On the way up Kakinokizaka from Toritsudaigaku Station, you'll find a facility and park called Meguro Ward Citizens' Campus.
There's a lawn in the park, which is a popular spot for children.
There are benches nearby, and you can spread out a picnic sheet and enjoy a picnic at Toritsudaigaku.
(I forgot how many benches there are, so I'm looking forward to your comments!)
There is also a Pyramid Plaza, making it an advanced citizens' campus.
So, why not use it as a resting place with seating around Toritsudaigaku Station?
