This trip to Mount Fuji with my parents, who are in their 80s, was a wonderful experience. We were lucky enough to see several famous viewpoints, and the entire journey was very clean and comfortable in the vehicle. We are truly grateful to Mr. Ryuzawa for his service; he was incredibly patient and carefully helped my parents get on and off the bus. It was a wonderful trip, and we will definitely book again if needed. Highly recommended! 👍
Unlike roaming, it doesn't lag when used; the experience is quite good. It's worth buying if it's cheap. The card seems to have a phone number on it, but I haven't tested it by calling yet. It would be even better if I could leave my phone number to make restaurant reservations.
