Toyota Vista Owner's manual

You won't find one as it's a Japanese-only model. The closest you'll get is to obtain a manual for the Toyota Camry, but expect much of the detail regarding engines, transmission and accessories to be significantly different as the Vista is essentially a Camry with different powertrain, trim and extras.

The advice regarding the Camry only applies to Vista models built up to 1998. From 1998 onwards it is a totally separate model and your only option is to get your Japanese manual translated.
