I'm not very familiar with CMSs, but what kind of use case would actually benefit from the tool? Your example actually requires human decision-making, since Big Gangan is a proper noun with a canonical English name. I expect most Japanese devs to be as familiar with romanization as English devs are with spelling and grammar, so a tool shouldn't be needed unless you're dealing with a large amount of text and can allow for errors.
