If you want to rent a wifi router for your travel in Japan, here are some basic things (101) you should think about before you make a decision.
Once you sign (or check the box) on the contract, you will be charged for the entire period of time for the router you are going to rent, regardless of what kind of signal you receive. So let's make sure you will get good connectivity in the area where you are going to stay and travel.
Although Japan is well covered, if you are planning to go to a remote area and not sure which wifi router works best, be sure to ask, either by calling or email, ahead of time which one is best for a specific area, such as on top of Mt. Fuji, etc. They are happy to discuss.
