Can I Still Get Connected with Japan Prepaid SIM/Pocket WiFi? / Case 5: Koyasan Okunoin w/ English Website Link

Checking map, contacting with people, searching for something, etc. etc.
Internetting is essential, especially you travel abroad.

But, even at famous tourist spots, Japan sometimes has no connectivity with the internet.
How do you know that beforehand?

Japanese 3 major mobile phone companies NTT DoCoMo, au (KDDI), and SoftBank provide the maps, showing how far each company’s frequency reach.

But unfortunately, these are available only in Japanese.
So, in this page, I checked it on behalf of you.


Case 5: Koyasan Okunoin


Koyasan Okunoin is one of the most tourist spots, which got huge popularity in 2017 at TripAdvisor. You can read over 800 feedback in English to Koyasan Okunoin at TripAdvisor.

Koyasan has provided a great website for the area in multiple languages.
It definitely helpful for travelers: A Guide to KOYASAN


As for connectivity in the area, you need to pay some attention as Koyasan Okunoin is located at the middle of mountains.
According to my research, today, SoftBank is the best. They offers a good network even around the area to some extent. NTT DoCoMo provide good next to that.

On the contrary, among the three, au (KDDI) is the weakest on the area at this point. You might be connected just on the spot, however, you might lost the connectivity if you go even further from it.

Although they are available only in Japanese,
I just put links to network compatibility maps offered by them in one place.
If you want to check it through the links below by yourself, put Japanese “奥の院” into their search windows.
SoftBank *Hard to search by yourself alone
au (KDDI)

If they can not help you at all, or if you have a specific area to be checked,
