Starting today, May 28th, and running until June 10th, there will be a newly named labyrinth called Wailers Way which is a special area with the goal to kill as many Oni as possible, and to reach a minimum specified score. Winners will receive a bundle of in-game prizes, so join in! All of the eligibility details for Wailers Way can be found on this forum post.
Not to be outdone by the in-game competition, beginning on May 28th and running until June 3rd, we are holding a sweepstakes for a chance to win one of these awesome signed Oreshika art books. The books are signed by the creator of Oreshika, Shoji Masuda and the character designer, Makoto Sajima. For all the details on this sweepstakes please go to this forum post.
We’re excited to leave you with one more exciting announcement before we sign off… We’ve been listening to our fans and we are pleased to launch an Oreshika theme for PlayStation Vita and PlayStation TV, which will be available on the PlayStation Store on June 2nd!

There's an interview with Oreshika creator Masuda at the PS Blog link.
EU already has a SCEE exclusive theme, but it sounds like this will be the Japanese one:
The JP theme launches in EU on the 11th of June. The in-game contest is available there too, though it looks like the artbook is limited to SCEA territories.
Very pleasantly surprised to see the game get any kind of post-launch support for them.
For those who haven't bought the game, it's currently available for just $15 in SCEA's PlayStation Plus sale. If you want to try out the game, there's a demo available as well.
