琵琶が日本に伝来したのはいつ
The biwa came to Japan in the 7th century and it was evolved from the Chinese instrument pipa, while the pipa itself was derived from similar instruments in Western Asia. This type of biwa is called the gaku-biwa and was used in gagaku ensembles and is the most commonly known type. While the route is unclear, another type of biwa found its way to the Kyushu region, and this thin biwa (called mōsō-biwa or kōjin-biwa) was used in ceremonies and religious rites. Before long, as the Ritsuryō state collapsed, the court music musicians were faced with the reconstruction and sought asylum in Buddhist temples. There they assumed the role of Buddhist monks and encountered the mōsō-biwa. They incorporated the convenient aspects of mōsō-biwa, its small size and portability, into their large and heavy gaku-biwa, and created the heike-biwa, which, as indicated by its namesake, was used primarily for recitations of The Tale of the Heike.
