You can try. Some dealers can pull JDM parts from their US system if you had the JDM Honda part number for the part. Then it can be ordered. If you can find a part number for the badge, call your dealer and tell them you want that part by the number. They may or may not be able to order it. If that doesn't work, you can probably get one on the internet, eBay, etc.
