u mean u r going to import them from jap or it's imported already?
as far as i know it's pretty impossible to import a EK4/9 unless u owned it overseas for more than 2yrs
plus u need to give proof of "daily driven ownership" (like petrol receipt, maintenance and shits)
in that case u might be able to import them as a personal import
after that u still need to do RWC check and shit loads of procedure b4 u can drive it on the road
imo not worth the trouble even if u hv been owning it overseas
