To get to Nakano Sunplaza, go through the JR Line North Exit ticket gate, cross the pedestrian bridge, and head towards the bus rotary on your left. You'll see it right there!
Near the bus stops in the rotary, in front of Sunplaza, you'll find a place to sit and rest.

There are three sets of three-seater resin benches.
The benches are spaced apart, and there's plenty of legroom, so you won't feel cramped. However, don't expect the most comfortable seating experience...
Also, the benches are in a relatively visible location, and the resting area can be seen from the pedestrian bridge in front of the station. If you're concerned about being seen, you might want to avoid this spot.
During events at Sunplaza, the entrance area gets crowded, so it might be difficult to use the benches then.
Why not give it a try as a place to sit and rest around Nakano Station?
