9,772 Unicode characters. (This answer applies specifically to the
Adobe-Japan1-4 glyph complement, and fonts that contain that glyph
complement. Specification is at
  <http://partners.adobe.com:80/asn/developer/technotes/fonts.html>
The answer comes from counting the entries in the UniJIS-UCS2-H CMap file at
  <http://partners.adobe.com/asn/developer/technotes/fontinfo/japanese.zip>.)

No.

See Adobe Technote #5078, "Adobe-Japan1-4 Character Collection for
CID-Keyed Fonts", Sections 1 (Introduction) and 7 (Additional Glyphs for
the Adobe-Japan1-4 Character Collection), at
  <http://partners.adobe.com/asn/developer/pdfs/tn/5078.Adobe-Japan1-4.pdf>

'In order to satisfy the needs of professional and commercial printing in
Japan, a wide variety of character and glyph sets were studied. These
included common vendor extensions, proprietary glyph sets, common "Gaiji"
sets, and other Japanese character sets. Adobe-Japan1-4 is not intended to
be a "Gaiji Solution," but rather is designed to meet most of the
professional and commercial printing needs in Japan. Put simply, the
Adobe-Japan1-4 character collection is specifically designed to allow very
sophisticated users to compose complex documents, with a minimum use of
"Gaiji" fonts.'
