This is Sega's PlayStation Vita Golf game "@Field," as shown in a listing at Amazon.co.jp.
This is a bit different from your typical golf game... and not just because of the girls. The game combines mini golf with pinball elements.
The girls shown in the pics are actually "dolls." You can customize them to your liking, presumably via the closet and customize options shown in the main menu.
Modes of play include a mission mode with over 100 missions. Clear each mission, and you'll unlock items, costumes and new fields of play. There's also an edit mode, where you can create your own fields and share with other players, and an ad-hoc mode for local wireless play (it's unclear if the game also has online play).
@Field is due for release this Winter, priced ¥3,990.
