History of Japan

The first symbols of civilization on the Japanese Archipelago appear approximately 10,000 BC with the Jomon culture, characterized by a Mesolithic to Neolithic semi-sedentary hunter-gatherer lifestyle of pit dwelling and a basic form of agriculture. Weave was still unknown and clothes be often made of bark. The Jomon people made bedecked clay vessels, however, often with plaited patterns. Some of the oldest surviving examples of ceramic in the world may be found in Japan.

The Yayoi period, early around the third century BC, introduced new practices, such as wet-rice farming, iron and bronze-making and a new style of pottery, bring by migrants from China and Korea. With the development of Yayoi culture, a mainly agricultural society emerged in Japan.

Denim

Denim, in American usage since the late eighteenth century, shows a rough cotton twill textile, in which the weft passes under two (twi- "double") or more warp fibers, producing the memorable diagonal ribbing specialized on the reverse of the fabric, which distinguishes denim from cotton duck. Denim was conventionally colored blue with indigo dye to make blue "jeans," though "jean" then denoted a different, lighter cotton textile; the up to date use of jean comes from the French word for Genoa, Italy (Gênes), from which the initial denim trousers were made.

Diesel

Diesel engine cars have long been admired in Europe with the first models being introduced in the 1930s by Mercedes Benz and Citroen. The major benefit of Diesels is a 50% fuel burn competence compared with 27% in the best gasoline engines. A down side of the diesel is the presence in the wear out gases of fine soot particulates and manufacturers are now preliminary to fit filters to remove these. Many diesel motorized cars can also run with little or no modifications on 100% biodiesel.
