First of all, Japan is not a small island...it's a gigantic linkage of many island that extends from south korea, all the way to Northern China/Russia. It is as long as ATL to Maine. To know true JDM mileage, you will have to get the clip...and what the odometer says..is probably true.

When we used to live in S. Korea, my dad drove only 4-5000 miles a year..so that explains a lot...but engines do have much more wear b/c they are all traffic mileages..
