Enjoy a more relaxed pace of sightseeing — and maybe even get a little spiritual — at Hoon-in Temple. If it's possible to venture inside, why not pause for a moment of quiet self-reflection?
You'll find this place of worship in Chuo. Once you've done all you can at Hoon-in Temple, take a look at nearby Osaka Castle, Osaka Aquarium Kaiyukan, and Osaka Science Museum.
