If it says "made in Japan" it is 100% TY. If it says "made in Taiwan" it should be Ritek G03 media. I've seen no reports anywhere that Fuji uses CMC or ProDisk (Princo) as a supplier.
I'm going to pick up a spindle tonight and will report back with the media ID.
UPDATE: I picked up the 50 pack spindle of Fuji DVD-R at Best Buy. They are Ritek G03 blanks and should burn with no problems at 2X on most burners. I saw the 10 pack Fuji DVD-R that say "up to 4X" on the packaging and they are made in Japan. Hopefully, it won't be long before TY 4X is what Fuji uses in all their DVD-R retail packs
