 The agricultural surpluses produced by the manorial Yayoi economy stimulated Japan's early handicraft industries and the establishment of urban villages and permanent settlements started to appear in the Yayoi agricultural community as cities didn't exist at that time.As the Yayoi economy became more sophisticated, Japanese craftsmen began to venture in metallurgy and began to develop their own tools such as swords, arrowheads, axes, chisels, knives, sickles, and fishhooks.Decorative items such as ceremonial bells and mirrors were used as religious rituals and status symbols.
