Shinjuku Gyoemmae in Tokyo had lots of grass and people sitting on it including from what I can tell Japanese people. Hiroshima has green areas along the rivers complete with park benches. Kyoto has Arashiyama but that is on the outskirts of the city. That has beautiful walking paths and benches. What I didn't see is people sunbathing. That doesn't seem to be a thing like it is in Europe.
