It should be if it's in Sony's Headquarters! From former Walkman Designer's, Akiraa Tanaka's Twitter Feed https://x.com/akiraa_tanaka "This is the first-generation Walkman Room, built at the former Shibaura Tech (now the head office), and the second-generation Walkman Room, built at Shinagawa Tech after the relocation. Currently, a third-generation Walkman Room has been established at Osaki Tech, where the Walkman design team is based, and it is used for interviews and other purposes." Even the chairs look like a little like the Walkman Logo.
