Complete waste of money
Complete waste of money! I can't believe we took the time to reserve and pick up one of these hotpots while in Japan. Once your data becomes throttled it is basically unusable. It ended up being pointless for us to lug the hotspot around and make sure it was charged. Although many places in Japan have wifi, getting to those places can be quite difficult if you don't have the data to navigate or look things up on your way. Save your money! Rent from somewhere else or go with a different means of a data plan.
