The Miho Museum, designed by the renowned architect I.M. Pei, is a place I've wanted to visit for many years, but its remote location and inconvenient transportation made this day trip a dream come true. Staying at a hotel within the Osaka Loop Line allowed the travel agency to arrange hotel pick-up and drop-off, which was incredibly convenient and a major reason for my recommendation. Mr. Nakazato served as both our guide and driver; he was friendly, spoke excellent Mandarin, and even offered to help us take photos at the attractions, making this day trip a truly memorable experience.
