Sengoku-iwa, Gigantic Rock, on Mt. Nagara

The origin of the name, Sengoku-iwa, varies: a gigantic rock looks like a piled-up 1,000-goku [sengoku in Japanese: approximately 2,500 straw rice-bags, which is about 180,000 liters]; the rock face was as vast as 2,500 straw rice-bags laid down; or a vessel carrying about 180,000-liter-worth of goods used to be moored when Lake Biwa was much larger than now. Whichever the origin was, the rock is believed to have been attracting worship from people in the past as iwasaka, a rock containing a god.
