An incredible journey up and over the mountain. The best way is to buy a Tozan "free" pass. It is not free, but allows you to go on and off the railway, a cable car (or funicular), a ropeway as they call it (really a gondola), a large boat made to look like a pirate ship and their buses. In my opinion, a bargain for what you get. The railway switchbacks up the mountain for spectacular views and the gondola crests over a peak in the mountain to reveal a sulfur mine. A treat at the peak is to purchase eggs boiled in the sulfur water, which turns the shells black. Supposed to bring good luck. They were delicious. A fantastic journey.
