There are a lot of good reasons to have wireless Internet on mountains. Climbers could use mobile devices to check weather alerts. They could notify authorities if something goes wrong. They could also access GPS to find their way.

And they can post gorgeous Instagram photos like this:

And this:

Japan announced this week it will activate WiFi hotspots up and down Mount Fuji, the largest mountain in the country and arguably its most breathtaking natural beauty, in a bid to increase tourism.

Starting Friday, climbers will have 72 hours of free Internet access when they begin their climb up the mountain.

Between 40,000 and 50,000 foreign tourists hiked the main trail last year, Japanese tourism officials told the Asahi Shimbun, Japan's leading daily newspaper.

But Mount Fuji is not the most remote place in the world with wireless Internet access. Here are some others:

Mount Everest

Yes, Mount Everest has WiFi. The hotspot was installed in 2010 at 17,000 feet, the last base camp before climbers make a push for the summit.

Donkeys in Israel

Donkeys wandering around a biblical-styled resort in Kfar Kedem were equipped with wireless hotspots in 2012. Tourists at the site are encouraged to dress in garb traditional of biblical times, and some people like posting photos of their experience online right away, owner Menachem Goldberg told Israel Hayom in 2012.

The North Pole

For some reason, we humans are obsessed with putting Internet in really cold or really warm places. The North Pole has had WiFi since 2005, when Intel set up a network there.
