Questions
›What car has a VIN starting with JH4?
A Acura built in Japan — typically Japan-built NSX, TL and RSX. The three characters identify the manufacturer and plant region, not the specific model; characters 4–8 describe the model itself.
›Is JH4 the same as the country of origin?
The first character alone gives the region — J indicates Japan. All three together identify the specific manufacturer and division within it.
›Can I tell the model year from JH4?
No. The WMI says who built the vehicle, not when. Character 10 carries the model year, and character 7 helps resolve which of its two possible years applies.
