You know most of Japanese are short. We are to fit in this small island. There was a face mask in my house exactly like this, and it scared me so bad. I could not go to the bathroom at night because I thought this mask was alive in the dark. Japan is a volcanic country.
Earth quake is an everyday event.
Volcanos birng us great gifts, hot springs. Natural hot springs are everywhere, and even monkeys bathe. Especially during winter, they like to stay in the tub. However, they have to go to find some food eventually, and they have to get out of the tub. It is horribly chilly for their wet body.
