Tsunku produced group from his Akihabara Backstage Pass idol cafe, Bakusute Sotokanda Icchoume, will be debuting next August with an indie single.
The cafe was opened in December 23rd, with 80+ girls chosen from about 1000 applicants. Here's an explanation about the cafe from Tokyohive:
Visitors to the cafe will be issued an employee ID card to the imaginary management company, “Ruaido Geinousha”, a play on words of the word ‘idol’ (aidoru). As ‘producers’, any foods, drinks, or goods purchased in the cafe will earn the customer “Producer Value Points”, which they can then use to support their ‘oshimen‘ out of the cafe’s workers. Aspiring idols working at the cafe will be given booking preference for outside activities if they accrue a high number of points. As customers climb through the ten “Producer Ranks”, they will be able to earn more points and therefore contribute more to these potential idols.

I've heard Tsunku's cafe is really awesome. And they're not affiliated with Hello!Project in any way, in case anyone was wondering.
