Shinjuku Gyoen National Garden, Tokyo

A park is an area of naturally occurring, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. There are also amusement parks which have live shows, fairground rides, refreshments, and games of chance or skill.

Wonderful, Japanese-style public park. You can enjoy different types of trees and flowers blooming year-round. If you intend to come here often, I recommend a one-year pass. Costs 2.000 JPY and is created on the spot. Currently (April 2021) you need to preregister through their website to enter the park (not necessary with an annual pass). Also features a nice Starbucks inside (currently drinks only served to go, but you can sit outside on a bench or on the lawn).
