I don't know if anybody's listening, but I'm going to make two suggestions for JAST:
1) If you can't speed up the localization process, don't make the acquisition of an upcoming title public until you're finished with it.
2) Have a staff blog and keep it constantly updated.
The reasoning behind my suggestions is simple: There are definitely issues going on with marketing to expand the audience,
but your company has just as many issues trying to internally market itself to its own audience.
Consider this: How long does it usually take for you guys to release a title after you announce that you've gotten the rights to localize it? Three to four years? Possibly five?
With my first suggestion, it addresses a very significant issue: You can't expect your own fans to stay hyped for an upcoming game if they have to wait years before the actual release date. I pretty much forgot that you guys acquired Starless back in 2011-2012 until you announced it a few months ago. Would it be difficult to believe that many others may have forgotten about it in the same way?
Negotiate the license to a game and work on it for however long it takes, then announce/market the title once you've completed the localization (or at least 95~99% finished). Do not annouce anything about an upcoming title until you're ready to come up with a definitive release date.
Obviously, you need to find a way to release a game faster. However, by witholding any announcements for future titles until you're finished localizing it, you can devote your time/money to market it after the localization process. Fans will also retain their interest better because they won't have to wait as long once they realize that you've acquired it.
With the second suggestion of starting a blog and keeping it constantly updated, I'm taking a page out of Mangagamer's playbook. As niche of a company as they may be, the most intelligent marketing decision they made was to create a staff blog, and keep it fresh with updates.
Sure, both you and MG have Twitter and Facebook accounts, but you can't put as much content in either of them as you could with a regular blog post.
Even if you don't have anything to announce as far as updates or release dates, you need to keep it fresh with relevant content. You can add things like staff/translator/artist commentary for specific titles or related news events (like upcoming cons).
The whole point is to keep fans interested while they're waiting for new titles to come out--It's only been ten days since May 1st, and MG has over six blog posts (normally they have over ten a month). By constantly updating a blog with content related to either your games or the VN market, you show fans that you're still at work. It prevents your own fans from thinking you guys are dead.
You guys have a devblog on Tumblr, and that's a good start. However, you need to put more content in your posts. MG often writes multiple paragraphs worth of detailed content each of their posts, whereas a lot of the posts you guys have are 1-2 liners accompanied by a few pictures. At its current state, your Tumblr account might as well be just a glorified Twitter account.
I'm not even sure if Tumblr is the best blogging platform out there. I never liked the interface myself, and it's rather difficult to navigate posts.
If you're using your devblog to market yourselves to potential fans, it would also help to make the link to it more prominent and easier to find in your front page. MG has a button near the top left of their front page that says "STAFF BLOG". On the other hand, your users have to scroll all the way to the bottom of your front page find the link to your devblog (written in small, hard to read letters, I may add). Don't assume all of us are capable of finding anything.
Actually, now that I think about it, it would also help if you did the same for links to this forum. It's kinda hard to find your messageboard and talk to you guys if the link to it isn't easily accessible from your front page.
