Unitech's Intermedia branch used to manufacture DVD media in Japan (with UTJR and IMC JPN codes), but I didn't know they made CDs as well. I am not sure what happened to them, but you can still find some old stock sold under the Unifino brand. They were very good media, better than Maxell... I still have about 30 pieces left.
Here's a sample scan of a 4x DVD-R disc burned at 8x by BenQ DW1640.
I hope their CDs are just as good.
