If it's a good or bad move I don't know.
If this is Wasamin's dream, and desire - then of course I support it, and I am happy for her. If not, then of course I will be a little more hesitant.
But no I haven't heard of Nagara Production either. World of enka isn't really my thing although I like a ton of enka. I just don't know about agencies and such in this context.
Just having googled, it seems that Hikawa Kiyoshi is on Nagara Production, and he's pretty much known as the Prince of Enka... So that's real nice.
Here's more artists on Nagara Pro:

They have Mizumori Kaori (水森かおり), and she's as awesome as it gets.
Anyways, there's two options as I see it:
- Wasamin graduates from AKB48 to focus on her enka career.
- Wasamin stays in AKB48, and becomes their enka girl so to speak.
At this point in time I don't know what will happen.
