Terms for Japanese/Western name order


Does anybody know of a standard term to describe Japanese and Western name
orders (for example, when filling a form):

> John Somelastname ← "Western name order"
>
> Somelastname John ← "Japanese name order"

Short of an exact term for each form, what construct would you use if you had
to tell somebody to use one instead of the other? or tell someone which one is
which, in a document where both would be present.

To clarify: I am not asking how to say "write first name, followed by last
name" or some such step-by-step instruction, but a self-contained descriptive
term for the forms themselves.




What about:

> 姓－名の順
>
> 名－姓の順
