Akihabara UDX 2F JR-side Deck is an open-air deck on the second floor of the Akihabara UDX building at 4-14-14 Sotokanda, overlooking the JR train tracks and city below. It forms part of the UDX complex's second floor, which also houses the Akiba Ichi restaurant district of around 40 eateries and the UDX Conference event spaces.

The deck is a popular spot for fresh air and train-watching, often featured in Akihabara social media posts for its open rooftop-style atmosphere.
