There's Sanei Park near the Shinjuku Historical Museum.

It seems that it was originally the site of Yotsuya Elementary School.

It's a spacious park, and restrooms are also available.

It's a popular spot for families on weekends.

There are many benches in the park, so why not stop by when you're strolling around Yotsuya/Arakicho or visiting the Shinjuku Historical Museum?
So, how about using it as a resting place near Akebonobashi Station?
