Correct, but you'll be hard-pressed to find them on MacOS Japanese
fonts. Our fonts have them, but they're not directly available on
MacOS (some are available through glyph substitution features).

Of these 360 kanji, 279 are in JIS X 0212-1990. One is a duplicate of
JIS X 0208-1990.

This cannot be correct. Part of the design of the first set of 20,902
Chinese characters was to include *all* of JIS X 0208-1990 (now JIS X
0208:1997) and JIS X 0212-1990. Of the remaining 80 kanji, most just
happened to be in the set of 20,902 Chinese characters (for example,
some of them are traditional forms). So, the characters in the range
0xFA0E-0xFA2D are those not in JIS X 0212-1990.
