A bar run by a gyaru mama and her girls, the perfect place to end a summer night.
About
A small port town that draws crowds seeking the sea. While it bustles with tourists in the summer, the town itself remains peaceful, with time flowing at a gentle pace. By day, it's a beach shack filling the bellies of swimmers, but by night, it transforms into "Yunagi," a bar designed to bring a summer day to a perfect close. Run by a gyaru mama and a team of part-time girls, Yunagi is a place where everyone can spend time exactly how they wish. Yunagi was born from the renovation of an old shipyard that once stood on the shore. As a result, a heated pool—the symbol of the shop—sits in the center and is available for use. Rather than for serious swimming, most guests use the pool for splashing around or soaking their feet while enjoying a drink. At night, blue lights illuminate the water, reflecting swaying patterns onto the ceiling. The girls have bikini changes ready and can jump in to swim at any time. Customers are welcome to enter in their swimwear, making for a lively atmosphere. Private booths are also available.
