I often climb mountains in Hiroshima. And I sometimes climb the famous mountains in Japan.

Oxygen
I bought oxygen tablets. I don't know whether it is effective or not. In last summer, I had a headache at near top of Mt. Yari, because of lack of oxygen. So, I decide to try it.
If it is effective, it will be a useful item.
