Time Out says
Despite being right next to the amusement park of Tokyo Dome City, Koishikawa Korakuen feels so peaceful that you almost forget that you're in the centre of a metropolis. The garden was first laid out in 1629. It’s now only a quarter of its original size, but it’s still beautiful, with a range of walks, bridges, hills and vistas (often the miniatures of more famous originals) that encourage quiet contemplation.
