SCPM: Well, like GOG said in the community Q&A video about bringing Japanese publishers here, it'd help for the community to write to them.
The problem is, Japanese publishers won't listen. Correspondence like that is promptly ignored. They won't even listen to the US/UK branches of their own company for goodness sake! So mere customers, whether Japan based or not, are going to get nowhere when it comes to contact the Japanese branch.
This desire for a lack of communication with customers is part of the reason why PSN remained offline in Japan for over a month following that security breach. The Japanese government wouldn't let them back on online until they had meet certain criteria, one of which was customer interraction; which Sony now do to the barest minimum with a blog.
For that matter, Square Enix used to listen to PC customers. It's why we have some of their games on Steam. But they ceased doing that a year or so back. Now they won't respond to any questions regarding the PC.
