Here is a very small Japanese park with a capsule hotel, Ferris wheel, child coaster with custom L grider track, patio sitting area, vending machines, trashcans and many blue chairs to sit on.

I have put in so far: two kiddie train rides, 3 trampolines, a Ferris wheel, a roller coaster, 10 vending machines, three trashcans, a big patio sitting area, a capsule hotel, 25 chairs to sit on and rest, 3 trampolines, a men and women's bathroom, a cycle railway and still have more to put in.
