K. Tamabi has posted that Chad Stahelsi and cinematographer Dan Laustsen visited the Hachioji Campus Library on September 11, 2019 as a possible location for John Wick 4. They checked the lay out of the arcade gallery on the first floor and the open area on the second floor.
Hachioji Library was designed to complement its physical location. The building’s arches, made of steel and concrete, along with the surrounding glass walls, flow with the land that the library sits on. from Wikipedia
