Table 7 Examples of comments presented in networks 1 and 2

— A mountain itself is dangerous, not to mention an active volcano! Genuine mountain lovers prepare substantially in advance of a climb, and will never pass the buck to others [for ending up in a dangerous situation].

— If you want to climb a volcano in a highly volcanic country, please climb at your own risk.

— No wonder mountaineering is dangerous. Not all mountains can be climbed with ease, like tourist spots. It is common sense that people climb at their own risk. Furthermore, we need to recognize that it is dangerous. Mt. Ontake is a holy mountain. Mountaineering, as a leisure activity, should be prohibited on this holy mountain in the first place.

— People who are obsessed with climbing do not take the risks involved seriously. You are going to an active volcano.

— Human beings are powerless before nature. During a fun time, mountaineering on a clear autumn day, mountain climbers suddenly lost their lives. It’s so sad; I can’t bear it when I think about [how the grieving families must feel].

— If a volcanic eruption occurs again, the cost of rescuing victims comes out of taxes. I hope that the local government retains the climbing regulations [in this area].

— Please take part in mountaineering at your own risk. If climbers call for aid, I hope they themselves will pay to be rescued.

— There is always a risk both on mountains and at sea. No wonder that the disaster administrative agency prohibited going to Mt. Ontake because an unexpected eruption occurred. I wonder if it is rational to allocate public funds to build multiple shelters for recreational mountaineering?

— In an ideal world, the police and self-defense forces are inactive, but things don’t go well like in a [TV] drama. I often read claims that victims should not trouble them, but from another point of view, I feel this claim is incorrect, since one of their jobs is to save lives. We should be grateful for their activities and hard work. It is impolite to think that “we are causing [the police and self-defense forces] a lot of trouble.”
