You’re a cute girl just peacefully evaded people so you can go to buy the marbles for your indoor hobbies when suddenly a wild Hinata appear! And asked you to join her mountain climbing..
Yama no Susume is an anime about cute girls mountain climbing. It is a 12 episode short anime you can watch in just under 40 minutes.
Aoi prefers indoor hobbies and is afraid of heights, but her childhood friend Hinata loves to show off her passion for mountain climbing. As young children they once watched the sunrise from the top of a mountain, and now they’ve decided to take up mountain climbing in hopes of seeing that sunrise again. They have cooking battles with mountaineering gear, climb small hills in their neighborhood, and meet new mountaineering friends as they learn the ropes of the hobby. When will they finally see that sunrise again?
I thought this is impossible for them, coz I saw how hard it is to mountain climbing for real. But then after a few episodes, I realized everything has the “easy mode for beginner” after all.
It seems that there is also un-aired 13th episode of the first season I watched on Youtube while I am writing this post. This first season setting up the story, so I am guessing the second season is when they actually try more real mountain climbing(still looking for a source to watch them). It is also fun to learn new things about climbing.
