
anime is not just big in far east. a japanese anime show, Grendizer (goldorak, goldtake in Europe and US) was extremely popular worldwide, dubbed in arabic it was probably the biggest thing in middle east back in the 80s.
hey they were able to do it, we can as well.
