There are also some bronze vestiges to which considerable interest attaches, for evidently people using bronze weapons could not have stood against men carrying iron arms, and therefore the people to whom the bronze implements belonged must have obtained a footing in Japan prior to the Yamato, unless they came at the latter's invitation or as their allies. Moreover, these bronze relics--with the exception of arrow-heads--though found in the soil of western and southern Japan, do not occur in the Yamato sepulchres, which feature constitutes another means of differentiation. Daggers, swords, halberds, and possibly spear-heads constitute the hand-weapons. The daggers have a certain resemblance to the Malay kris, and the swords and halberds are generally leaf-shaped. But some features, as overshort tangs and unpierced loops, suggest that they were manufactured, not for service in battle but for ceremonial purposes, being thus mere survivals from an era when their originals were in actual use, and possibly those originals may have been of iron. Some straight-edged specimens have been classed as spear-heads, but they closely resemble certain ancient bronze swords of China. As for bronze arrow-heads, they occur alike in Yamato sepulchres and in the soil, so that no special inference is warranted in their case. The bronze hand-weapons have been found in twelve provinces of southern and western Japan: namely, five provinces of northwest Kyushu; three on the Inland Sea; one facing Korea and China, and the rest on the islands of Iki and Tsushima.
