How to add version release name like as (Japanese Edition, Limited Edition, etc.)
You can add that information in the disambiguation comment field when you edit a release.
Too should use extra title information and not title style caps.
this that Japanese edition
This That Japanese Edition
But it is rather redundant with the release event country. So we should not set these particular information IMO
Unless the region is important, we should focus on the other aspects of what makes a release remarkable enough to warrant a disambiguation comment. Such as:
Gold limited edition
or if there are several “red editions”
Japanese red edition
or even mistakes on an edition:
US edition with truncated track 11
