Splatoon 2
Deca Tower is a skyscraper covered in large billboards, some of which are electronic. It highly resembles the real-life One Times Square building located in New York City. After the Great Zapfish is rescued, it can be seen resting atop the Tower.

The Tower's base features a lobby entrance similar to Inkopolis Tower's, featuring an elevator-like entrance surrounded by electronic screens showcasing the currently available stages. Above the lobby entrance, a total of 19 billboards are affixed to the Tower, two of which are electronic; one electronic billboard is rectangular and prominently placed at the front of the Tower, while the other electronic billboard is shaped like a massive version of the smartphones Inklings can be seen using, complete with an oversized charger connector plugged in.

Splatoon 3
During the events of, the mysterious Spire of Order replaces Deca Tower in "what has become of" Inkopolis Square in "what would've happened if" Team Order had beaten Team Chaos. This alternate version of Deca Tower appears to be a dilapidated, bleached out version of it.
