So, I ordered this Charging Port Cover from a website about two weeks ago

Just got my package from USPS today by EMS.
The total cost for my order was 25,885 Yen (shipped) to Los Angeles.
The installation and user guide are in Japanese only, but pretty much the same as the document posted by mwalsh. Thanks mwalsh!
Took me like 20mins to install, fairly easy (especially for a person like me, who is not handy AT ALL
The orange clip marked "L" should be installed on the driver side (US) of the car, with the "shorter" opening facing UP (with lid opened)
The orange clip marked "R" should be installed on the passenger side (US) of the car, with the "shorter" opening facing UP also.
The Part number from Nissan Japan is K9002-3NC0A according to the invoice in the package.
I asked about this charge port cover using a form from the website.
3 days later, they told me they added the part to their database, and the part number is cali4-LEAF-001 (not Nissan part number, that's their internal part #)
I just tried to use this number to search on their website, and seems this number is still valid.
I don't know how to post pictures on this forum, but if needed, someone can teach me how to (or refer me to a "how to" page) and I will post the pic of the installed cover on my Leaf.

I was a bit eager to get this cover and jumped the gun without doing much research on the reputation of this site, but my purchase experience was very smooth, they sent me multiple e-mail(s) along the order process.
