Found this interesting.

King's Quest V in Japanese language on the FM-TOwns. The acting might actually sound less annoying than the English version. But unfortunately I can't understand a word of it!

Wizard and the Princess by StarCraft (various Japanese computers). With updated color graphics. This is one I would love to see get a translation localization and rerelease!

Hmm, interesting. The music in the opening is standard adlib/soundblaster music. In the English talkie version of 5 (at least the way it's set up on GOG) the music is digital audio rather than synthesised directly.
