Unless there's either a database you can fetch it from, or CD-TEXT on the disc (which is rare), you'll have to put the titles in manually.
You can provide a picture (they don't necessarily have to be
scanned in) and I can compile a tracklist for you if it's only a few cases you need help with. If it's more than a handful, might I suggest having a look at
this thread? (Specifically the "looking up Japanese characters" section)
