AKB48‘s Yokoyama Yui announced on SHOWROOM recently that the next 48 Group would be located in Mumbai, India. Yes, they are going with Mumbai48, or MUM48 (lol), and they’re set to debut in 2018.

MUM48 are the fifth overseas 48 Group after JKT48 (Jakarta, Indonesia), BNK48 (Bangkok, Thailand), TPE48 (Taipei, Taiwan), and MNL48 (Manila, Philippines).
This news was later confirmed in a report, which I was waiting for because I kinda thought this was some kind of prank. From what I’ve gathered, everybody is as perplexed by this decision as you are right now.
