OK, since there seems to be some confusion here.
Readily available 'over here' Fuji instant films:
FP100C in medium format pack film and 4x5 pack film.
FP100B in medium format pack film.
FP3000B in medium format pack film and 4x5 pack film.
Apparently available in Japan but not here:
FP100B in 4x5 pack film.
FP400B in various formats.
FP500B in various formats.
Not available anywhere because they don't make it as far as I can tell:
Anything in 4x5 single sheet form (i.e. Polaroid 545-style single sheets.)
Oh, and the Fuji dataguide can be found here.
