To get to Ebisu Station East Exit Park, exit the JR Ebisu Station ticket gates and head towards the taxi rotary of the East Exit. You'll find it there!
Inside the park, there are public restrooms and a smoking area, and there are resting places with benches around.
There are four 3-seater wooden benches installed.
The benches are dotted around the rotary side, near the skylight, and inside the park.
Although it's called a park, there isn't much greenery, and it's a bit of a lonely park with not very clean public restrooms and a smoking area where people gather.
It's very close to the station, and there are also vending machines, so it seems like it could be used as a meeting spot.
Why not try using it as a place to rest in the Ebisu Station area?
