Love the idea, but strange UX.
Edit: tried it again and I think the problem is that there's no feedback during scrolling during transition screens. When I scroll, I expect it to scroll with me, not go on its own path. So by the time it's possible to scroll again, I already tried everything and gave up. Made more confusing by the instructional text disappearing between transitions. Give a little bit more feedback during those transitions and I think the problem goes away.
Oh hey, I met that guy. He stopped his run down to point me back to the trail after I wondered off having lost the markers somewhere on my evening ascent between the 7th and 8th station on the Subashiri trail. Made a joking comment about his not staying for the sun rise -- he already caught it on his first run up earlier that day...
Many on a short holiday with minimal hiking gear or local knowledge.
Along the way you can meet many elderly people who have climbed it multiple times.
Kids climb it.
If one is in decent shape, brings some water and rice balls, it's a nice slow adventure to the top. Unless you get super unlucky with weather.
