Located north of the Shuinandong settlement in Ruifang District, New Taipei City, the Yinyang Sea is famous for its unique color, which is a mix of blue and yellow. It is a remarkable geographical landscape in the coastal region of Taiwan’s northeast corner. Since the nearby Jinguashi Mountain is rich in pyrite, which forms copper and iron after weathering, an acid called ferrous hydroxide is suspended into the water; this acid absorbs sediment, resulting in the yellowish-blue color that makes the Yinyang Sea so unique. The water in the bay, which as a result of natural minerals is yellowish brown in color, is completely different from the blue seawater; this contrast is often praised as a natural color palette.

On the T-shaped crossroad between Dongding Rd. and Provincial Highway No. 2, a long straight road connects the blue sea to the azure sky and white clouds, bearing a strong resemblance to a classic scene from the famous anime Slam Dunk. Because of this, it is also known as “Small Kamakura”.
