Checking map, contacting with people, searching for something, etc. etc.
Internetting is essential, especially you travel abroad.
Japanese 3 major mobile phone company companies NTT DoCoMo, au (KDDI), and SoftBank provide the maps, showing how far each company’s frequency reach.
Case 1: Mt.Fuji
First of all, for a limited time of period roughly between July through September, you can get connected around the summit.
The three companies specially offer it to make countless numbers of visitors every year easily be connected.
Beyond that, SoftBank is the best. They offers almost the entire area of the mountain.
The remains only cover a half of the area.
Although they are available only in Japanese,
I just put links to network compatibility maps offered by them in one place.
Good trip starts from good preparation.
Hope your travel in Japan will be memorable.
