To get to Shinagawa Front Building, exit the Central Ticket Gate of the JR lines and head right towards the Konan Exit.
Go straight, keeping Area Shinagawa on your left, and you'll see Shinagawa Front Building on your right.
And, there's a seating area near the entrance of Shinagawa Front Building.

There are benches that can accommodate about 6 people.
Since they are wooden benches, you might be able to take a break while feeling the warmth of the wood on a sunny day.
However, since they are located along a major road, you might notice some traffic noise.
Also, at "Table Seating on the 2nd Floor of Shinagawa Front Building" in the same building, there's a rest area suitable for Nomad/Remote work or desk work, so please consider it as well.
Why not use it as a place to take a break and sit down around Shinagawa Station while you're running errands or shopping in Shinagawa?
