I inquired on both sites. Both responded back that they can only source the part, not provide a part number. Seems like an odd response or just poor service.
Use the part number of my JDM rear headrest:I was able to get some information on the Caturra Brown headrests from parts-sale.jp yesterday. This is what they replied with after giving them my VIN and sending them a picture with the headrests circled:
K33188240 13
PRICE: 56.67 USD x 2 = 113.34 USD
STOCK: Backorder, January 23
I believe the top entry is a part number of some type. Probably the stock number on their site. Becuase it's not a standard Mazda part number as far as I can tell.
Use the part number of my JDM rear headrest:
K072-88-240 02 - 2016 CX-5 Black GT Leather with Black Stitching
The part number K331-88-240 13 is a legit Mazda part number. The price (MSRP) is about right too. The only question is if this JDM rear headrest is the one matching the Caturra Brown leather for your CX-5 Signature.
So which of these 2 Japanese sellers is cheaper with shipping?Japan Parts also confirmed the same part number. And they've listed it on their site with the same expected ship date of January 2020. I will likely order them soon.

I hope this works out and the color matches the Caturra Brown of the US Signature trim. I'd be in for a pair. No rush for me so the slow-boat shipping would be acceptable. Since these aren't exactly fragile, I wouldn't be too concerned about handling care.
My back seats only get used about once a month (if that), so I just remove those big headrests and put them under on the floor under the front seats.
