The Osaka e-Pass is a truly useful pass. If you use it on a weekend, you can purchase the Osaka Metro Pass for 620 yen at subway station vending machines. With a relaxed itinerary, you can visit Shitennoji Central Temple (the garden is closed), Osaka Gozabune, Glico Museum, and Shin-Osaka Hananoyu... It's a great pass that allows you to enjoy sightseeing and relaxation simultaneously while saving money. Highly recommended!
