As the tallest structure in Tanko Park, Constellation Tower is a public artwork that offers visitors impressive views of the surrounding landscape and mountains in the distance. Comprised of circular platforms encircling a central spiral staircase at varying elevations, each platform is strategically oriented toward distinct points of interest within and beyond the park. These platforms also enable visitors to engage with each other by providing diagonal upward and downward sightlines.

Taking on the appearance of a three-dimensional constellation of elements, the Tower's triangulated structure conveys an impression of ethereal, suspended disks in space. These disks feature perforations that permit the passage of sunlight or raindrops, producing captivating effects that are contingent on weather conditions.

Functioning as an iconic landmark within TANKO Park, the Tower of Rain plays an important role in guiding visitors and stands as a symbol of the park's popularity. TANKO Park, a beloved public space, is renowned for hosting a plethora of cultural facilities and events, enriching the community's cultural experiences.
