This picture is from Shinjuku Gyoen National Park.
Parks like these are to be plentiful in the Land of the Rising Sun. Of course you have to pay to get in (this one was only $2 USD). But as you can see, it’s worth the price of admission. With the general over-population of the Japan as a country, combined with tourism being the main money-maker at most city centers (Shinjuku, included), I’m sure the head honchos make a killing.
Conversely, having to pay for admittance also keeps the homeless out.
I’m not making some big statement about helping the poor. I’m just pointing out the contrast of entering a public park in Japan while it’s own less fortunate citizens have taken residence outside of the park gates.
