The HEART is a digital sign that allows visitors to experience the movement of the vibrant Japanese economy. It stands in the atrium of the Kabuto One office building, which opened in August 2021 in the Nihonbashi Kabutochto neighborhood of Tokyo, Japan. The HEART symbolizes the source of the blood flow that circulates through the Japanese economy. The iconic design of this cubical display, with separate rotating LED panels, processes stock-price data in real time, incorporating that data into an abstract visual presentation that embodies the image of a beating heart. Even visitors who are not familiar with stocks and economics can intuitively experience the cycles, pulse, and passion of the Japanese economy.
