The Eiraku Building has iiyo!! (pronounced "ee-yo") on the B1F to 2F floors, and is directly connected to the B1 exit on the Tozai Line Otemachi Station side.
There is a place called Eiraku Koji near the ground exit of the Eiraku Building in the direction of Hibiya, where you can find benches to sit and relax.

Stone benches are arranged side by side, and about 25 people can use them for a break.
Since it is a space surrounded by buildings, not much sunlight comes in, but it's usually empty on weekends.
With plenty of seats, you can also use this spot if you want to eat your lunch in Otemachi.
Also, there is a resting area near the "iiyo B1F Seven-Eleven front resting area" inside the iiyo building, so please consider that as well.
So, why not stop by iiyo or use this as a relaxing spot near Otemachi Station?
