Because soft and easy to process the Izu Stone (tuff) which colcanic ashes deposited when Izu Peninsula was a submarine volcano, and was made, it has been used for a long time. It was lowered by a rope from here, and on the occasion of Edo castle construction, Izu stones cut and brought down by 84.8*15.2*18.2cm and 91*15.2*18.2cm two kinds of standerds was carried to Edo by ships.
The eight islands of Japan sprang into existence through Divine Intervention.The first two gods who came into existence were Izanagi no Mikoto and Izanami no Mikoto, the Exalted Male and Exalted Female. It was their job to make the land for people to live on.They went to the bridge between heaven and earth and, using a jewel-encrusted halberd, Izanagi and Izanami churned up the sea into a frothy foam. As salty drips of water fell from the tip of the halberd the first island was formed. Its name was Onogoro.So far, so good. But when Izanagi and Izanami first met on their island, Izanami spoke to Isanagi without being spoken to first. Since she was the female, and this was improper, their first union created badly-formed offspring who were sent off into the sea in boats.The next time they met, Izanagi was sure to speak first, ensuring the proper rules were followed, and this time they produced eight children, which became the islands of Japan.I'm sure you did not fail to miss the significance of this myth for the establishment of Japanese formal society.At present, Japan is the financial capital of Asia. It has the second largest economy in the world and the largest metropolitan area (Tokyo.)Technically there are three thousand islands making up the Japanese archipelago. Izanagi and Izanami must have been busy little devils with their jewelled halberd...Japan's culture is highly technical and organized. Everything sparkles and swooshes on silent, miniaturized mechanisms.They're a world leader in robotics, and the Japanese have the longest life-expectancy on earth.Text by Steve Smith.
