I thought Sony MIJ DVD-R is TY?

I went to Best Buy tonight in hopes I could find some TY discs. I purchased this Sony 50 pack that is MIJ and when I use the DVDInfo or Nero Info tool to see who manufactured it it is made by Sony. Are there only certain spindles like 100 packs that are made by TY?

Sony 8x DVD+R that’s MIJ is YUDEN000 T02…DVD-R is a Sony MID…

Sony 8x DVD+R that are made in Japan
