Spear
Japan

The hoko spear was used in ancient Japan sometime between the Yayoi period and the Heian period, but it became unpopular as early samurai often acted as horseback archers. Medieval Japan employed spears again for infantrymen to use, but it was not until the 11th century in that samurai began to prefer spears over bows. Several polearms were used in the Japanese theatres; the naginata was a glaive-like weapon with a long, curved blade popularly among the samurai and the Buddhist warrior-monks, often used against cavalry; the yari was a longer polearm, with a straight-bladed spearhead, which became the weapon of choice of both the samurai and the ashigaru (footmen) during the Warring States Era; the horseback samurai used shorter yari for his single-armed combat; on the other hand, ashigaru infantries used long yari (similar with European pike) for their massed combat formation.
